I want to thank Jaime, Gary and the whole crew at Brembo for all of their help and support with this project. This is the first kit in N/A to be installed and the first from Brembo made specifically for our M3.
IMPRESSIONS:
My initial impressions are based on just less than 1000 miles, mixing highway and city driving, and after a proper bedding-in under the supervision of Brembo's product specialist. I am planning on making the trip up at month end to Willow Springs for the upcoming BMWCCA event, so we will have some more impressions, particularly regarding fade, soon.
The car does
feel quicker overall and I suspect that may be due to the reduction in weight with the swap. I just picked up the OEM brake assembly from Brembo an hour ago. I am fixing to get them weighed here this afternoon to compare to the BBK. I will post the results on
lucid's weight reduction thread in the General Forum.
Stopping is now entirely different with the Brembos. It is not as sensitive on initial input with the pedal as with the OEM. There now seems to be depth to the braking action which is nicer, giving you more feel. I have had no fade issues as of yet, but haven't taken it to the track either. Stopping power seems limitless. June 1st's upcoming BMWCCA event will bring more insight as I plan on putting them to the test then.
Brembo has calculated the heat loads generated on the stock brake system and determined that the 380 x 34 on the front and 380 x 28 on the rear best handle the demands placed on the M3. These, along with stainless steel lines make up the specific kit Brembo has introduced for the car. The kit will fit with the OEM 19" wheels with 3mm clearance (min. req'd) between the closest point of conflict (the wheel balance weight) on the wheel and the caliper. I chose the drilled over the slotted since the car will only be tracked a few times a year initially. As an option, you can select the slotted rotors which provide a more even heat/cooling cycle which track users will prefer. The drilled rotors will tend to cool faster and are generally more suited for street use.
...more to come.
