Whiteline is in the business of activating grip. Through the use of their products, you can tailor your vehicle for race oriented activities versus everyday normal driving.

The KCA313 is designed to raise the front roll-centre geometry by using specially engineered ball-joints & tie rod ends while still maintaining original steering geometry. Front roll geometry actually encourages roll the lower you go. Testing proves that raising the front roll-centre resulted in a substantial increase to front roll resistance & a significant reduction in suspension compression of the outside front wheel during cornering (less roll). This improves weight distribution & maintains a better camber angle which ultimately improves front grip. The overall outcome is significantly reduced understeer through reduced front wheel compression as well as improved steering precision & vehicle stability.

  1. Great fit, and easy install w/C23 Tool

    By Davep January 5, 2022

    Use the Company 23 ball joint tool, and save yourself a ton of time and work! I did one side before I received the tool, and it was a pain. But with the tool, it was maybe 10 minutes before I was reinstalling the new ball joint. Installed this kit on my 18WRX (50k miles) with a mostly Whiteline suspension and even without more than a tape measure alignment so far, bumpsteer and overall feel is already much improved. Had to put my winters on, so even after the full alignment, I won't be able to really push it through corners until the summers go back on but overall happy so far. Now to get some miles on em.
