Precision CNC-machined from high-strength aluminum for exceptional strength and durability.
Pre-preg carbon fiber construction.
For best results, installation by a qualified technician is advised.

The Slon Workshop E46 M3 Carbon Front Triangulating Reinforcement Kit is a comprehensive chassis reinforcement system engineered to significantly increase front-end torsional rigidity while maintaining serviceability and minimizing weight. Developed specifically for the BMW E46 M3, the kit replaces the factory strut brace with a true triangulated design that ties the front suspension towers directly into the chassis, resulting in measurable improvements in structural stiffness.

Extensive development and back-to-back testing demonstrated an 18-20% increase in torsional rigidity compared to the factory strut brace. For reference, the OEM brace provides only approximately a 1.5% improvement over a vehicle without a strut brace. By creating a rigid triangulated load path between the strut towers and chassis, the system improves chassis response while maintaining an OEM-quality installation.

Constructed from prepreg carbon fiber and CNC-machined aircraft-grade aluminum, every component has been optimized to achieve an exceptional stiffness-to-weight ratio. Despite adding significant structural reinforcement, the complete kit weighs only 3.1 kg (6.8 lbs), replacing factory components totaling 5.6 kg (12.3 lbs) for an overall reduction in weight.

Unlike many reinforcement systems, the Slon Workshop kit was engineered for installation without welding, cutting, or drilling. A modular intermediate center bracket allows the carbon strut brace to be removed independently for routine engine service while the structural center mount remains permanently bonded to the chassis.
