Ridgeline Motorsport GT4 MK2 Rear Wing (Autoclaved Pre-Preg Dry Carbon Fiber)

A 140 cm autoclaved pre-preg dry carbon fiber rear wing creating the most prominent rear profile for aggressive Clubsport and Time Attack builds. Fits E46 M3, E9X M3, F8X M3/M4, F87 M2, G87 M2, and G8X M3/M4 (adjustable mounting required — see wing mount hardware).

Installation & Care: A step-by-step guide covering bracket assembly, trunk drilling, and reinforcement sleeve installation is available on request. Professional installation is strongly recommended for any work involving trunk drilling or chassis mounting. Test-fit all components before drilling or permanently securing hardware, and don't fully tighten mounting hardware until the wing is correctly positioned and aligned. Inspect all mounting hardware before your first drive after installation, and recheck/retorque after the first drive or track session — vehicles used on track should be inspected before and after every event.
