do you specifically want or need frp brakes? you can get better cheaper calipers brand new! wilwood 6 pots for example, 500 quid at rallydesign, lighter will give better braking results more pistons etc give a better feel, also wont need so much maintenance and wont corrode and become useless
i can understand frp owners wanting the alcons to keep the car original etc, but anyone else buying them are paying a massive frp tax on them which you could use to get better elsewhere
