Thumbs up Brembo 380MM BBK vs Stock M Brake Comparison Photos

Below are some comparison photos between the Brembo GT Front and Rear 380MM BBK vs. the Stock M Calipers and Rotors. Enjoy

P.S. Sorry for the iphone pics! We'll have a quality photoshoot posted soon.

Can you show the inside of the rear Brembo rotor? Is the center aluminum? Just wondering how the e-brake works on the Brembo if the center is aluminum.

You can utilize the brake wear sensor on Brembo's? Do the pads have the insert slot to accomodate the sensor clip? Very nice!

Look at the last pic in the post below:

This is typical of all BBKs that retain the stock e9x M3 rear parking brake - the parking brake shoe is preloaded against an anodized/chemical-coated Alum drum. I'm running the Performance Friction BBK and I find the parking brake holding power to be very similar to the stock setup.

Thanks for the info and pics. I'm just surprised it's an aluminum hat.

you can advise your tech that cutting the entire rear shield is not necessary, also the removal of the front shield is not required as well.

Explain what? You may want to retain those shields for the street. If you drive through standing water, your next stop may be a little interesting. Unless the E9X M3 has the auto brake drying feature then those shields are mostly to just keep debris out.

I would cut those shields off if you plan to do a lot of track time.

I believe they are about $350 each for the drilled ones from Zeckhausen. I would imagine prices are similar elsewhere.

Just a trim is all that's needed, not full removal.

Was there any reason you went with Brembo over others (e.g. Stoptech?)

Don't flame me here... Maybe this is a stupid question when involving the letters
B,M and W. But why in the hell are these BBK's so damn expensive? Over $7,000 for 4 rotors, calipers and pads?

No but seriously go track your car and almost get in a crash because your stock brakes completely fade on you.

The $7K is like insurance, peace of mind, etc. Priceless in my opinion.

Your stock brakes aren't going to fade on you so hard that you go off ... You'll feel it gradually start to fade and make adjustments. Any BBK is just to ensure you don't experience that fade as quickly, if at all.
From what I've heard these perform very well. I wonder if anyone has gone from this GT380 to the AP Racing kit and noticed a difference on the track?
