Upgrade your rear suspension setup with this premium DTM-style trailing arm adjustment kit. Engineered with precision, this kit replaces the standard fixed or loosely adjustable arms with fully modular, welded-in units capable of fine-tuning camber, toe and ride height precisely. By welding the kit into place, you create a stiff, reliable mounting platform that holds alignment consistently under load, brake dive and high cornering forces. Ideal for drivers who demand uncompromised control, responsiveness and the ability to dial in their rear geometry for drifting, track days or aggressive street setups.
With this kit installed you’ll experience clearer feedback through the chassis, better rotation and more predictable rear-end behaviour – especially during transitions, throttle steering and heavy deceleration.
Compatible with BMW E30, E36/5, E36/7 and E36/8 models.
Kit Includes
Adjustable trailing arm assemblies (left + right) configured for DTM-style mounting
Threaded adjustment bodies enabling camber and toe correction
High-strength hardware (lock nuts, washers, and retention devices)
Left-hand M18 × 1.5 threaded interface (as specified)
Spherical bearing housings (14/29mm diameter) ready for spherical inserts (may come without bearings depending on version)
Optional: bearing set (check version)
Key Benefits
- Allows you to precisely dial in rear toe, camber and ride height geometry to suit your build or driving style (e.g., drift, track, street)
- By welding the adjustable arms, you significantly reduce flex and movement under load, giving a far more consistent rear platform under braking, cornering and throttle transitions
- The stiffer rear geometry and adjustability mean the car behaves more predictably, enabling you to exploit its dynamics rather than fight them
- Built to handle aggressive driving, heavy lateral loads and repeated high-stress situations found on track or in drift conditions
- This kit is designed specifically for BMW E30, E36/7 and E36/8 platforms, so the upgrade fits these models while offering superior flexibility and strength compared with standard trailing arms
Important Notes
Installation requires welding: This kit is for competent fabricators or workshops with welding capability. Incorrect welding or alignment can compromise safety and performance.
Geometry baseline: Before welding and adjusting ARMs, capture your factory geometry (camber, toe, ride height) to ensure you can set your starting point accurately.
Check local regulations: Custom welded suspension components may affect road legality in some regions — ensure your installation complies with local inspection requirements.
Post-installation alignment required: Once welded and installed, a full rear alignment is essential to ensure the adjustments are set correctly and the car tracks true.
