7" rims or 8" rims?

Okay I will be getting some new wheels soon.

I was thinking 7x15" with ET20 would fit perfectly. I can then run 195/50/15's.

That's fine, but there aren't that many choices of wheels apart from say Rota Grid V's.

Most of other options seem to be 8" in width. Chay suggested I go for this, but an 8" with ET0 (which is what most seem to be) fit under stock arches?

Also I don't really want to over tyre the car, so am not that keen on going for more than 195's really and I don't think a 195 is going to fit well on an 8" rim, which means I'd need to go for a 7' really.

If anyone knows of other wheels that I can get in a 7" rim then I'd be interested to know about it.

I'm not a fan of the stretched tyre look really. I want my car to handle properly and it will be used on the road and trackdays.
