As you know, the stock E30, E21, E28, E32, and E34 rear subframes do not allow you to align the rear wheels. You also know that alignment is a critical point in spec E30 as well as any track, autocross, or spiritedly driven car. So you do what racers have done for years, and is common practice. You purchase camber/toe brackets and get them welded to the rear subframe on the rear control arm mounting points. You slot the original hole and have these professionally welded in place. You are now able to align your car using the common E39 eccentric hardware or Garagistic Eccentric hardware! Well, what most people end up finding out at this point is that racing any car will knock the alignment out of place because of the demands of racing and road conditions.
We experienced this firsthand as well. So we came up with a solution that would be able to be used for people who have already modified their subframe with the "industry standard" camber/toe brackets that originally use the E39 eccentric hardware or our Garagistic eccentric hardware.
Introducing the Quick alignment shim system
What we made was a system of 1mm shims that will allow you to set your alignment and forget it. Never again needing to align your BMW or worry about it coming out of alignment. You will not have the fine adjustment of the eccentric hardware, however you will be able to put the needed shims on each side and, by using different shims, get alignment to where you want it and where it can stay!
Again, this is for people who have already done the camber/toe bracket modifications or bought our adjustable subframes found here.
Please note, we only guarantee fitment with OUR camber toe brackets which are machined out of a billet piece of steel. Although they should work with any kit that used the E39 eccentrics, we do not hold our products to other people's tolerance or "bent sheet" metal variations of the camber/toe bracket.
Compatibility
-
Fits: Can be used for BMW E21, E28, E30, E32, E34, E36 318ti, and Z3 who have adjustable subframes.
-
Please Note: These will not work for subframes that have been modified.
Included
WHAT'S INCLUDED AND WHICH KIT DO I NEED?
Each "kit" includes 4 shims per camber bracket on your subframe. This is enough to do BOTH camber AND toe adjustment. The subframe has 4 mounting points for the rear trailing arm, 2 per side or 8 mounting points. So you will have the ability to use 1 of your 4 shims in each of these mounting points to get the alignment you require.
HARDWARE INFO
These are meant to replace the common BMW OEM E39 Eccentric Bolts, Eccentric Washers, and Bolts that are used to make your E30 or similar subframe adjustable. It also will replace Garagistic eccentric hardware. That hardware it replaces is:
