We're both pretty sure the E36 M3 brakes will bolt up in front, and probably the rear calipers, but we're doubtful about rear rotors. Anyone BTDT? Thanks!

Bzzzzzt. Sorry, but unfortunately non-M e36 variants won't accept the calipers and pad carriers (brackets) from the e36 M cars due to different mounting on the knuckle of the pad carrier. The hot ticket for non-M e36 front brakes is e46 330i brakes as they will bolt on (still need the pad carriers, calipers, pads and rotors) and are even larger in diameter than the e36 M parts. You might also consider a master cylinder upgrade too as you're messing with a well designed SYSTEM of individual components. For the rear there are very few options. Rotors are no problem but again, M coupe/roadster calipers and pad carriers won't bolt onto the trailing arms because the mounting ears are different. Not to mention possible parking brake fitment issues. However, if you can find complete rear trailing arms, you might have a winner (caution, may require half-shaft mods in one form or another due to the rear hub/wheel bearing being larger on M cars). As a bonus the rear trailing arms of M coupe/roadster are gusseted and therefore stronger.

The first being a twin master with balance bar for tuning. :) If you're using only front brakes from the M car, then the answer is a bit less straight forward. Many folks use the M3 master, but this is clearly not ideal. At this point I'll give a shamless plug to a book written by a friend of mine. I bought one and it is a great read if you're thinking about brake upgrades. A pic of my M3 even made it into the book. :) He's done a bunch of consulting work for StopTech over the last decade or so and is an accomplished technical writer and SAE vehicle dynamics instructor by night and a brake systems engineer by day.

The 330i brakes are surprisingly heavier even than E36 M3 brakes, adding 10lbs. For the system-oriented, it definitely does not make sense. Ideally, the MZ3 rear arms/brakes with M3 front hub/spindle/brakes... which then lets you explore all the nice genuine "big brake" upgrades available for the M3. Short of going that far, freshening OE components and upgrading where possible yields impressive gains; fresh rotors, a good performance pad like the Hawk Performance Ceramic, fresh fluid, and stainless steel lines. - Rob ----- Original Message ----- From: "Chet Dawes" <[EMAIL PROTECTED]> Subject: Re: [UUC] Brake upgrades for 323ti > The hot ticket for non-M e36 front brakes is e46 330i brakes as they will bolt on (still need the pad carriers, calipers, pads and rotors) and are even larger in diameter than the e36 M parts.

So 330 brakes add 17lbs+ total. - Rob ----- Original Message ----- From: "Rob Levinson * UUC Motorwerks" <[EMAIL PROTECTED]> > The 330i brakes are surprisingly heavier even > than E36 M3 brakes, adding 10lbs. ------------------------------ End of [bmwuucdigest] digest(5 messages) **********
