Hi, phoned up about these as but someone was coming to look at them and he would call me back if they did not take them. No call back so presumably gone. They had no nuts either, which I understand are tricky to get hold of. I'm not sure if running on a 165 tyre would ruin the handling a touch either?
I run Gordini wheels with 155's and the handling is unaffected.
Put 165's on and they may touch the wheel arches at the back.
Have a look at this.... http://www.renault4.co.uk/forum/showthread.php?t=2342.
I got wheel nuts from Renault turbo spares, no problem, second hand and cheap.
You can modify original wheel nuts, it's explained on this web site.
I think it's a Ø10mmx1mm pitch thread on the studs, and the countersink is 90° in the wheels. So making new shouldn't be too much of a problem either, if you know a good turner.
Don't use original wheel nuts on Gordini wheels, they don't fit and ruin the wheels!
Regards.
