The BTS kit is not a coil over kit. I would stick with the tried and true companies for coil overs. Best way to do this... head out to your local autoX and ask some of the faster guys what suspension they run. I run Ground Control on the wagon and will probably do the same on Project 330ti. I hear and see great things out of TC Klein's stuff too. The PSS and PSS9 kits are very much a street system. The springs are progressive rate, but they are both great compromise kits. __________________ SUPPORT 318ti.org! CLICK THE LINK ABOVE!
