Many of you know that my ///M covered a large number of track miles each year in the UK and that I’ve progressively modified it over the last ten years to sharpen its track behaviour. With the relatively cooler ambient temperatures of the UK, I found that OEM discs and callipers were more than able to stand up to my rather aggressive late braking, at least once I’d fitted front brake cooling ducts, solid bushings, racing fluid and EBC Bluestuff pads. Whilst I didn’t experience any fade or other loss of braking ability with that set up, I did find that pedal feel became inconsistent as the brakes became very hot.
With that in mind and knowing that the temperatures on track here in Aus are much higher, I fitted an AP BBK front and rear immediately before shipping my car to Sydney. Since it landed, I’ve done three track days and found the APs to be fantastic. Stopping ability and pedal feel remain absolutely consistent long after I’ve started to lose concentration and no matter how much abuse I throw at the brakes (such as chasing a well-driven 991.2 GT3 RS and a less well-driven SLS Black at Wakefield Park - I lost to the former but passed the later after half a dozen laps).
However, the Bluestuff pads can get a little smokey and look like they have overheated after I’ve been pushing really hard. I suspect that they’re the weak link in the chain now, so I’m looking for advice from those of you who run a BBK front and rear on track, especially if you have APs.
For example, I think I recall someone describing an undesirable rearward shift in brake bias when using ultra aggressive pads at the rear as well as the front, but I can’t find that thread now. I don’t really mind how noisy the brakes are on the road, how ineffective the pads are from cold or how much dust they produce, I just want to know that I’m not going to hit the back of an ultra rare million dollar supercar when my brakes fail!
The disc bell started life painted black, as did the calliper - these brakes get seriously hot!
