Camber Bolts

Looking at running some negative camber up front come summer. What options are out there and which will get me the most aggressive camber? Looking for around -5 degrees if possible.

Thanks.

I don't have much experience with camber bolts but iirc each bolt only gets you roughly 1° , and you can only use 2. May have to look into an adjustable top hat from Cusco(or equivalent) to get the 5° you're after.

I run the TRD Camber bolts. Think the max you can get is just under 3*. If you want more, you may need to elongate the camber bolt hole in the strut. I don't recommend doing this. Maybe some more research out there will help. A lot of the camber bolts are interchangeable between toyota cars with same designs.

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.

Good to know they don't slip (except when stuffing it ).
Odd. I got -2.8° out of just one bolt on my 09 5dr (and shifting subframe/ctrl arms).

Cheers.

Your end number may have been -2.8, but it did not come as the result of a single bolt. The alignment starting point, moving items (as you mentioned) and ride height changes also impact the final number.

I did not stuff it, a CRX tried to ride shotgun. Watch from the 46min mark: http://www.scca.com/videos/1972492
