Getting Aligned
1 Attachment(s)
So recently I put a set of Bilstein pss9's on my r53. I went to Goodyear to get an alignment without camber plates or rear control arms knowing that they wouldn't be able to get the camber and toe within spec. They did there best regardless. Later I did some research and came up with that the rear lower control arms will allow for better toe adjustment by adjusting at the trailing arm mount. Is this right? My rear toe is the biggest concern. I just want to go in there for my alignment with the plates and control arms better informed. There seemed like a lot of confusion between the mechanic and I.:rolleyes: I'm going with Vorshlag camber plates and H-sport lower control arms for reference.

Also, does anybody know the bilstein upper spring perch size?:confused: The option list asks for 60mm, 2.5in, or oem.

My before and after alignment sheet is attached.

Thanks guys,

supposed to be the trailing arm bushing bracket for rear toe adjustment.

A lot of good information there, thanks. They told me they couldn't adjust toe because I had stock control arms. I'll let them know its done otherwise

tell them it's done the same way bmw 3 series trailing arms are adjusted.

Sounds like they are confused. Adjusting the camber is done with the control arms. The toe is seperate

Adjusting the toe on a stock configuration is done using the 3 bolts at the front of the trailing arm (where it attaches to the body). They are rather tricky to spot and I think one of the bolts is accessed through a hole/flap in the side skirt. They bolt in vertically from the bottom up.

The lower rear control arm has a concentric bolt which attaches to the trailing arm. This is primarily used to adjust camber but it will tweak the toe extremely slightly.

Upper control arm is fixed with no adjustability.

If you have adjustable lower and upper rear control arms you can adjust both toe and camber.

Thanks guys this is the information I was looking for. When I go in this weekend for a re-alignment I'll have a little bit more knowledge on the subject in case we aren't on the same page. From what they told me, and the looks of the sheet, they may not know about the toe adjustment on the mini. If all fails I can go elsewhere
