SPC Camber Bolt Issue - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

breadcrumbz · 01-26-2015, 07:36 PM

I recently installed the SPC 81305 camber bolt. I installed the bolt on the bottom mounting point on the strut, just as the instructions stated. After getting an alignment, the technician stated that he could only achieve -0.4 and -0.7 maximum camber when I wanted -1.5 on both sides.

He stated that if I used the camber bolt on the upper mounting hole, I can get more adjustment. Would it be possible to use this bolt on the top instead? I want to get more negative camber, but do so safely.

This is the exact same one that I purchased.

It is supposed to be in the top.

Not true. Spc instructions say bottom for that particular part number. And the instructions also say "frs/brz".

From what I know, people usually use 14mm on bottom and 16mm or subaru/toyota crash bolts on top. I say you just get another set for the top holes.

It's better on top. The camber I mean

swarb · 01-26-2015, 08:30 PM

I have also read people used two sets of the same bolts on top and bottom.

Speed Element · 01-26-2015, 08:51 PM

Its suggested to put it at the bottom.

Take the lower hole bolt that was removed and use it in the upper slot. It is the OEM crash bolt. I can get -2.5 with this setup on a 1" drop.

while i used camber bolts on both holes with no problems, keep in mind your not effectively running 2 weaker bolts rather that one if you choose to do that.

This.

Setting camber isn't always "what I want" but rather "what the adjustment methods will physically allow."

I'm also running exactly the set-up @finch1750 mentioned and have it dialed it in -1.7 both sides on the front. Could have probably pushed it a bit more to -2.0 with another set of hands.

So you guys are saying its completely safe to use a 14mm bolt in a 16mm slot?

Yes, a plain 14mm bolt. This is called a "crash bolt" and is the OEM camber adjustment part. You can buy them from the dealer but you just get the same bolt you pulled from the lower mounting hole. If you use a 14mm lobed bolt like SPC in a 16mm hole the chances the bolt will slip are pretty high.

to the OP, just wondering if your technician loosen the upper bolt while adjusting the camber.
