Where to find stainless caliper pistons?

[packratbimmer]

RUST arggggg! I am tired of fried rotors due to seized steel caliper pistons. Where might we buy stainless E30 caliper pistons? Thanks!!!

I would be interested to hear if you find some.
Failing that, grease under the piston boot when you do any sort of service around the wheels and it'll probably stop them from corroding and seizing.

I'll let you know if I find anything. I have been using Ate grease as you describe. The road chemicals are brutal here. They do not sand the roads before storms - it is straight to the salt. Brand new rotors after a winter are compromised if not ruined. Not a big deal, except nobody resurfaces rotors now. I think I am going to implement winter dedicated brakes on both cars that are driven in winter with a full cleaning each spring after the snow melts.

I checked their website and saw nothing in stainless. Should I call them?
