Front bump steer kit replaces factory steering tie rods

Rennline front bump steer kit for selected Porsche Boxster, Cayman and 911 models.

This adjustable kit replaces the factory steering tie rod and is designed to help correct bump steer, especially on lowered vehicles. Bump steer can occur when the tie rod sits at an incorrect angle between the steering rack and hub, causing unwanted steering movement as the suspension travels.

Rennline’s adjustable design allows the arm length and tie rod angle to be fine-tuned, helping restore correct suspension geometry and improve steering precision. The kit is manufactured from 6061 aluminium and features a turnbuckle-style adjustment system for accurate setup.

Suitable for the following models:

Porsche 996
Porsche 997
Porsche 987 Boxster
Porsche 987 Cayman
Porsche 991
Porsche 981 Boxster
Porsche 981 Cayman
