Lowering the ride height of your 08-10 Evo X is can be a very effective modification, enhancing handling by creating a lower 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 changes too, which can make your car handle worse than stock when you are trying to carve out those deep corners. The Mitsubishi Evo X is especially prone to this when lowering springs are installed due to the way stock suspension geometry was designed. In many cases the roll-center is actually moved to below pavement level.
The suspension gurus at Whiteline have developed the perfect cure to this ailment: The Whiteline Roll-Center Kit, also known as a ROCK Kit . The Whiteline ROCK kit realigns the suspension geometry of your lowered Evo X, 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. While it may not sound important, the advantages to this theory are drastic. 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. A great modification for a stock Evo X, but an absolute must if your Evo is running with a lowered ride height.
