Hi there,

I am currently coverting my Datsun 240Z brakes to big Toyota Hi-lux calipers using Nissan 300zx non turbo 4 stud discs. I have already bought the spacer kit for the calipers, but does anybody know what size disc diameter disc you can use ?, as there are two sizesyou can buy which are 250mm and 274mm.

Does anybody know the right size ?

Thanks,

240Z Man

I read that the Z31 front rotors used for the swap in NA are " 11" " so that is 279.4mm
