Lowering the ride height of your 03-06 Evolution is 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 Mitsubishi Evolution is especially prone to this effect due to exact tolerances in which the stock suspension geometry was designed, in many cases realigning the stock suspension so that the roll-center is actually below pavement level. The suspension gurus at Whiteline have developed the perfect cure to this ailment, the Whiteline roll-center kit. The Whiteline roll-center kit realigns the suspension geometry of your lowered Evo, 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 like much, the advantages to this theory are drastic.
The Whiteline ROCK kit for the 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.
