Whiteline Roll-Center & Bump-Steer Kit WRX 02-21 / STI 04-21 / Legacy GT / Outback XT 05-09 | KCA313

Part #: KCA313. Lowering your Subaru WRX or STI is a great way to enhance handling and give your car a cool look. But it can mess up the front - end roll - center, making your car handle poorly in corners. Whiteline's roll - center kit, also known as the ROCK kit, is the answer. It realigns your lowered Subaru's suspension geometry, raising the front roll - center. This boosts front roll resistance, cuts down suspension compression on the outside front wheels when cornering, improves front - end weight distribution, keeps a better camber angle, and gives you better front - end grip. You'll also feel less understeer and enjoy improved steering feel, precision, and overall stability. Another issue with lowering your car is bump - steer, where road bumps make your car steer off - track without you doing anything. This is due to poor suspension geometry when the car is below factory specs. Whiteline's bump - steer correction kit extends the factory front - end tie - rods, keeping the axles at a consistent distance from the frame at the steering box. This gets rid of axle tilt and cures bump - steer. Every Subaru roll - center kit comes with the bump - steer kit for a complete suspension solution. Your Subaru will feel amazing!

Using the Whiteline roll - center and bump - steer kit is straightforward. First, make sure your car is on a flat and stable surface. Follow the included instructions to install the roll - center kit, which will realign your suspension geometry. Then, install the bump - steer correction kit by extending the front - end tie - rods as described. As for maintenance, check the kit regularly for any signs of wear or damage, like loose bolts or worn - out parts. If you notice anything wrong, replace the parts right away. When driving, keep in mind that this kit improves handling, but you still need to drive safely. Don't push your car too hard in extreme conditions. And always follow local driving laws. Enjoy a better driving experience with your upgraded Subaru!
