you dont want to keep the stock shocks with lowered springs. you can, but the shocks will wear out a lot faster. so you would inevitably have to replace them. thus costing you a 2nd installation charge. might as well do it all at once and save some cash.
If you are interested in the Eibach/Koni set up.... contact Gavin@MMW. I bought my set up from him and it has been great. Plus, he is the man. one of the best mods I have ever done to my car. Makes it a lot more fun to drive. and looks good, especially with my Avant Garde's....that Gavin also hooked me up with.
