Roll Center/Bump Steer Correction Kit

A must for lowered vehicles, Whiteline roll center and bump steer correction kits are designed to correct roll-center geometry using specially engineered ball-joints and tie rod ends. Raising the front roll-center results in a substantial increase to front roll resistance and a significant reduction in suspension compression of the outside front wheel during cornering. The result is more even weight distribution and improved tire contact ultimately improving front end grip and cornering speeds.

Great quality!

Installed these on my 2013 WRX hatchback.
Parts fit perfectly and they look awesome can’t go wrong with Black and Yellow! Installation is on point and easy. If I didn’t live in the northeast it would’ve been way quicker to swap but you know… RUST! LOL

Pretty good stuff but the install is a pain

These fixed my steering problem with this kit, the tie rod ends are super easy to install if your car isn’t rusty. But the ball joints are absolutely horrible. Get a specialty tool to take them out and install. The quality on these is super good though, my car feels so smooth

Whiteline Bump steer correction kit.

Ordered this for my 04 JDM STi v8 Blobeye. Shipping to my courier services was fast (about 3 working days) but since the covid situation, I just received them today. The package was good. Thank you to team MAperformance for the help.
