Selling a Front Stoptech ST40 BBK kit from a package deal I purchased. I do not need the front set, so it’s up for sale. Drilled Rotors are 355mm x 35mm and measure at 34.59mm and 34.54mm. Comes with Stoptech Sport Pads at 50% life and new Stoptech brake lines. *Sold As Is* Price is OBOand Buyer pays for shipping.

Bump, lets get these sold! :burnrubbe
Is this an E9X M3-specific ST40 kit and do you have the Stoptech part number on it? Are the bleeders free/unclogged? Hard to tell from the pics but are the boots/seals in good shape? Have the calipers ever been rebuilt? Any issues with any of it (stripped threads, leaks, etc.) or cracking in the rotors, especially around the holes? Thanks!
The bracket part number for the Front Stoptech kit E9x M3 is # 36-160-7419-05 The caliper part# 9128L and 9128R. Unknown if they have been rebuilt. The brake bleeders are unknown as I didn’t run the kit only purchased as a front and rear package deal. Spare bleeders can be found on zeckhausen. Boots and piston are in good shape and no issues I could see when I was cleaning them up. I left everything as I received it from the previous owner. Rotors have no cracking around holes and only light pitting on a small section on one rotor surface. Only other item I would note is some cracking of the exterior plastic on one of the braided lines.
