STOPTECH ST60 & ST40 Parts Info

[0-60motorsports]

This is how I measured:

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.

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 ST40 Rear “Trophy” kit piston sizes:

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

ST40 Rear:
4x 28mm

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

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

2x 44mm
2x 38mm

Hey All,

I am creating this thread for all of us who have STOPTECH brake systems and to have the info and suggestions from community members in one place.

I have the Black Stoptech ST60 355MM Front & ST40 355M Rear Big Brake Kit on my E46 M3 and have been having a tough time sourcing some parts and getting in touch directly with STOPTECH. I used to have a dealer account with them and all my POCs are gone and I cant log in and cant contact any one so here are the parts and info I am looking for without having to take my brakes apart:

Boots and Seals Kit:
Anyone know the Sizes for the pistons for ST60 and ST40 E46 M3 application specific, please post them up.
E46 M3 ST60 Piston Size for boot and seals kit
E46 M3 ST40 Piston Size for boot and seals kit

Brake Pads:
ST60 Street Pads recommendation and if they can support the wear sensor that'll be a plus

ST60 and ST40 Rotors:
As far as Rotors I have found two options and am leaning towards the Girodisc due to having direct contact with them and they being a breeze to deal with:

Another choice is Stoptech's Aero rotors

Zeckhausen has a great section for STOPTECH parts: https://www.zeckhausen.com/catalog/index.php?cPath=24&osCsid=df7jt8588q9nmv8cjhli1amk 67

Appreciate all the help guys as shop is full so If i have the above correct parts in hand in advance I can just take the car in and have everything removed and run the calipers over for powder coating.

Any suggestions on what Caliper color might be OE+ on a JB M3 Coupe with Silver BBS LMs?
