STOPTECH ST60 & ST40 Parts Info

Thanks to my good friend Mr. David Zeckhausen:




Kind of expensive though at $280 for a set without shipping for all 4 calipers for the caliper dust boots and pressure seals.

Yep. Agreed, I priced them out and was surprised at the cost. I've run my E36 M3 with Wilwoods for years without dust seals or issues

Interesting my front caliper piston sizes dont match any of those.

There were several variants of this kit through the years. Personally I wouldn't rely on what other people's piston sizes are without measuring them myself. These parts are not easy to return.

OK perfect I'll get on trying to source these from the person in this thread. I still might check mine in order for us to make sure. Thanks.

Jae may be able to confirm, but I'm not sure if he has 60/40 or 40 f&r

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

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

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!

Mike
