You will need to transfer the stock tops of the old shocks to mount the H&Rs. I had to buy them because I went BC Coilovers and left the stockers w the guy who swapped them out. The swaybar bushings on my BMRs do not have grease nipples and the ones on the front won't hold a fitting worth squat. I have to take off the links and grease them both by hand. You should expect a good ride from these coilovers. I had a shattered bearing (MI Pothole) from running the overwound and poorly damped BC's and it wasn't spotted by the installer until I found it. If you do the body inserts expect more road noise. Of course you will be getting an alignment. I raised the back to near min drop to avoid rubbing even after I got the fenders rolled for my 275s. Move on knowing that many cars that can outrun you in the 1/4 will lose to you on a road course or the twisties. Brake upgrade is your friend.
