BMW E90 Competition Lock Kit DXC

DXC Racing Angle Kit – 50% more steering lock and perfect geometry

The DXC Racing angle kit is a proprietary design engineered for maximum precision, stability, and performance. It increases steering angle by up to 50% while maintaining a compact layout and precise fitment within the wheel arch. The geometry has been optimized for perfect control and allows installation without cutting the bodywork or using fender flares (depending on wheel size).

The setup delivers sharp, aggressive handling – the car pushes forward confidently and remains stable at high steering angles without self-steering. Proven on track, this configuration secured the 2025 Slovak Drift Championship title and multiple podiums across Polish drifting leagues.
