ST205 Front Brakes

Suspension and other discussion

swap 185 brake for 205 is not only for the caliper
bigger disc are usefull too

why use a braket when drill a bigger hole in the caliper make them fit ?

for the MC, 185 and 205 are both 15/16", same lenght, same mount, no reason to change
but 185 ABS don't really like the new brake setting (if you have one, try to "unfuse" it)

that's for sure! :D
btw, correct me if I'm wrong, but I don't think that ST205 front calipers (and brake pads) can be used with ST185 front brake discs (aren't they too small?)

I don't think 185 disc goes with 205 caliper because off the offset disc itself

I have the 205 complete brake kit to install on my 185 (no picture yet but will give solidworks part plan when complete)

rear are bolt on, every knows

front disc need approx 4.8mm spacerbetween disc and hub to clear the hub, we need a 4/10 mm metal rubber to modify the bore of the hub to center correctly disc and wheel

All that is done for me, i will work on the braket to fit the 205 disc with 4.8mm spacer inside and the 315x28mm disc

We are use to see S14 with 300ZX TT disc here in Europe, i am sure i could the same with 205 brake on 185

i will finish my rear drive train the 1st of may (205 LSD, polybush superflex from FENSPORT, D2, crossmember and diff bush kit from Mario, ARB from WHITELINE, ARB link from TWOSRUS, fuel cell from SUMMIT, new full avia brake and fuel hose) then i will start the front drive train and share you some informations

To mount the calipers on the 185, according to my measurements, using the full size ST205 318x32mm disc, you will need to space the rotor outwards 4mm to clear the ball joint, you will need to space the caliper 1mm outwards to center the caliper on the disc, and you will need to move the mounting points 18mm outwards to sit the caliper where it needs to be for the st205 disc.

This is one way to do it. You will need a bracket if you want to use the full 315[mm] of the ST205 disc.

I have my front set painted and waiting to go on. Need some new cilinders and rubbers too.

i finally go that way but with ST205 full size rotors, 5mm rotor to hub spacer

my prototype will be ready next wednesday, if it's work i will give you the draw of the braket and the way to mod the caliper

i do that way only because i need the car running the 09/15 to practice the 09/30, but with more time, i would look for some 330x30 rotors, with that size we have more facilities to draw a braket without mod the caliper and 330x30 or 32 are hummm : 8)

i have easy to find another front set of 205 caliper to do the next step (330x30/32) but you guy are so far, sell my full front mod would be too much in shipping to US countries :oops:
