Hi,
I'd second the recommendation for the Superlite Wheels at the above link... They are a whole lot cheaper than Panasports and very hard to tell one from the other. I think the Superlite standard wheel is a little bit lighter than the street version of Panasport. And, Superlites are made in the UK, like your car, rather than Japan, like Panasports.
Superlites are offered in 13x6, 14x6 and 15x6 sizes for TR7. Personally, I've always thought TR7 would look better with larger diameter wheels than were originally fitted.
I plan to try a set of Superlites next time I need wheels.
Cheers!
