Help A Twat Understand R34 Gt Brake Options.

[GTSBoy]

Should go on. The only question is whether the GT front brakes take a 14mm bolt (like those GT-T brakes you have there) or a 12mm bolt like all the other brakes that came before.

If your original brakes are 12mm, then your options are;

• Drill the bolt holes on the uprights to take the 14mm bolts (easy enough, done with care, but not easily reversible).
• IF GT calipers have the same style of knurled inserts with the female thread in them that the GT-T calipers have, then knock them out of each set of calipers and swap the 12mm threaded ones into the GT-T calipers. BUT.....I wouldn't expect this to be a thing. It would be a thing is you were dealing with some other set of Sumitomo Skyline 4 pots. I know, because I've done it. But the nasty calipers on the GT are probably provided with threads in a different manner.

Aren't all R34 14mm bolts?

Yeah, they might be. But these NA things fall into the region below my ability to retain information.

I'm sure the info is in here somewhere, but I don't recall R34 N/A people complaining about 12/14mm bolt differences.
