Lowering the ride height of your Subaru WRX and STI can be a very effective modification, enhancing handling by creating a lower vehicle center of gravity and giving the car an aggressive look by minimizing wheel gap. Unfortunately, once the stock ride height has been altered, the front end roll-center is modified as well, which can actually make your car handle worse than stock when carving out those deep corners. The suspension gurus at Whiteline have developed the perfect cure to this ailment, the Whiteline roll-center kit. The Whiteline roll-center kit, also called the ROCK kit, realigns the suspension geometry of your lowered Subaru, raising the front roll-center and creating a substantial increase in front roll resistance and a significant reduction in suspension compression on the outside of the front wheels during cornering. The Whiteline ROCK kit will improve front end weight distribution, maintain a better camber angle and ultimately improve front end grip. You will also experience a reduction in understeer as well as improved steering feel, precision and overall vehicle stability.
Another negative side effect of lowering your car can be the induction of bump-steer. Bump-steer is the concept of bumps or imperfections in the road causing a car to steer off-track on its own, without any driver input. This is described by many Subaru drivers as needing constant direction correction when steering over a bump. This annoying and sometimes even dangerous effect is the result of poor suspension geometry when a vehicle is lowered below factory specs. The Whiteline bump-steer correction kit extends the factory front end tie-rods to keep the axles at nearly the same distance from the frame at the steering box, eliminating axle tilt and subsequently curing bump-steer. Whiteline includes their bump-steer kit in every Subaru roll-center kit for the perfect total suspension solution. Your Subaru never felt this good!
The quality of the parts and packaging make this stand out. Only way it would be better is if whiteline included stickers with it, which I was disappointed they did not. Otherwise 5/5
Quality seems pretty good but we'll see how they perform once its installed
Good quality product, fast and easy shipping. IIR always comes through
If you’ve never replaced your ball joints it may be hard, due to the fact that the bolt that pinches the knuckle together may snap but with patience and heat and vibration it may come out. Over all I loved this product, I decked out my cat with Whiteline over hall.
I purchased these for my 2021 WRX due to reading multiple forums stating that when lowering the car, these should be purchased. I bought them and installed them at the same time as my coilovers. Unfortunately, because I went this route, I can't compare them to the OEM tie rods and ball joints with the newly installed coilovers. They seem to be doing their job though. Do yourself a favor and purchase the Subaru ball joint removal tool and rent a tie rod removal tool kit!
Feels great compared to oem. Replaced the oem stuff with these when I was swapping to a 15+ rack on my 14 Sti. Recommended! I'll try to update on longevity.
The bump steer is definitely minimized, look cooler under the car vs stock tie rods and ball joints haha.
Changing these without the company 23 tool sucks though. Your old ones are most likely rusted in. I live in the desert and even mine were still stuck in there.
Anyone that lowers their car will need this and rear control arms to keep the alignment of the car correct. Definitely recommend Whiteline products for suspension parts.
When lowering your car you’ll need this.
Installing these this weekend with a few other parts from Whiteline. Quality looks amazing!
