Brake rotor wear vs pad

[madjak]

Based on some other discussion threads I thought I would start a new one to track various rotor and pad combinations. I know driving style, weight of car, tyres, usage and power all factor heavily but if we get enough data it might help make some useful comparisons.

Car: NA6 165whp
Usage: Track / Speed events / Autocrosses
Calipers: F: Stock NA6 R: Stock NA6 O: Wilwood proportioning valve 100% open
Rotors: F: DBA T2 Slotted R: Stock NA6
Pads: Ferodo DS3000
Life: 5 x track events, 8 x sprints, 6 x autocross
Comments: Great braking but destroyed both the pads and rotors in one year of motorsport. I suspect that the heat generated by high friction pads on the small NA6 rotors caused excessive wear of both the pad and rotor. The pads needed to be at temp for any decent braking which made autocross and sprints difficult for the first few braking applications.

Car: NA6 200whp
Usage: Track / Speed events / Autocrosses
Calipers: F: Wilwood Dynapro R: Stock NA6 O: Wilwood proportioning valve 80% open
Rotors: F: Wilwood 11.75" UL32 R: Wilwood 11.44"
Pads: Ferodo DS1.11
Life: 3 x track events, 6 x sprints, 2 x autocross (currently at less than 25% wear)
Comments: Excellent braking from cold to hot. I'm braking a the same points as the previous setup, however I'm at much higher speeds due to the hp upgrade. Wear rate of the rotors is minimal and pads seem to be lasting well. The pads had to be cut manually to fit both the front and rear which was fairly tedious and dirty work (approx 2 hours). These pads offer a linear friction coeff from cold to hot so are much more suited to mixed events. I expect 2 years before replacement.

Car: NB8B Stock motor so maybe 135whp?
Usage: Track Day / Sprints
Calipers: F: Stock NB8B (sports brakes in the US) R: Stock NB8B (sports brakes in the US)
Rotors: F: Stock NB8B R: Stock NB8B
Pads: Hawk Blue
Life: 12 months, approx 12 track days, rotors last at least 2 sets of pads.
TYRES: Nitto NT-01
Comments: Wear is good, stops well, rarely fades except after repeated high speed to low speed stops (i.e. end of Calder park straight). Pads are a bad choice for a daily or road car as they'd chew rotors and wont stop well cold.
