Question is------Currently running for street and track, stock Fergat wheels, with 155x15 AVON CRZZ...looking at 175/70R15's from Maxsport (UK supplier) to replace my Avon's. Can I expect them to fit without body and wheel arch, interference in high performance driving situations (posted for Rod Mossop-UK)

I think 175 is a tiny bit wide for the stock wheels, but it shouldn't be excessive. You're 20mm wider than stock, which means the sidewalls will be flexed outward a bit. Realistically it probably won't matter much. On a stock car I wouldn't expect fender contact, but is this car lowered? Firmer springs and sway bars will affect that likelihood too.
