Default Brembo 380 VS Brembo 355

Are the 380 mm just bling when it comes down to it ? Heavier wheel mass but has a better pad surface ? I have a boosted E46 M3 do a couple (2) driving schools a year and do not use it as a DD and trying to figure out the best route .. Thanks in advance

You also need to remember that most 18'' wheels will not fit the 380mm rotors. You are pretty much gonna be stuck with 19''s.

Pretty much just bling (380 mm).

355's with 4-pot calipers give plenty of heat dissipation and stopping power, along with 18" wheel options. (or 19's if that's what you want).

Member docwyte ran a boosted E46 M3 with 355x32 ST-40's all around, and his reports indicate that he was quite satisfied with the braking results.

355's + good track pads and you'll be fine.

I hope so .. The 380's are pimp in so many ways .. also the drilled look vs slotted cant compare .. I will update in the next month or so .. Thanks everyone for your suggestions and time as I will have the 355 345 installed soon .. Now If I can just live with some 18's and 295's I will have one beast on my hands ..

355 work great. I was told 380 requires upgrading the master brake cylinder; I'm not sure if that is true or not.

+1.

Bigger heavier 380mm rotors + bigger heavier 19" wheels & tires = greater unsprung weight at all four corners.
