Lower Control Arms

Ive got steeda aluminum lca's on my car and am happy with 'em. hear lots of good things about Maximum Motorsports kits also. found mine on eBay new in box, keep an eye out and deals can be had.
 
I also like the UPR, they have every different model available as well, solid bushing, heim joint and poly....they also have the hardware kit available.

I'd use PT#2002-02 on a street car $169.00
 
I've done a lot of research on this subject. In my opinion, J&M are the best ones. They have spherical bushings to allow the rear to move a little in turns, as it was designed to from the factory. If you do some research you will find out that the ones with poly bushings don't give and can cause the rear to bind in cornering, causing twitchy steering. There rear upper & lower control arms are on my list.
 
I just went with the LRS kit for the last two cars and they worked great. Don't use the hardware kit though, it's mild steel bolts. I bought all 4 bolts, nuts and washers from a bolt store. Grade 8, hardened, $5.80 for all of it!!!

I wouldn't waste my money on expensive MM or UPR stuff unless you want to get get critical on pinion agle and you drag race a lot. If it's a street car the $159 LRS kit is all you need.
