One of the most major improvements one can do to his or her car is installing a coilover kit, hands down. This Apexi N1 ExV damper kit provides a connected feeling between the ground and the driver which has unfortunately been left out from the factory. Stiffening up your suspension will allow you to carry more speed into and out of corners "in turn" resulting in faster lap times and less body roll.
The Expert Type V (ExV) is a full coilover suspension kit featuring a threaded base for precise ride height adjustment without compromising shock or spring travel. They also include a 32 way ride quality adjustment for street cars that are used at the track as well. The spring rates and internal valving of the ExV has been completely refined for excellent ride quality and sports driving.
The internal components have been specifically engineered to withstand harsher road conditions and increased wear caused by everyday street driving. The Expert Type V was developed based upon user requests for a high performance damper that doesn't carry a typical racing suspension price tag.
