STOPTECH ST60 & ST40 Parts Info

[0-60motorsports]

Zeckhausen is a phenomenal source regarding stoptech, especially since they've become less than stellar to deal with directly and parts supply has become extremely difficult.

For replacement seals and boots, i'd recommend looking at Girodisc, they also supply replacement rings for stoptech kits which are fantastic.

Yeah it is an awesome source for sure. Thanks to them we some good info, Girodisc are definitely what I am going for but First need to sort out the calipers and pads too.

Ive got dust boots should you need them. I haven't rebuilt stoptech calipers in a long time but they use the brembo dust boots..

In the off-chance that your boots are still intact, it will have the piston size on them:

Oh perfect! Yea they are / should be intact. Thanks.

This is how I measured:

Good looking out, I would have just measured the tapered portion.

I'll figure out a way to measure them if no one here has the info as I can't disassemble them and wait two weeks for parts to arrive and then another week to get the PC done etc.

Email David Zeckhausen. I think its [email protected]. He might be able to ID the piston sizes without measuring them.

Weissgold is nice and would look subtle behind the LM's.

I've got a set of non trophy in the garage I should be able to measure the pistons for you tonight.

That color sounds good! I'll go check the samples one of these days and post up pics.

Thanks that would be great.

Thanks for that info. I am guessing i am going to have to remove the calipers and measure them as mine are the Non Trophy versions.

ST60 Front:
2x 36mm
2x 34mm
2x 28mm

ST40 Rear:

A front-only kit will have different piston sizes than above.

For example my old (Gen4 ST40) front only kit had:
