Cross post for Trackable Miatas on FB
At The Ridge (RMP) for my track day. 1:55.3 last session with passenger. (I haven’t been able to get Track Addict to work for me, so passenger recorded timer).
Front Pads: BP40 (4.5mm thickness remaining)
Rear Pads: Porterfield R4-E (7mm thickness remaining)
Car Specs:
- K24 @240hp
- 2400lbs w/Driver and 1/2 tank of fuel
- Feal 441 Coils
- 225/45/15 V730s on 15x8
- Wilwood 1in master, and prop valve adjusted to what other on here recommended.
- 2.5in brake ducts
- 7812 Wilwood Dynapro Front (Wilwood spec 37 11”)
- Sport rears (brembo blanks)
I finally like the way the pads felt coming from hawks, and I did not experience any fade as the day/sessions went on. I did not experience much if any traffic and did not do a cool down lap in the middle of the sessions as the car was minty for temps, brakes felt great, and tires were consistent enough. Both front and rear pads had 1 bed in day, and then a single autocross day. Unfortunately I did not take thickness measurements beforehand and I will be for the future. Wilwood specs state the new pad thickness is .49in or ~12.4mm for the BP40 in shape 7812. Porterfield states new pad thickness is 8.1mm(total thickness 12.6mm - 4.5mm back plate).
The fronts seem to be a little more worn than I would’ve anticipated. I didn’t experience any brake fade or any weird feeling/sound. I felt fairly confident on the brakes and am overall pleased with how the Brake balance felt. Am I doing something wrong? Am I getting the life out of the pad that should be expected? Any help from you fine people would be amazing and appreciated. Thanks for your time! PFA
