I found a good deal for a set of Ground Controls off a 2000 SI along with tokiko illuminas. However my car is a 1999 Civic EX and I know that the spring rates are different but I was wondering what effects would it have on my car if I were to install the GC and the shocks made for an SI. The thing im worried about is my car being bouncy as a mofo so can anyone help me out here?

Thanks yall
