Lock in your BMW’s rear-end stability and enjoy razor-sharp confidence

Tired of rear tracking that will not stay put under hard cornering, bumps or acceleration? This RTAB limiter kit is the proven fix. By controlling lateral movement at the rear axle, these precision Delrin inserts support the rubber RTAB and keep rear wheel alignment consistent. The result is steadier handling, reduced rear steer effect, and better tyre wear without introducing noise, vibration or harshness.

Made in the USA from wear-resistant Delrin acetal, this 4-piece kit surrounds the rubber bush to prevent excessive side load while extending bush lifespan. Ideal for spirited road use, track days and fast-road builds, it is a simple, high-impact suspension upgrade for BMW E36, E46, E85 and E86 platforms as well as selected E83 X3 models.

Why enthusiasts choose this upgrade

  • Alignment control under load for consistent rear tracking and predictable turn-in
  • Helps curb uneven tyre wear caused by rear wheel toe shift
  • No noticeable increase in NVH compared with stock rubber bushes
  • Durable Delrin construction for long service life
  • Perfect for street, fast road and occasional circuit use
  • 4-piece kit. One kit required per vehicle

Real-world proven at MJ Modifications

We run these on our own builds and customer cars because they simply work. Improved stability, cleaner alignment readings and happier drivers. It is a small part that makes a big difference to confidence behind the wheel.
