sw20 camber bolts

Steve, the stock camber bolts only have enough play to give you about 1/3 of a degree adjustment.
For more adjustment, I would advise you to only use the genuine Toyota camber bolts.
 
There are 3 different sizes as well as  stock, and have small raised dots on the head to indicate the sizes.
 
I got mine from Twos'rus but they are not that expensive from the local dealer.
