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.

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!

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
