I have one Calliper for sale. It’s brand new and comes drilled and tapped in the proper place, rather than feeding in through one of the bleed nipple holes as per standard.
I am pretty sure this was originally for the rear of a Motorsport Elise. The calliper is the same standard size as a regular calliper though, same size pistons. etc etc.
Can be used for either side, simply swap the bleed nipples and bridge pipe over.
