15x7 wheels on a Fiat Spider

[Peter Cripps <cripps@domain.elided>]

OK, here's my  third message of the evening, just to liven things up and
stop James from going to sleep!

Anyone got any experience of using 15x7 wheels on a Fiat Spider. I have
done as much measuring as I can, and it looks OK -- the first thing to
interfere seems to be the roll bar. But advice from someone who's one it
would be nice?
