finally got around to doing the rear camber bolt fix this weekend. Stock bolts are M10x1.25 pitch x 45mm length (seems integra's/civic's have shorter bolts) serrated (think this is the term) flange bolts. So I went out to Orchard Supply Hardware (OSH) and got 10.9 grade serrated flange bolts 50mm long, and hardened 3/8" washers. 3/8" washers fit much better than 10mm ones.

The thickness of each washer was exactly the same as a quarter, so the spec i got online was 1.75mm each washer.

----------
My last alignment had -0.8/-1.0 degrees for driver side (Before/After) and -1.4/-1.4 (before/after) passenger side for rear camber.

Assuming my camber didn't change, I used 2 bolts on the driver side and 3 on the passenger side, got it aligned and now I have -0.4 on the driver side and -0.8 on the passenger side.

so... now my question is, is it possible for my camber from the last alignment to jump from -0.8 degrees before to -1.0 degrees after he aligned my toe (0.45 to 0.05 was the toe adjustment)??? I sort of doubt the quality of the sensors they have at the shop... my caster was 3.2/2.9 initial but yet 4.0/3.8 final after they aligned my toe. Sorta seems odd that it would change like that.

Either way, I dont understand how 2 washers corrected 0.6 degrees on one side and 3 washers also corrected 0.6 degrees on the passenger side .

I'm guessing either each 1.75mm washer corrects for either exactly -0.2 degrees of camber and my final camber was in fact -0.8 instead of -1.0 from the last alignment (so 0.4/0.6 corrected).
Or maybe each corrects -0.25 to -0.275 degrees and the sensor rounded my camber up/down for this recent alignment.

Just food for thought on planning out how many washers to use. I plan to look for 55-60mm flange bolts to fix the passenger side a bit more.
