SPC / Eibach offers these tough steel adjustable Lower Control Arms.
A direct replacement for OE with no modification needed.  
 
Practically a "must have" for any E36, E46 or Z4 owner that has lowered 
suspension; with adjustable control arms you can dial in more or less camber for 
exceptional handling and performance.
Every 3 series BMW from 1992 to 2005 ends up wearing the inside of the rear tire 
before the outside, prematurely ending the life of otherwise perfectly good rear 
tires. Proper alignment is the solution: Stop wasting your rear tires and save 
yourself money!
Also, since many of our customers have lowered BMWs, they typically have too 
much camber and the factory LCAs will not allow enough adjustment, these LCAs 
can allow the proper street camber so the rear tires on your BMW to wear 
evenly... a wise investment unless you want to keep going through tires even 
faster. 
Get proper rear alignment with these adjustable rear control arms that will make your tires last and now with proper alignment; your BMW will perform at its peak.
 Sold in sets of L & R: enough for one car.
These LCAs fit:
E36 all (except compact/ Ti)
E46 
allE85/E86 Z4 all
