We found a reliable source for scrubbed porsche cup rear tires for $10 each! They are 27/68/18 and they are very fresh! We are going to run them on 996 turbo rear wheels 18x11 rear and 18x10 front (the 10” came from an early 996). We picked up two complete sets of 4 OEM wheels on ebay for $700 and we can sell the 4 18x8 fronts to recoup a bit into the budget. I’m really trying to convince my dad that it will be worth the tow out to GRM land from Uah for the 2010 challenge!
