Scion/Toyota is an example of a manufacturer who prescribes them so they are allowed for the FRS crowd.

This was my point when I stated "not available".
The E36 bolts will fit but you can't use them legally for Street since they're not listed for the M.
It's just mind boggling that for Street class SCCA considers all Z4's from the 2.5 to the M equal, but doesn't allow the M in STR.

Even with the 255s you should be able to get to -2.0 degrees with the camber shims. You'll have to keep an eye and the spacing between the inner tire sidewall and the strut body. Worst case you use a 5mm spacer to give added clearance if needed. If you install camber plates it's moot because the whole steering knuckle and strut move as one so the spacing between the tire and strut remain constant.
