Your WW brake system did not almost kill you, using the wrong pads that did so, and not checking your pads
After ever run you should go over the car, especially the first time out with a mod, tire temps, wear patterns, air pressures, nuts and bolts, shake the wheels to see if the bearings, tie rods, etc are tight, torque the lug nuts at least once if not after the second session as well.
I found out before running the BP20 pads they are made for hot rod cruisers and then spent $400 on Carbotechs overnight shipped to me and I still ate up most of a $200+ set of front pads in two days.
I would of run much cheaper WW pads, real track pads, but could not get them in time, I have a couple of more sessions left on the front Carbotech and plenty on the rear(custom WW front and rear BBKs) so will match the right WW with the rear CT pads until they are gone then just use WW after that as they make many versions and all are less than other brands that I have found so far.
If a vendor told you or advertised the BBK as a track ready setup with the parts shipped including pads then that helps a bit but still your responsibility to check, everything. Perhaps if so they would help you get your brakes back in shape, never hurts to ask and if they are partially at fault, they should.

NOTE:
GET GT ROTORS with your kit if you are going to track the car, they will last far longer as have better venting, better metal, more precisely machined and have more weight so deal with heat better, pulling heat out of the pads and thus calipers, fluid......
If a real track junkie add brake cooling, fog lights or if a TR splitter, I have both worked out if interested.
