I was thinking of doing a R33 GTST caliper upgrade for my S13 but i was not sure what Brake Master Cylinder and What SS Brake Line to use?

I heard you could use Z32 TT rotors but i wasnt sure of the BMC and SS BL

What Size Brake line did the R33 GTST use?

i'm using the z32 master cylinder and i'm also running z32 SS lines front and rear with my ECR33 front and rear calipers w/o any problems

you really shouldn't run z32TT rotors when using ECR33 calipers b/c the ECR33 front rotors are .5" larger in diameter, plus the ECR33 front calipers use 32mm pistons rather than the 30mm or 26mm pistons from the z32

btw, everything just bolted right up too. we're working on a custom e-brake setup utilizing the stock s13 rear calipers....i'll be sure to post up pics when we're done
