My plans for coil over set are the TODA Fightex system. You name you spring rates. Get the total, front, and rear weights of your car. withthe spring rates, and weights they can valve your struts. struts are adjustable both bound and rebound. Totally rebuildable and tunable. Only problem, PRICE, BIG PRICE, nearing $2000 mark. Other than that, there are some out there available under $1000. Then you have Ground Control sets. $400 gets you sleeves, and springs at the rates you choose. I have these on my 2 at front rate of 300lbin and rear rate of 650lbin. Then you buy the struts of your choosing, mine are Koni. Either way you go, $1000-$2000 for struts. Oh yeah, you adjustable shocks are a LOT harder to hide than a new set of nonadjustabe inserts. I do like a chalenge though.
