What's a ph2 cup?
Renault only I'd guess.
There were a couple on eBay last week. Have a look there.
172 cup as per avatar
hmmm.... I have just bought a 172 thats going to be a track car, I can't see me needing one of these.
Is it easy to take it off? If so I'll sell you the one off mine! PM me if interested.
