034Motorsport BMW E87 E88 E90 E92 Billet Aluminium Rear Subframe Mount Insert Kit
Transform the way your BMW 1 Series or 3 Series drives with the 034Motorsport Billet Aluminium Rear Subframe Mount Insert Kit. Designed for E8X and E9X chassis cars including the BMW 1M, 135i and 335i, these precision CNC machined 6061-T6 aluminium inserts fill the voids in the factory rubber rear subframe bushes to dramatically reduce subframe movement, sharpen handling and maintain proper suspension geometry under load. Expect a tighter, more connected rear end on fast road and track without adding perceivable NVH inside the cabin.
We have installed and run these rear subframe bush inserts on multiple customer E8X and E9X builds, and feedback has been consistently positive: crisper turn in, improved traction out of corners, reduced wheel hop and more predictable behaviour at the limit. This is a must-have BMW handling upgrade for anyone chasing stability, confidence and response.
Why upgrade your BMW rear subframe bushes
- Reduces rear subframe movement during launches, acceleration and hard cornering
- Keeps alignment and suspension geometry stable for repeatable grip and tyre contact
- Improves rear-end stability, turn-in precision and differential response
- Enhances the effectiveness of uprated rear anti-roll bars and performance suspension
