After adding all the power you can to your S2000, you'll have to find a way to transfer that to the ground. And, the only way once can achieve this is by selecting the correct coilovers for their car, meaning coilovers that have a softer spring rate up front, and a stiffer spring rate in the back. The reason this is, is because when you attempt to transfer a lot of horse power to the ground, your car's suspension might not be able to handle it, which causes both wheel spin, and fishtailing of the rear end of your car when launching. By upgrading to a better coilover system than the OEM one, you can eliminate most problems with translating power to the ground.
And for those who are looking to Slam their cars, coilovers will allow for you to get the maximum drop wanted, while still providing a comfortable ride, as long as you tune the dampening properly.
The coilovers below are some of the best ones on the market for your S2000. Whatever you choose as your coilover set up, you will not be let down!
