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.
