Pad swept area: a quick comparison between BMW OEM and Brembo GT.

Published on January 21, 2015 by in Uncategorized
Pad swept area: a quick comparison between BMW OEM and Brembo GT.

The introduction of a monobloc fixed caliper on the F8x M cars was a windfall for M3 fans everywhere, improving not only the appearance and style of the car’s brake system from the factory, but also (and most importantly), the temperature control, stopping power, and pedal feel. The change from the old E92 M3’s sliding multi-piece calipers to the current fixed calipers represented a technological leap, and M fans around the world expressed their excitement.

IND plans to take advantage of the improved brake system found in the F8x M cars by further developing those components, including drop-in brake pad and rotor solutions from industry leaders like Race Technologies and Girodisc, along with pad and fluid packages that will help make the M4 a performer in harsh track environments. Our developments here will help the M community enjoy their cars in HPDE and road course lapping days by making simple, relatively low cost modifications.

With that said, the F8x M cars continue to suffer from BMW M’s tendency of opting for very large brake calipers with a high performance appearance, but coupling those with relatively small brake pads with limited effective swept area. It is this attribute that I wanted to elaborate on in this thread. Brake pad swept area is a contributing factor in nearly all aspects of braking performance, and impacts everything from overall generated friction, to temperature dissipation and rotor wear.

I’ve created a number of CAD drawings in SolidWorks of both the OE BMW brake pads, and a Brembo GT front pad for comparison purposes, to illustrate the difference in swept area between the two kits. My analysis of each pad’s respective area gave the following results:

M3/M4 OEM front: 71cm²

M3/M4 OEM rear: 40cm²

Brembo GT front: 95cm²

Brembo GT rear: 62cm²

The top pads in the below photo are from Brembo’s GT big brake kit, while the bottom pads are part of IND’s OEM fitment performance pad development program.

In the presence of giants- IND’s M4 visits Fall Line Motorsports

Having installed the brand new 3D Design aero kit on IND’s M4, we stopped by Fall Line Motorsports to plan the next steps for our M car. We managed to capture some images while discussing suspension packages for IND’s clients. We were honored to be in the presence of so much racing prowess, and feel truly lucky to be partnered with Fall Line. The ability to offer our clients the combination of IND’s street performance expertise along with Fall Line’s setup, alignment, and race engineering experience is a privilege for us at IND.

IND’s M4 is currently using KW’s Variant 3 coilovers, HRE R101 wheels in 18″, and Brembo’s 380mm GT kit to complete the new look and feel offered by our Eisenmann exhaust and 3D Design aero kit.

Enjoy the photos!

Official info on AMS’ new M5 tune, from IND!

Official info on AMS’ new M5 tune, from IND!

After two years of waiting, the F10 M5’s S63tu engine control has been unlocked to tuners with the M5 community buzzing with a palpable excitement. IND understands that unlocking the car’s engine control is only half of the picture- after learning to effectively communicate with the ECU, we must also understand how to properly modify the engine’s behavior and look at all engine components from a complete system perspective. Changing one aspect of the engine’s behavior will impact all of the other parameters as well.

It is precisely this understanding, and this level of complete system control that an open ECU allows, and a piggy back controller can never achieve. It is precisely for this reason that IND dropped our M5 at AMS for research and development nearly two years ago, eschewing the easy to obtain alternatives offered by cheap, low quality piggy back controllers. Today, we are proud to announce that our (and your) wait is over.

AMS Performance has finally released an Alpha tune for the F10 M5, and as expected the first M5 to be tuned by AMS has yielded incredible results. The months of testing and development on IND’s own F10 M5 have given AMS a running start, and combined with AMS’ incredible knowledge of tuning and engine control systems will now ensure that AMS performance software continues to be an industry leader in the F10 M5 market. AMS has an absolutely one-of-a-kind history within the tuning community. AMS has set records in drag racing, road racing, time attack, and nearly every other form of motorsport, starting from their humble beginnings with DSM cars, and finally moving to Evo and GTR platforms. The tuning community knows that an AMS Alpha car is an absolutely fearsome machine.

AMS’ Alpha tune for the M5 will include:

* 100 horsepower gain over the factory power output
* True ECU reflash, balancing the critical parameters of the engine for safe operation
* Top speed limiter removal
* CEL removal

Eisenmann E9x M3 Signature tips 4x90mm (Limited release)

Eisenmann E9x M3 Signature tips 4x90mm (Limited release)

Eisenmann Exhaust Systems GmbH has been manufacturing exhaust systems since 1988. Eisenmann enjoys two decades of experience as an OE supplier for Porsche, Mercedes AMG, Mercedes McLaren, Reiger Tuning GmbH, AC Schnitzer, and many other firms. The lessons learned as an OE supplier allow Eisenmann to bring this same level of expertise to performance exhaust systems and enabled Eisenmann to create an exhaust for the E9x M3 that is specifically tailored to the S65 V8’s tonal characteristics for the perfect sound along with a power increase.

