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. It lowers the center of gravity, giving your car a more aggressive look by reducing wheel gap. But, when you change the stock ride height, the front - end roll - center gets modified. This can make your car handle worse around sharp corners. Whiteline's roll - center kit, also known as the ROCK kit, is the ideal solution. It realigns the suspension geometry of your lowered Subaru. By raising the front roll - center, it significantly boosts front roll resistance and reduces suspension compression on the outside front wheels during cornering. This kit improves front - end weight distribution, maintains a better camber angle, and greatly enhances front - end grip. You'll also notice less understeer, along with improved steering feel, precision, and overall vehicle stability. Another issue with lowering your car is bump - steer. Bump - steer happens when road bumps or imperfections make your car steer off - track without driver input. Many Subaru drivers find they need to constantly correct the steering on bumpy roads. This annoying and sometimes dangerous problem is due to poor suspension geometry when the vehicle is lowered below factory specs. Whiteline's bump - steer correction kit extends the factory front - end tie - rods. It keeps the axles at a nearly constant distance from the frame at the steering box, eliminating axle tilt and curing bump - steer. Every Subaru roll - center kit from Whiteline includes the bump - steer kit, offering a perfect total suspension solution. Your Subaru will feel better than ever!

Using the Whiteline Roll - Center and Bump - Steer Kit is straightforward. First, make sure your car is on a flat and stable surface. You'll need basic mechanical tools to install the kit. Start by following the included instructions to remove the relevant parts of your existing suspension system. Then, carefully install the new components of the roll - center and bump - steer kit. Make sure all bolts are tightened properly. As for maintenance, it's a good idea to check the kit regularly, say every few months or after a long drive. Look for any signs of wear, like loose bolts or damaged parts. If you notice anything unusual, it's best to get it checked by a professional. When driving, be aware that the handling of your car has changed for the better. But always drive safely and adjust your driving style according to the road conditions. This kit is designed to last, but proper care will ensure it keeps performing at its best for a long time.
