rumour has it, straight from the horses (Andy MIddlehhurst's) mouth, that the R33 GTR caliper is infact identical to that of the R34 GTR save the colour of paint!!!!
ps. I shall be offering the market a very nice set of R33 GTR calipers for sale, used by the legend himself ( Mr Middlehurst),
on his road car, but only when the commuting fiesta ! arrives, gasp ! (powerful). This should (good house purchasing process) be around late September.
