There is no way you can machine a reverse piston in a BMW to make room for more clutches.

Yes the piston can be machined down... you need a lathe and proper tooling to cut the aluminum piston down if needed.

question-350

Measure the thickness of one friction and one steel clutch, to give you your amount to machine off of the piston.

Or go to a trans shop that has been around for awhile and see if you can obtain a piston from them.

What does a BMW have to do with his question?

Machine the piston down the thickness of an additional steel and friction... also , additional .010 for clearance.

just the way I do it.
