Description
Adjustable rear upper longitudinal control arm pair designed for BMW E8x (1-series) and E9x (3-series) models. These arms are developed to replace the original flexible control arms, providing significantly firmer support and eliminating unwanted rear suspension deflection under high cornering loads.
The arms are manufactured from high-strength 4130 Chromoly (25CroMo4) tubing and TIG-welded for maximum durability. The in-situ adjustable design (double adjuster) enables quick and accurate fine-tuning of the suspension geometry without the need to remove the arms from the vehicle. The kit includes all necessary reduction bushings for a direct bolt-on installation into OEM mounting points.

- Design: Optimized for motorsport, featuring a lightweight and high-strength 4130 Chromoly structure.
- Material: 4130 Chromoly (25CroMo4) steel, TIG-welded.
