Camber Bolts

[Jason@SportsCar]

A pair of SPC bolts (upper and lower hole) should be good for around -4 if you have lowered your car some. Much of anything over -3 to -3.5 is excessive and doesn't do much for you unless you are in to that "look".

I'm guessing you've never tried two? I'm just curious if two skinny bolts would handle track-days or not. It's general considered unsafe to have two skinny bolts in there.

One SPC bolt will give -2.8° btw. I can't see needing any more than that for performance.

I currently run a pair of SPC bolts in each strut, a single bolt will not give you -2.8... A single bolt has a range of +1.5 to -1.5 (that is from zero), it requires two to get more. I have never had them slip in normal use.

When we first built the B-Spec cars we used two of the smallest OE crash bolts in each strut, was good for about -2, never slipped.

Even with this hit, which broke the wheel, the bolts did not fail - although they did slip, so I replaced them, along with the control arm, spindle, axle, ect.
