Have the following StopTech brake caliper pistons(aluminum) for sale:

36mm bore x 32mm length (Qty 4)

34mm bore x 32mm length (Qty 4)

30mm bore x 32mm length (Qty 12)

They all have less than 300 miles on them(one track weekend). Perfect working condition. Perfect bore surface on all of them. They are all hard coated, with the coating in perfect condition.*I swapped them out for titanium just because I wanted to. Couple of pistons have small nicks where they make contact to the pads which is non-critical area, they got nicked during the extraction procedure even though I was being careful. In this video below shows the extraction and swap of these pistons that were used for only one track weekend.

These pistons came on GT3/RS Stoptech Trophy Sport brakes. From what I understand these pistons are also popular upgrade for OEM piston replacement on OEM calipers. Buyer is responsible for verifying piston fitment for their application. This link shows caliper rebuild info-*https://www.zeckhausen.com/catalog/i...Path=6446_6494

MSRP is $25 piston. Selling for $15 pistons. Or $200 for all.
