SOLD!!!!!!
StopTech E36 M3 + Z3M Coupe/Roadster front BBK. This is the ST40 (4-piston) setup with 332mm rotors. Calipers are gloss black. Braking with these will peel your contacts from your eyes. Don't let people tempt you into 355mm setups - 332 will handle everything you throw at them.

These can fit under factory Style 40 (Roadstar) wheels, but require ~18mm spacer for lateral clearance, and you MUST NOT have wheel weights within the narrowest part of the wheels' barrels (radial clearance).

Kit is lightly used and nearly-new. Only about 1000 - 2000 miles (zero track time) on them. Includes everything from the factory kit:Two black ST40 calipers (including the caliper bridges and four bridge retaining bolts with washers).
Two slotted two piece rotors/hats (332mm diameter).
Two mounting adapter brackets (that connect to the the factory hub/spindle assembly where the original caliper carriers mount) and four jet nuts + washers.
One complete set of ST front brake lines (banjo fittings) with two banjo bolts and six crush washers (two per banjo fitting, one at hard/flexible line connection)- washers are used, so you'll have to source new ones.
One complete set (four pads) of StopTech Sport brake pads (used).

Recently did a deep clean, polish, and ceramic coat on the calipers and rotor hats (not quite back to 'as-new,' but close). There is still some residual rust on the brake rotors. This is normal oxidation of the ferrous material in the rotors and pads.

In addition to the lightly-used StopTech sport brake pads, I'm including the currently-bedded-in pads, Porterfield R4-S, which are sooooo much better than the ST sport compound.

$1700 + shipping.
