Big Brake kits do not really shorten stopping distances on the M3. What they are damn good at is dissipating heat. Larger Rotors and hardware allow them to become better heat sinks. So you can apply the brakes all day long at the track with no fade, or heat related issues. All for the entry price of Approx
The big plus with the Movit kit is being able to swap pads in seconds! So you can pull your street pads off and replace with PF90's or several other track pads of your choice.
Many folks are just running the fronts and love the setup. Unless your a real track junkie ie. 8+ days per year I would look into other options..Unless $'s are not an issue for yah.
One of those is to apply the same principle that the Big Brake kit does.....Keeping the rotors cooler.
A Brake cooling kit such as the Bimmerworld kit will deliver the same fade free, rotor & pad friendly results. I looked at getting the Movit kit but decided to try the Brake ducting first. If I could spend $300 bucks vs $3000 why not? It does'nt take a rocket scientist to do the math!
Several M3 owners have tested the BimmerWorld kit all with outstanding track results. A few have even measured rotor temps with one hose pulled off. Posted results show a 200+ Degree difference
with the cooling kit. This kit works!
You can run stock rotors, or Euro's with this cooling kit and your choice of street pads....Because the temps are reduced you will not tax the street pads as much allowing for safe fade free track time....As you progress and move into higher run groups you will need to think about a Track Pad, vs a street pad.
I currently run Euro Rotors with the BimmerWorld kit and Porterfield R4S pads for the street/auto X and Track. The pads have held up fine at the track with the cooling kit. I WOULD NOT RUN THESE PADS WITHOUT THE COOLING KIT! The additional heat generated quickly destroys the pads....
Good luck with your decision...
Feel free to drop me an EM for further info on the kit..
