Good point. Probably in the best interest to place a tire package that gives a similar F/R tire rev split to what GM developed the car around...

The wheels should fit without problems. Much of the suspension can easily transfer across trim levels as well
Interestingly enough, I have seen pictures of early SS 1LE struts/early MRC struts that have a different hub-to-strut flange than my SS 1LE and later SS 1LE's. The flange looked similar to the regular strut's flange instead of the sorta S-curved flange on my SS 1LE's strut flange. But, yeah, the regular strut flange does lend to more clearance for smaller wheels than 20's and reviewing photos, I can see the clearance on SS 1LE/ZL1 20's not being an issue between either.
