I bought these to use as spare wheels for my track car, but they have no use for me now. The whole setup has been mounted and road-force balanced, and spent about 40 highway miles on my car.

Asking $500 o.b.o. for the whole setup. Pickup in the East Bay or shipping in the CONUS at the buyer's expense welcome.

Tires: BFGoodrich g-Force Super Sport A/S, 185/60R14 (originally ~$475 before tax/shipping)
Wheels: Kosei K1-TS, 14x6 (originally ~$375 before tax/shipping)

These are among the grippiest UHP A/S tires available for the Miata, and offer performance similar to some quality summer tires (but certainly not EHP summers).

Fun fact: these are the tires that are used on the Formula Skip Barber cars, albeit shaved.

You can still see molding sprues in some of these pics!
