Just bought new rotors and pads less than 100 miles ago but have since decided to go Brembos on the front. With that I'm selling my calipers off my B7 S4.
They will come with the new pads that have less than 100 miles on them with receipts to show when they were bought and when they were put on the car (like 2 or 3 weeks ago).

Only issue is it'll be a week or so before my calipers get here so I am unable to pull them off right now but I live downtown Chicago and take the CTA everywhere so miles won't go up on the pads.

Whole set - calipers and new stoptech pads w/sensors $450 OBO
