Guys,

Does anybody sell the spacer required to make these fit or have a diagram that I could use to get some made?

Thanks

 

Im interested to find out too. Much easier to find gt2/3 pccb than turbo pccb

 

The GT3 discs have too little offset for the TT. 61mm vs. 63mm for the Turbo.

A 2mm spacer between the hub face and the disc works to put Turbo discs on a GT2/3 but not the other way around.

 

You can use a 997tt 350mm rotor, and the GT3 caliper will bolt right up.

 

Sorry I am not quite with you on this. So you have to space out a turbo disc (between the hub and back of the hat) for it to fit a GT. Thus the only way of making a GT hat fit a turbo would be to try and machine a couple of mm off it?

 

One other question. On the Gen I rotors, can you just unbolt the GT hat and fit a turbo one?

 

While machining 2mm off the inside face of the GT disc hat would increase the offset to 63mm, it would no longer be structurally sound.

The only way to make it work is to use the Turbo hat provided you can find one.

 

So if I got hold of a full set (4) pccbs from a GT2/3, I could use just the rotors as spares for my turbo S' pccbs by disassembling them?

 

I think so. The rears bolt straight up but you would need to disassemble the fronts and bolt the rotor in to your turbo hat. I don't think there is much call for GT hats unfortunately.

 

Has anyone here taken the rotors off a pccb GT2/3 and reassembled them to their turbo pccb hats, to make up for the different offsets?

 

And does anybody know what tension the fittings should be done up at?

 

are the same pccb gt3 and gt2 996?
regards

 

Yes they are.
