What brake fluid BMW puts in M3s?

I'm taking my 335is in for my 2 year maintenance and am thinking of asking the dealer to upgrade the brake fluid to a brand that has a higher boiling point.

Does BMW use the same brake fluid in the M3s as in the "lesser" three series?

My last service used part 81-22-0-142-156.

I think this is normal Ate DOT 4 fluid?

I used ATE Super Blue fluid on my last fluid change. It exceeds DOT 4 requirements, so the wet and dry boiling points should be plenty high for our purposes. I also like that you can get it in blue or amber color so you can see when you start bleeding the new fluid.

"officially" the blue isn't DOT approved, as it's not amber in color, but I do the same, rotate, the blue/amber each year.
