981 track pads
Discussion
What's the go to brake pad when tracking a 981 and how many miles do they need before they bed in?
My plan is to bed them in and refit them the evening before a track session. On other cars I would use something like Ferodo ds2500 on standard discs.
While we are on the subject, is the standard cars brake fluid up to track work? Whatever it is OPC uses when they do the brake fluid.
Just to add, I've never tracked a 981 so I have written all of this on the assumption it will be a bit pants.

there are loads, most track pads hate pad transfer so swapping pads is a no go for track pads. heat is the killer and a Pagid pad will not really work on a contaminated disk. Standard fluid is not upto it either. nor is cooling.My plan is to bed them in and refit them the evening before a track session.

A 981 will apply rear brakes for you also so they will over heat and fail :-(
but if you are on stock geo then you will have tyre issue more than brakes. ie you will melt them and bend the tread over esp if P-zero lol
net result is a very bumpy ride if you do this.
best pads are Endless, have a sit down when you see the price, RS29 are well know, again expensive.
but imo you will only do 3 laps if can pedal a car ok on oem tyres/geo , so brakes are nothing to worry about lol although you still may over heat the rears !!!

Will rears overheat in all 981s or just those fitted with PTV?A 981 will apply rear brakes for you also so they will over heat and fail :-(

I used RS29's on my CGTS. Weren't cheap but lasted at least half a dozen track days. In contrast, on OEM pads, I got through an entirely fresh set in 3/4 of a day at DN14 at the Ring last year. The rear's were down to the metal backing and I destroyed the discs completely.
RS29's squealed sometimes quite annoyingly in traffic, but temp wise, I never felt them overheating. I used Castrol Racing SRF fluid. Supposedly my mechanic says all DOT 4 fluid is the same, but for whatever reason, I felt the SRF gave me a much firmer pedal feel and consistency lap after lap. For the sake of £40 and half an hours labour it wasn't a big deal to give it a go.
Have fun, they are lovely cars to track.

Wouldn't use ds2500s on my wheelbarrow, rs29 are great track pad, not the best road pad squeal etc, a good all rounder is rs 4-2 obviously a bit of a compromise however.
Brakes fluid, srf great, ate 200 almost as good, (the old racing blue) but far cheaper. Halfords racing stuff is good too.

Just remember that any track pad will be very noisy on the street, especially coming to a stop and start / stop traffic. I know a lot of people asking for the best pad and then almost immediately switching back because of noise levels. Imagine a garbage truck or bus coming to a stop. That will be you in your car if you go for the R29s.

After a while, I found the RS29s quieten down a bit TBF. It's probably a little heat/weather dependent too, but even at their worst, it's only the sort of 20 - 0 mph, or possibly even 10 - 0 mph zone where they make noise. There's a little bit of shuffle/shunt from pads in stop-start traffic sort of scenarios too, but on the positive side, they really improve pedal feel IMHO.I agree, if you track the car the benefits of the R29s or similar clearly outweighs the negatives, however if you do the occasional trackday and do a lot of urban driving it will drive you mad. For me the noise came and went with wear and as you say dependant on weather and other factors. But they were never really quiet. Still, a lot better than the PFCs!
