To all south cali residents,
can anyone recommend me good place that would do a good job in apex coilover installation? thanks

 

Any tuner shop that lowers cars can intall it for you. It's not that much more different than changing out to performance springs and shocks. The only difference is that once installed, you need to spend some time adjusting the height on all four corners to the drop that you want.

Sorry I don't have any shops in mind, I don't trust anybody to touch my car . . . that's why I do most of my own work.
