Got my Arachnids and never had them fitted as I was waiting to need new tires on the MS.
Now I'm picking up my M3 and will be handing back the MS, so don't have any use for the 21" Wheels.
Brand new Michelin super-sport rubber is like $2,750 - so I'm asking $4k for the lot.
Pick up in Marin or can drop off in SF City/Palo Alto.
Also got a red radio flyer up for grabs if interested.
