e46 brake conversion non m to m?

is it a direct replacement to install m3 pads rotors and calipers on my 330ci to save money with out having to buy big brake kit or is there additional parts or custom work involved

Carriers will have to be milled for the front. Rears will be more complicated. Search, there are threads on this.

i thought 330 and M share same brakes..

Uh no. Why would BMW upgrade the power on the M3 and leave the brakes the same as a 330.

i mean csl m3 brakes

you do realize the M3 and 330 both have 325mm front rotors, right? the 330 brakes are more than fine. you don't need to "upgrade"

i am running a t4 turbo on 13psi over 450 hp with other performance upgrades and a full suspension . that's why i am planing to doing this m3 csl brake upgrade with hawk pads and stop-tech cross drilled rotors . just wondering what is this swap going to run me in parts ?

seems like my best bet is to just stick with my 330ci setup and get brembo big brake system. looks like i wont save any money

thats what you should do

325x28 vs 325x25 .. more meat more heat

i would prefer the 380mm m3 brembo kit tho over the 330ci 355mm kit since i am rebuilding my lover engine components this summer to run more psi planing to have 600hp and the rebild my engine head at vac hoping to have over 700hp complete . thanks for all help

They're not. Rotors are about the same size (M3 rear rotors are a little bit bigger, but also thinner), but the hydraulics aren't really the same. IIRC the M3 calipers have bigger pistons, and the M3 has a bigger master cylinder too. This is probably mostly the pads, but the M3 brakes have noticeably more bite. And unlike the 330 brakes, they're not death traps in the rain.

How are 330 brakes death traps in the rain?
700hp hey.... What diff are you running?

Check a friend's website for machined carriers and Porsche big calipers.
Less expensive than others and excellent performance.

i went from a mt 330 diff 2.92 to 3.38 from a auto 330 diff and swaped the trans from 5 speed to a zhp 6 speed to bring the top speed back up . just need to make it a lsd becouse i dont get any traction during accel in first gear with one wheel spin

Every RWD 330 I've driven in heavy rain has unresponsive brakes for about a second after a few minutes of no braking activity. Didn't matter if the rotors and pads were brand new. Lines and fluid didn't do crap either. M3 never had the same problem.

Loads of 330 owners experience the same thing: http://forum.e46fanatics.com/showthr...t=68805&page=2

Can't say I've ever run into that problem with my 330i.
