Choosing brake pads for Brembo GT Big Brake Kit

I didn't experience that. I wouldn't call the pedal firm but it's not a high temp pad either. If you want the bite and feel there's really no other choice than a high temp pad. You're asking for attributes that are contradicting each other and the tech hasn't caught up. A high temp pad is what gives you the bite and feel because, in it's operating temp range, it sticks and grabs the rotor which gives the bite. This same trait is what causes noise and high wear during street driving - the pads are extremely abrasive below their temp range.

The closest you'll get are the brake pads on the G series M cars - those are pretty damned good in both environments. Not sure if they come in the pad shape you need.

Yeah, I am coming to realize that is the case and possibly just go with a good street pad.

It's been years now since I had the Brembo GT kit, but I'm 95% sure it was the FM1000s that were my favorite ever street pad.

A track pad it is not.

That said, if you try to get the same pad for both, it WILL be bad for both. There's no street pad that's good on track, there's no track pad that's good on street, and any pad that works will on the track will destroy the finish on your street wheels if you leave the dust on them.

Half the reason to get a BBK is that it reduces pad swap time by 75%, when you go to the track. Swap pads when you swap tires, be happy, don't make the car bad at everything all the time.

Only downside to the Ferodo’s is the cost. They are close to $700 for all 4 corners.

I am really considering the Carbotech 1521 pads. I hear good reviews from other m-owners. I haven’t found anyone with an e46 m3 that runs them.
