Ok I'm looking at maybe putting a 17x7.5 w/ +42mm offset on my 91 si.

Now before anyone flames its my STS autocross car, and I'm looking at the Falken FK-451 (if the RT-615 isnt as good). The 451 offers a 225/35/17 tire that has the same roleout as the RT-215 Azenis in a 205/50/15, BUT its an inch wider....

So my question is would a 17x7.5 inch wheel fit with a +42mm offset...

Thanx
