Stoptech ST40 piston sizing.

Was just wondering if anyone here with the Stoptech 332x32mm BBK, with an '03 non brembo, could tell me what size the pistons on their ST40's are?

Search has failed me.

Thanks.

Piston sizes are proprietary from StopTech, at least they used to be. I did measure them one time, but forget what they were.

I figured as much due to the lack of said info out there.

Thanks anyway.
