hi. looking to set up my old OEM 17" wheels for track-only duty. 7" front and 8.5" rear. questions ...

what is the widest folks are comfortably running on these things at the track? on my 8.5"/10" 18" wheels i am currently on 245/275 and was just as happy previously on 235/265. i think 235/265 would be a stretch (get it? get it?) on a 7"/8.5", but the internet tells me it has been done. otherwise 225/255 seems pretty standard.

tires? had my heart set on hoosier r7's, but the sizes are just not there. i need DOT to stay in my class, but want something more aggressive than an nt01. bf goodrich r1? toyo rr?

thanks for any advice.
