There's some jr11 alloys on ebay, which look similar to pro race 1.2s. They can't be that much heavier, can they?!

Yep, I have 2 sets of these on a Ginetta G20. 7x15 and 8x15. They are lighter than the pro race 1.2s that I also have, but I doubt they are as strong.

That's interesting thanks. I was thinking that a light 7 could get away with a weaker wheel, especially if you have a driver who can avoid kerbs!