Eisenmann’s exhaust system for the E9x M3 is undoubtedly one of the best selling units manufactured by the Stuttgart-based exhaust company. The E9X system, like all Eisenmann’s, are constructed by hand to order, and built entirely from 304 stainless steel material. In celebration of such success we petitioned Eisenmann to build a limited quantity of E9X systems featuring the new F8X M3/M4 signature tip. This release will consist of 25 units and is on a first-come, first-served basis.

The signature tip featured on the F8X M3/M4 exhaust is an adjustable 90mm aluminum tip. Eisenmann’s new “Signature” tips are specifically designed to emulate the style of the BMW M tips, to allow our clients to remain within the M realm of design and appearance, while simultaneously having something very unique- the added “LeMans style” inner tip is an Eisenmann hallmark, and has been unique to Eisenmann for over a decade. The brushed coating featured on the outside of the tip is a nano-coating realized through Eisenmann’s experience as an OE producer for Porsche.

The first volley of performance parts by Fall Line Motorsports!

The first volley of performance parts by Fall Line Motorsports!


As Fall Line motorsports prepares for some major announcements during their 2015 race season, we at IND are proud to introduce the new F8x M3/M4 Fall Line Motorsports performance parts program. IND is proud to consider Fall Line a key partner in our ventures, having the pleasure of working with Fall Line for over 6 years to offer safety equipment, bespoke suspension components, and engine performance parts for IND’s Portfolio clients, we are proud to release a line of production parts specifically designed for the F8x M chassis.

One of the most exciting aspects of this project is the opportunity to look at the F8x M chassis cars in a wholesale systems approach. Fall Line’s racing experience, and their plans for the F8x M cars in motorsport enable IND and Fall Line staff to look at each area of the car as a complete system, knowing that an adjustment to one part will have an impact on the behavior of others. Although each part can be purchased separately, the parts presented by Fall Line will be designed to work together in harmony, for the best performing M3 and M4 possible.

The items now being built by Fall Line Motorsports will be a part of an ever-expanding parts catalog, which will continue to grow as Fall Line gears up to race the F8x M cars at the professional and club levels. What follows is a summary of our current efforts, with a basic description of each of the components Fall Line has created thus far. Expect a complete thread for each part in the near future, with more coming soon!

At present, we are proud to introduce the following components:

JRZ RS line of dampers

JRZ suspension was formed in 1994, and created around a need to innovate beyond standard damper technology. JRZ’s proprietary damper design focuses specifically on optimizing control of the vehicle’s unsprung mass. JRZ has found that their dampers result in reduced tire wear, increased mechanical grip, and overall better performance.

The Fall Line JRZ product line is custom tailored for Fall Line Motorsports specifically, and enables Fall Line to apply their analysis of the M4 directly to the suspension they create. The preparation for Fall Line’s 2015 racing program has enabled Fall Line and JRZ engineers to work together to create the best possible combination of damper valving, spring rate, and overall system design specifically tailored for the F8x M chassis cars.

Fall Line front mono ball kit

Fall Line’s mono ball spherical bearing conversion kit transforms the front steering and suspension feel of the M3/4. The factory rubber bushing is very large, and is prone to substantial deflection under load, as the M4 is put through its paces. Deflection of the bushing can create unwanted geometry change, steering wobble under braking, and even hysteresis of the thrust arm.

The Fall Line mono ball kit replaces the large rubber bushing found in the original thrust arm with a top quality spherical bearing by Aurora. The bearing’s housing is precision machine from aluminum, to create a rigid part that allows for the M4’s thrust arm to move smoothly through its range of suspension travel. The improvement in steering and suspension feel is immediate and truly enhances the
personality of the M4.

Fall Line race toe link kit

The race toe link kit by Fall Line Motorsports is designed to facilitate rapid adjustments of toe during an alignment, and combined with the tension strut will also enable adjustment of overall track. Not only does this allow for fine tuning of wheel fitment, these arms will allow an alignment shop to make quick work of car setup, even simplifying the camber adjustment process as a result.

A byproduct of multi-link suspension arrangements is a dynamic change in the car’s alignment settings- when making an adjustment to one attribute like camber, track width and toe will follow. This is especially true for the F8x cars, as the original BMW camber eccentric bolt has a major impact on toe as well. Alignments are made faster and simpler when using a set of aftermarket lower arms, enabling the alignment tech to easily reset toe after adjusting camber.

The race toe links utilize a unique clamp-style fastener system as seen in BMW’s own tie rods and Porsche Motorsport components, tightening the adjustment arm in place with no stretch of the hardware or change of alignment. Less expensive jam-nut designs limit precision and nearly guarantee an alignment change when the jam-nut is tightened. As will all Fall Line suspension components, high quality Aurora bearings are used to ensure a very long service life. ARP hardware is used throughout to guarantee the highest level of durability. Laser cut lockout washers correctly eliminate the original BMW adjustment, eliminating any unwanted movement in the system.

