Many people with E46's run ST40 on all four corners as it offers many benefits. My opinion is to go with the ST40.
1) Ability to rotate friction rings and pads
2) ST40 is a little lighter
3) ST40 pads are a little cheaper
4) 4 piston is the max you're able to run within BMW CCA Prepared Class
5) Cheaper initial cost
Z4M_GT3 just installed this exact setup and might be able to provide better details than me.  |
I think you mentioned everything on point as I would haha. As far as braking feel, ST40 all around feels PERFECT. I have driven MANY cars with multiple kinds of setups, I must say 4pot 355 all around was my favorite. Stoptech or PFC are the winners for me. I got the ST40 Trophy kit (new one's fixed the pad knock back issue fot track use, so its perfect) and I am VERY pleased with them. =)
But as far as fitment with stock wheels I have nooo clue.
