kickass Jason, thanks again for your info. This is the setup I'm planning to do if you are curious:
Stock XI Struts/shocks and Springs
15mm front drop hats/5mm lower rear spring pad.
Standard XI Suspension vs Standard I Suspension Height:
23.85in vs 23.19in (Front) = .67 inches difference
22.52in vs 21.85mm (Rear) = .67 inches difference
Custom Stock XI Suspension vs Standard I Suspension Height (Projected):
23.26 vs 23.19in = .1 inch difference
21.93 vs 21.85in = .1 inch difference
so there you have it. it is going to be as close to I specs as possible without having to shell out a whole lot of money (aside from the stock parts)
