Help!! I need e92M3 caliper rebuild kit!

attila · 10-13-2010, 08:32 AM

During my last track session I managed to melt the seals and dust boot around the front cylinders. (I melted off all wheel weights too, so my track session was over quickly)
I already ordered some part - PFC stage 1 kit - to replace/upgrade parts of the front brakes but I could not find a caliper rebuild kit for the e9x M3.
Any idea?
Thanks

Order the seals one by one from your favorite local dealer. Some of them are "kitted" up in sets. Have a look here.

Did you take the pistons out to determine that you melted your inner seals or are you referring to just the dust boot? Dust boots are overrated so if it's just those, than I wouldn't be to worried unless your car will see snow and road salt.

I've incinerated many a dust boot in my day (not in the M3) but never been able to melt an inner seal. In fact two years into my stoptech ownership, I purchased a rebuild kit but found that my inner seals looked brand new when I took everything apart - even though the dust boots were totally gone and the black caliper paint was a nice shade of grey.

I am running titanium backing plates in my stock M3 calipers which helps a little, but I am still cooking the dust boots a bit.

No I have not yet taken apart the caliper. But I will just in case. The dustboots are melted on a few spots, so just in case i will remove the piston but I would like to have the rebuild kit before I do it. I could order it from the dealer for $60!!!! amazing.
Already ordered the PFC stage 1 kit ($1260) maybe I should have ordered a BBK kit for the front.
My main problem though is the wheel balance weight comming off all the time. I am about to buy a wheel balancer for $1050 since I am spending $40 bugs on balancing the fronts after every second HPDE session. I tried crazy glue and some 5 minute epoxy. Helped some but eventually came off anyway.
Need cooling ducts or just retire the M3 from track duties and concentrate on my new MX-5 - much much cheaper.

Aluminum tape from home depot will fix your wheel weight problem. Most good race oriented tire installers cover the weights with tape.
I'd almost guarantee that your inner seals are fine. Keep us posted.
