Used turbo twist style wheels with excellent blue powder coating. These came on my 968 when I bought it just last year, but I switched to stock Cup-2 style wheels instead. No dents or dings on the outside powder coating; just a couple rock chips on the insides where you won't see. Tires are well worn, but tread is even.
Front: 7.5Jx18 ET50, part # 993.362.134.06. With 235/40 ZR 18 accelera tires, some tread left.
Rear: 10Jx18 ET65, part # 993.362.140.04. With 285/30 ZR 18 Sumitomo HTR tires, not much tread left.
I believe these offsets are stock for a 993, but should work on a variety of Porsches.
