Support Letter 27417 Except 6 Piston Front 4 Piston Rear Calipers
#29498 from Aaron Johnson · Not recommended · Minutes (2020-12 Fastrack)
Thank you for your letter. The CRB does not recommend expanding the number of pistons on alternate calipers to 6. The
responses to the distributed survey were overwhelmingly in favor of limiting caliper piston count to a max of 4. Market research
has also shown that quality 4-piston alternate calipers are quite plentiful, while on average the pricing of similar 6-piston calipers
increases.
