Front Camber Bolts?

It has popped up on occasion on the forum, never ran two sets myself to have first hand experiance though. Not saying it will happen for sure but like @JSimon777 said just check them every so often.

Get the 16mm SPC bolt for the top if you want to run 2 eccentrics. Or get 81305 for the bottom and put the OEM bottom bolt in the top to get more adjustment.


I'll see if I can find the 16mm SPC part number and update my adjustable suspension FAQ and link back here later.


Edit: http://www.ft86club.com/forums/showthread.php?t=103609 has the part numbers for both the 14mm and 16mm SPC bolts in the first post now

I just did the 14mm lower and OEM bolt up top and have decided against having that much camber. Id like to use the 16mm up top instead before I get the alignment but I'm feeling lazy after all that tinkering. How much more risk is there running the bolt swap vs just using the 16mm upper camber bolt as intended?

Imho relocated oem vs 16mm camberbolt (which still is actually thinner bolt just with extra lobe) is of somewhat same "risk" of reduced sheering/torquing strength. If one minds increased risks that much, then just use one set of camberbolts (which will limit max dialable neg. camber to -1.5) with other bolt left stock. If more is needed, then one needs another camberbolt set or camberplates (which cost much more).

This was my thought process as well, but of course an "off" or a pothole could throw off any alignment, regardless if the car has any camber bolts.

But candidly I'm surprised more people aren't using the two camber solution on the forums. It's a fraction of the cost of camber plates, and I'm getting close to 3 degrees (3.1 after lowered)!

It's worth mentioning, the camber bolt solution can cause issues depending on your tire and wheel setup.

I have RCE yellow springs and 17x9 et42, 245/40/17 wheels/tires and camber bolts only allowed about -0.3 degrees before interference with the springs.

Jamestl: probably due lowering it worked for you. I was limited on stock height to about -2.35 with camberbolts in both holes (KCA416+SPC 81305). Those that are set on track oriented alignment need -3 or slightly more, and camberbolts alone won't give that. "Normal" people daily driving only don't need that much camber, so usually single camberbolt set is sufficient for them. Most common option for track people are camberplates. I got -3 with two camberbolt sets and powerflex PFF69-801G bushings. There is also option of slotting bolt holes, but it has least trust in my eyes.

Yeah I got 2.7 on stock suspension and an additional 0.4 when I got struts and springs
