Can somebody recommend a shop to get lowering springs installed in LA or Orange County, California. Most shops I called would not guarantee work on aftermarket parts. I'm still deciding between H&R and MaxSpeed, but I need to find a reputable shop to do the work first.

 

What kind of gaurantee are you expecting?

There are several options but you should expect to pay $150-$200 for the job...if you have the $$$ to burn, just go to the dealer.