Fall Line Rear Upper control arm bearings

Rubber bushings found in the M4’s rear upper arms are the last weak link in an otherwise rigid suspension. The original BMW bushings yield to cornering forces applied to the suspension, resulting in camber and toe change that is not ideal for performance driving. Fall Line’s kit replaces the soft upper control arm bushings with military spec Aurora brand spherical bearings, enabling the rear suspension arms to move smoothly through their travel and giving the rear of a car a more solid, planted feel. The reduced geometry change allows for the car to retain its desired alignment, maintaining better control over the tire’s behavior under heavy load.

Fall Line tow strap

The Fall Line Motorsports tow strap is the highest quality strap available for BMW M cars. Fall Line combines 5 axis CNC machined stainless steel hardware with a CNC sewn strap for an extremely robust piece that will withstand the rigors of repeated use. The high strength webbing is available in an extensive selection of colors, and can be ordered in custom colors for no additional charge. Each strap is designed to thread perfectly into the M3/M4’s bumper reinforcement for an easy install.

BBS FI-R concept wheels, first look from Essen Motorshow!

Published on December 1, 2014 by in Uncategorized
BBS FI-R concept wheels, first look from Essen Motorshow!

IND and BBS: a history.

I eluded to some new product from BBS in October this year, in this thread:

http://f80.bimmerpost.com/forums/sho…5&postcount=17

We are lifelong BBS fans here at IND- the wheel manufacturer’s commitment to motorsport, technology, and innovation is literally second to none. No other wheel manufacturer in the world has such an illustrious history of racing success. No other wheel manufacturer has so consistently innovated, ever since BBS’ work with the 3 piece wheel in the 1970s.

Most recently, the BBS FI wheel design created an explosion of imitators and replicas. IND was first to introduce the FI wheel on a road-going car in 2010:

http://www.m3post.com/forums/showthread.php?t=445622

Every major wheel company in the business had to have an FI style wheel design to stay relevant, and all did what they could to have a shot at the instant classic. Knowing that this fate was inevitable, I have been asking BBS for a follow up to the venerable FI since our visit to BBS’ German-based Motorsport facility, two years ago:

http://www.m3post.com/forums/showthread.php?t=914945

Introducing the BBS FI-R concept

The BBS FI-R is an idea several years in the making. After holding my tongue to the community since our initial trip to Germany, it is with tremendous relief that I present our first images of the FI-R concept wheel. While this is still a concept and sizing, pricing, and fitments are not yet finalized, we can say with confidence that this wheel is similar in overall theme to the production piece, sans the incredible center lock for BMW applications, of course.

“How can we make the FI better?”

I distinctly recall asking the head engineering at BBS Motorsport. His answer did not surprise me, but did implant itself in my memory-

“If we add a spoke, remove a spoke, or move the spokes significantly, the wheel will be heavier, or weaker, or both. We have done countless calculations to confirm this.”

The FI spoke shape is literally state of the art. It is the lightest possible configuration, devised by a company that has been building racing wheels since the 1970s. Arriving at this point was no small feat, and improving on this design was something initially considered impossible. The next step in the FI’s evolution was even more complex, and shown in the images below.

BBS Motorsport has carved relief holes directly into the spokes. After over a year of development, the engineers at BBS have confirmed that this design is no weaker than the original track-proven FI, and yet even lighter than the already featherweight wheel. Special machines were purchased, specifically to shape these wheels. Although this wheel is not yet in production, I am confident that the FI-R will set the bar for years to come.

Please excuse the quality of the images- IND had a limited presence at the Essen show, and will capture better images as soon as possible.

Bonus images
We also captured some bonus images of classic BBS Motorsport wheels, featured at the Essen show:

A history continued: IND installs an Eisenmann exhaust for an M fanatic.

A history continued: IND installs an Eisenmann exhaust for an M fanatic.

We are grateful every day at IND for the longevity offered to us by our clients. Thanks to each and every IND client, we have the privilege of watching the ebb and flow of BMW M cars over the decades. We have watched the M brand evolve and grow, and feel lucky every single morning when we come into the office and have yet another opportunity to work with BMW’s latest and greatest. This longevity has granted us a sense of perspective- an ability to remember M models that are long gone, and use BMW M’s history book to make our choices.

From time to time, we are fortunate enough to work with an M fan that has a similar sense of perspective, and a similar love for BMW M cars. The owner of this Austin Yellow M4 has at one point in his life owned without exception every single M car ever created by BMW, and his sense of perspective has enabled him to work with brands that have stood the test of time- BBS, Brembo, Eisenmann.

Our client’s M4 is still in its early stages of modification, but is currently outfitted with a BMW Performance front lip and rear diffuser, and a BMW Performance trunk spoiler. This week we have proudly added one of the first Eisenmann exhaust systems in the country, to give this M4 the bark and personality it deserves.

Enjoy the photos, and stay tuned for more updates as this M4 project continues to develop!
