BMW REAR SUBFRAME COMPLETE CAMBER AND TOE CORRECTION BRACKETS

The stock E30, E21, E28, E32 and E34 rear subframes does not allow you to align the rear wheels. Alignment is a critical point in spec E30 as well as any track, autocross, or spiritedly driven car. Adjusting your camber and toe is also a must when lowering your car. It's a night and day difference. When an E30, for example, is lowered, the car has a lot of negative camber (up to 6 degrees!). Although this is wanted by some, it can be excessive. These brackets are welded to the rear sub frame on the rear control arm mounting points. You slot the original hole and have these professionally welded in place. Then using either the Garagistic eccentrics or the OEM eccentric BMW hardware the rear of your BMW can be properly aligned! We also offer sub frames with this welding service completed and freshly powder coated for most BMW chassis, please see our other listings. 

Do not be fooled by inferior kits consisting of bent sheet metal tabs that are flimsy and inferior. The fitment is poor on the eccentric bolt which increases the likelihood your car will go out of alignment over time or if driven aggressively. We have had customers get their cars out of alignment in a SINGLE track event with those kits! 

Compatibility

Can be used for BMW E21, E28, E30, E32, E34, E36 318ti, and Z3. These are spec E30 legal! 

Professional installation recommended.

WELDING REQUIRED!

WHAT'S INCLUDED AND WHICH KIT DO I NEED?

Each "kit" includes 8 brackets. This is enough to do BOTH camber AND toe adjustment (This includes 8 weld on brackets and 4 OPTIONAL bolt assemblies with eccentrics, you will require eccentric hardware for proper adjustment) . The sub frame has 4 mounting points for the the rear trailing arm, 2 per side. The camber is adjusted using the inner mounts (closest to diff), and toe is adjusted with the outer mounts (closest to the wheels). The camber brackets (inner tabs) should be welded with the slots going up and down. The toe bracket (outer tabs) slots should be horizontal (front to back).

The symptoms

These brackets are a must to be able to align the rear of your classic bmw. That's especially true if you have lowered your car. Some pictures of the symptoms:

Excessive negative camber:

Parts needed:

  • Garagistic toe and camber correction kits
  • 33321095102 - Eccentric Bolt
  • 33306786186 - Eccentric Flat Washer
  • 33326760668 - Self-Locking Collar Nut
  • Subframe diffrential reinforcment (optional but a great preventative maintance while your there)

Tools

  • Electric dremel or die grinder
  • Carbide endmills
  • Tig welder (although mig works as well tig is better for this job)
  • File
  • Level
  • Clamps
  • Common sense and safety equipment

Each garagistic "kit" includes 4 brackets. This is enough to do either camber or toe. You need to order 2 kits to make the rear subframe fully adjustable for both camber AND toe. The subframe has 8 mounts (2 mounts on outside and 2 mounts on each wheel). So, to correct camber the brackets go on the inner mounts (closest to diff), and toe would go to the outer mounts (closest to the wheels). The camber brackets (inner tabs) should be welded with the slots going up and down. The toe bracket (outer tabs) slots should be horizontal.

Set initial ride height and if possible get your current alignment specs

To make sure you get the amount of correction you need we always recommend that you set your final ride height first. It is then best to go to an alignment shop and see where the camber and toe values stand the way they are. This will tell you where the brackets should go. We know that it is not always easy to go to an alignment shop for values first, but this is the ideal way to do it. These instructions and pictures will show the placment that will benefit most lowered e30s.

Camber correction

Make sure that you are putting the brackets straight. For this, we use a level. Make sure your workspace is level before you start, this will help make sure everything is 100% straight. The subframe bushing area is an excellent place to check this.

To correct camber, the brackets added to the inner trailing arm pickup points (closest to the diffrential) and must be oriented vertical (up and down). With the bottom of the slot at the original mounting hole you will get 1.25 degrees of positive camber correction. If you have your alignment spec sheet and need more than 1.25 degrees correction in the positive direction move the bracket up accordingly.

Once the plates are located in the place you want them, tack them in place. A clamp will help quite a bit here, although you could also use your eccentric hardware to hold them in place. If you are mig welding make sure to use antisplatter so nothing gets on the adjustment plane. Once tacked, remove the bolt and complete the weld. We prefer TIG welding in this process. Less mess and more precise.

We prefer to weld brackets in place before slotting. This makes it much easier in our opinion.

Picture below shows the position for 1.25 degrees positive camber correction (which is enough for most e30s).

Slotting the mounting points

This is where a die grinder and and carbide endmill will save you alot of time. Using all proper safety equipment, you can start to slot the holes. Use the brackets as a template, but try not to touch the bracket with the endmill. Patience here is key! After you're done, file down all sharp edges. Use care here.

Toe correction instructions

The toe brackets are installed in almost the same fashion as the camber kit. The major diffrence is that the bracket get centered to the existing mounting hole as pictured below.

Toe brackets are added to the outer trailing arm pickup points (closest to the wheels/subframe bushing mounting point) and must be oriented horizontally (not up and down!). Centering the hole with the slot in the bracket will get .625 degrees of toe correction in either direction. Again, this would be the time to take a look at your initial toe alignment spec sheet and adjust as needed.

The procedure here is the same as the camber brackets, once brackets are in a place you want them (and are level), tack them in place. A clamp will help quite a bit here, although you could also use your eccentric hardware to hold them in place. If you are mig welding make sure to use antisplatter so nothing gets on the adjustment plane. Once tacked, remove the bolt and complete the weld. We prefer TIG welding in this process. Less mess and more precise.

Its a good idea while your here to reinforce the mounting points on the diff mounts using our kit. They are found here:

Be sure that the metal is cleaned and prepped before welding. Below is an example of a powdercoated subframe.
