Reply to "Question for those who are familiar with the European GTS"

1. My car has 15x8 rims .. I dont see any indication of long studs to accept spacers ... also less factory GTS Flairs ... my car being a later version in 1979 ... they didn't build my car with handling in mind .. it was more cost effective less spacers and flairs.
2. Tire size in the front is 225/50 with no rubbing issues ..even in hard cornering.
3. I think your right and when they moved them outboard that would explain the GTS Flairs.
4. I see the diagram ... i think the tell tail would be longer studs in the front.
5. The rear of my car has 305 /50 which also fit very nice ... i never looked or compared it but at times i thought the car had a wider look at the 1/4 panels

Heres a good picture in a hard corner ...
