Brand new Stoptech Rear Race Hats for 345x28 STR BBK with an exclusive high-temp natural hard anodized finish(Not the standard black that might change color when exposed to high temps). One pair.
These were never installed, but are spares for our Time Attack 335i bak in 2008-2010.
Only the rears are still available.
Retail was $475 each but likely more now.
