From my rough estimation, 1mm of slotting should get about 0.88 degrees of camber.

But, the holes on the BC coilovers may be slotted already plus don't they come with camber plates?

[SLICVIC]

it looks like they are a little slotted but in the case that i want moar camber

[OrbitalEllipses]

So do the Impreza bolts (#20540AA090) work?

[xwd]

No they don't. You'll want the crash bolt or one of the bolts from H&R/Whiteline.

The Subaru PN for the crash bolt is 901000394.

Lots of good info in this thread, thanks to everyone who posted so far.

I won a Whiteline Gift Cert/Discount Cert at the 86fest and am trying to figure out how to leverage it to get my car dialed in.

At this point the suspension is bone stock. From what I've read and heard, I really need to add some neg camber for my newfound love of AutoX.

I'm thinking of getting both the camber bolts (Whiteline PN KCA416) and the COM C (Whiteline PN KCA 335). I also want to swap out the springs to RCE or Hotchkis springs.

Is it a good idea to get both the camber bolts and the COM Cs if I plan to swap in some better springs later?

I know Coil-Overs would be better, but the budget won't allow for them for some time.

The way I understand it, the COM Cs can add about of 1 degree of neg camber, while the bolts offer about 1.5 degrees. So you can do some math and figure out how much camber you want

here's the video from whiteline explaining them:

Not exactly, the bolts offer .75+/- not 1.5 degrees negative.

You get the idea. The Com C offers some, and the bolts offer some, so they could be tuned to get a specified amount.

just curious, why don't the good ones include camber plates or top mounts?

[gmookher]

KCA416 is correct

should be available from anyone that carries whiteline. I'll have to check and see if WL US has any in stock. Actually Eibach/SPC/ingalls should have one that size for much less. Try 81280

whiteline recommends the KCA416 (16mm) for the brz/frs. the instructions state to install it in the top hole. however, you can also install it on the bottom hole but it's recommended for race application only.

see instructions:
http://www.whiteline.com.au/docs/ins...ides/Z201A.pdf

what would be the difference installing it at the top vs at the bottom? my guess is that the bottom allows for even more negative camber but will increase tire wear on the outside shoulder of the tire, which is why they recommend it for race application only.

please feel free to shed some light on this.

Higher end coilovers don't included top mounts for a couple of reasons. First, their coilover manufacturers, not camber plate manufacturers. They focus on what they do best. It's also helpful to have it as an option from the venodr. Many people already have camber plates they want to run OR they don't want to run camber plates at all and run the stock mounts. Also, it might be done for european TUV certification but I'm not sure on that.

Ohlins is an exception. They include top mounts for their R&T coilovers and those are "good."

Most of the top mounts included in the lower end coilovers aren't very good and are a common area of failure and noise.

hey andrew,

i think you guys have the sti rear lower control arm on your brz. do you know if that's adjustable and will allow some negative camber in the rear?

[Racecomp Engineering]

The STI arm is not adjustable. We are using the Whiteline rear camber adjustment at the moment.
