Sharpen Front-End Feel on Your E46
The factory rubber front control arm bushing on the E46 chassis softens with age, letting the control arm shift under load and dulling steering feedback and braking stability. The Whiteline W52605 front control arm lower inner rear bushing kit (66mm OD) replaces that worn rubber with a synthetic elastomer bushing, restoring precise control arm location for sharper turn-in and more predictable braking behavior.
Key Features
- Synthetic elastomer bushing restores precise front control arm location
- Improves steering feedback and braking stability lost to worn rubber
- Superior elasticity and memory compared to factory rubber
- Direct bolt-in replacement for the lower inner rear control arm mount
- Backed by a Whiteline Limited Lifetime Warranty
