Turn your BMW E90 Sedan into a dedicated apex-hunter with this Professional Tracktool Bausatz. Specifically curated for the “Nürburgring-spec” enthusiast, this kit focuses on extreme weight reduction, structural rigidity, and high-speed aerodynamics. By replacing heavy factory panels with high-grade carbon fiber and reinforcing the chassis with a Wiechers Sport safety cell, this package provides the foundation for a competitive WTCC-style or endurance racer.
Included Components (Track-Ready Package):
-
Wiechers Sport Roll Cage: Full Bolt-in or Weld-in (CrMo4 or Steel) safety cell, FIA/DMSB certified. Includes door bars and H-strut.
-
Carbon Fiber Bodykit: * Lightweight Carbon Fiber Hood (GTR-style venting).
-
Carbon Fiber Trunk Lid (CSL-style integrated ducktail or flat for wing mounting).
-
Wide-Body Fenders (Front & Rear) for increased track width.
-
-
Aerodynamic Package:
-
Adjustable Carbon Fiber Rear Wing (GT-Spec).
-
Front Splitter with underbody tray and tension rods.
-
Rear Diffuser optimized for center-exit or quad exhaust.
-
-
Polycarbonate (Lexan) Window Set: Full side and rear window replacement (anti-scratch coated).
Specifications:
-
Model Compatibility: BMW 3 Series E90 Sedan (2005–2012).
-
Target Build: Trackday / Ringtool / VLN / RCN Racing.
-
Weight Reduction: Estimated -45kg to -70kg (depending on interior stripping).
-
Material: 2×2 Twill Vacuum-Infused Carbon Fiber & High-Strength Steel/Chromoly.
-
Safety Standards: FIA / DMSB / TÜV (Material certification included).
-
Finish: Gloss Carbon Fiber (UV-protected) or Primed for Racing Livery.
Vehicle Compatibility:
-
BMW E90: 320si (WTCC Base), 325i, 330i, 335i, M3.
-
Note: Ideal for N54/N55/S65 builds requiring extra cooling and aerodynamic downforce.
Features:
-
Wiechers Structural Rigidity: The included roll cage significantly reduces chassis flex, allowing the suspension (e.g., KW Competition or Bilstein) to work more precisely under high G-loads.
-
Advanced Thermal Management: The GTR-style carbon hood features functional louvers to extract heat from the engine bay, critical for turbocharged 335i “Ring” laps.
-
Optimized Downforce: The GT-spec rear wing and front splitter are wind-tunnel tested to balance the E90’s aero-map, ensuring high-speed stability through sections like Schwedenkreuz.
-
Weight-to-Power Optimization: Replacing steel panels with carbon fiber lowers the center of gravity, drastically improving turn-in response and braking distances.
-
Brake Cooling Integration: The front bumper is pre-ducted for 76mm cooling hoses, directly targeting the front calipers to prevent fade during endurance sessions.
