997 Turbo Stock Brakes For E92 M3

[BURAKUSTA]

HELLO

Is is possible to fit 997 turbo brakes(red brembo ones) to e92 m3.I am asking this because brembo offers bbk for e92 m3 in 6 piston at the front and 4 piston at the rear.Maybe calipers are the same part number ?

Probably not.

yea prolly not... theres more then just bolting it up, you need custem fab'd brakets, new steel braided lines, bushings, shims, brake boosters... just a whole lotta headache...

Not to mention differences in brake caliper piston sizes, brake master/slave cylinder differences, F/R brake force distribution etc.

The cars also have different bolt patterns, so you can't simply slide on the rotor either.

Cutting brackets is not hard you can buy a prop valve and adjust bias. I'm sure you can find a rotor to fit just measure backspacing and what not. I own a shop I make stuff work like that all day don't listen to these people. If you never try it will never happen.

Your brake booster/master should be fine they just move fluid

It's not that simple on a car that can independently control the pressure going to each brake caliper.

No, they move different amounts of fluid based on the measurement of fluid displaced for pedal pushed and the size of the pistons it needs to displace. So you can end up with a very sensitive pedal or one that isn't responsive at all. The ABS system will be way out of whack as well.

There is always fluid in the caliper your not filling it every time it only has to move a small amount of fluid. If you are really concerned about it measure the fluid volume in each caliper. How do you think aftermarket brake companies make big brake kits? For the most part they sell the same caliper with different mounting hardware and lines. It's not rocket science it's a BMW guys.

They have the same caliper body but the pistons they put in the caliper are different sized matched to the car it is on.

Believe me, I know what I am talking about. I've ran BBK setups on all sorts of cars. Retrofitted 300ZX 4 piston brakes onto the 240SX. Ran Wilwood big brakes on a Honda Civic... it doesn't work. You need to change the master cylinder, slave cylinder to match the brakes you are using. Even then you end up with uneven F/R brake bias and a whacked out ABS system.

My 240SX with large front 300ZX brakes was crazily front brake biased. I would step on the pedal on track, the front brakes would lock up and the rear brakes would be barely applied at all. It was downright dangerous to drive. The front wheel would lock up and the rear end would step out every time you hit the brake.

What you are talking about would work on an old car before modern brake systems came about. But to put brakes from another car the correct way is to replace the entire brake system with the components from the other car.

Just because you didn't know how to set your system up doesn't mean it can't be done. I do stuff like this all the time it's not hard.

Do you know how to recalibrate and program ABS systems?

Try it, then. Put Porsche Turbo brakes on an E92 M3, make the "simple" changes you propose, and then take it to the track. Let us know how it works out when you enter the braking zone for turn one at 140mph.
