I was at the Road America vintage races last weekend and saw a pair of cookie cutters on an early short wheel base Porsche 911. The offset allowed 225/50/15 Hoosiers to fit properly under the rear fenders. I would like to know what Porsche these came from so I can track down a pair of them. The offset must be around the same as the 911R Fuchs which are 49mm. Normal 944 15X7" ATS cookie cutters I believe are 23mm. Any information will be very helpful and appreciated.
