i have some skunk2 coilovers right now...and im not happy with them. i want to get some lowering springs so the car will be level on all for struts. i have some skunk2 shocks...what kind of springs should i get to go along with these? and how low should i lower it? i think the legal limit on a lowered car is 23 inches. but i cant find anything on how high the factor springs are. so how many inches should i lower it to keep it legal?
