I have a set and a half of factory C-5 Z-06 wheels. Four rear 18's with Hoosier A6 scrubs and two 17 fronts with A6 scrubs. I have another 7 unmounted Hoosier 18's. they were off my 91 corvette that my grandson Adam Shipley and I used for local autocross events. They have been stored in my basement and not frozen in outside storage. They come alive again when treated with Traction V. I also have a set of 17 in Zygen wheels with Toyo R-1s that we used on the Subie 02 WRX and even the 13 BRZ.
Adam is out of college and lives out of the area. I sold the 91 Corvette and my Subaru BRZ and may only compete occasionally in my 13 Corvette GS. I'm 75 now and just not into hauling extra tires etc to events. By the time I change a set of tires now, I need a nap, not doing a work shift on the off driving heat.
If anyone can use these give me a call
