Coilovers?

[Racing Rice]

Coilovers are threaded to allow for up and down adjustment. This is good for ground clearance, corner balancing, and looks.

There are 2 types of coilovers.

True coilovers, where the shock body is threaded, and coilover sleeves that slide over conventional shocks. True coilovers tend to work much better then "sleeves" because you dont have to worry about the spring rates of the sleeves not working with the dampening rates on the shocks.

Ground Control (coilover sleeve) allows you to choose spring rates for thier kits, which is good aslong as you know what you want. Or you have a shocked revalved for a specific application.
