STOPTECH ST60 & ST40 Parts Info

[fattycharged]

Thanks for providing the sizes. Are these for the trophy or the normal kit? ST60/ST40?

I believe the Trophy kit sizes were provided earlier by someone else. These are painted neon green, I thought the Trophy was anodized

Ok, so my findings on what I have from last night inner piston/outer boot measurements. My boots definitely do not have their measurements displayed and the part # on the boot did not lead to any results via leGoogle. Front boots are trash, Rear boots still good, not super surprising, but I need to do a full teardown and repaint/powder as well.

Rotors are 355mm F&R

F - 34 34 30
R- 28 28

Ah, that's a bummer. Those boots were the factory originals, and I got the kit about 3 or 4 years ago.

This setup was a takeoff from a recently acquired "racecar" I picked up off a shop last fall on my way back from CO. Assuming they replaced them with something they could more readily get parts for from multiple outlets. I likely won't even run them, more likely to just keep the DB9 kit and even run it with a 325mm rotor

Mike,

Will have to contact you once i know the sizes for the boots needed for both ST60and ST40 E46 M3 applications. Thank you.

If the community figures out the application sizes, I can request Frenkit to manufacture those specific kits if they are a unique combo!

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 david@zeckhausen.com. He might be able to ID the piston sizes without measuring them.
