Stock Z4M brakes - best pad for autocross and HPDE?

[TexasZed4MC]

I use Carbotech 10 and 12, but the developer of CarboTech sold out and started another company...just can't remember the name.

Are the Brake pads on the E85/E86 the same as the E46 competition Package?

Stoptechs IMO are the best compromise pad for street and track.
I ran them extensively before I got the BBK.
I tried others and came back to Stoptechs.

With the BBK I use Stoptech for street and Hawk for track.

They are a great pad.

I have had friends run Stoptech street pads at the track and they do not do well at all. They are driving different cars of course, but I don't think I'd ever use Stoptech streets for the track especially after experiencing decent race pads like the Pagid RS29 that I use.

I should add, since you're installing new pads I would replace rotors near min. For reference, I got 13 track days out of my last set of front rotors and pads. Rear pads were also shot but rear rotors are only about at half.

Holy crap!!!!

Only 13 days out of a set of new front rotors???

Including tires (about 3-4 track days), this is gonna get expensive…
