Does anyone know about the temperature ranges the pads and rotors will go through during hard driving on a twisty road or on a trackday (about 15-20min per session) I'm looking to buy pads for my roadster I'm looking to get Dixcel S type pads that are good for hard driving on twisty roads and light track use, they're built to be effective on temperatures from 0-700 degrees Celcius and I wonder if that's enough for my roadster , it will be used mostly on the touge and for hillclimb and autocross events, also in the future I'd like to track the car and go on trackdays.
I'm also leaving this link below to check out all the specs on Dixcel's official website
https://www.dixcel.co.jp/en/pad/pad_s.html
0-700 range is fine for a roadster on OE calipers and discs. Temps will be much lower on the road vs track, but a 700c rated pad is plenty, even for track work with sticky tyres.
I've been using the Dixcel ES pads on my Caldina for almost two years now and they have been spot on for fast road. Rated lower at 600 degrees so would hope the S version could cope with whatever a lighter chassis can throw at them.
Please report back as I'll be looking at brakes for my MR2 soonish too.
I would want to look for pads that have a good cold bite and within the temp range for the kind of driving you do so they dont overheat.
A lot of racing pads have poor cold bite and need to warm up before they start performing.
If you let the pads cool down between corners for road driving it places you on the other side of the compromise.

I'm a bit afraid of that too, it's the first time I'm getting performance pads

I once drove a Peugeot205, some many years ago, prepared and ready for the RAC Tour of Britain, that had
performance brakes. They simply do not work when cold!

I remember when I got to seat passenger in Loubet's Ford Puma WRC back in September we had to go a bit fast so the brakes would work on the public road, they were probably very worn too though since it was just after the finish of the Rally Acropolis 2022, rally cars even though they have to be driveable on the road even with modern tech are very hard to drive on road conditions

Sorry Officer, we were driving fast so the brakes would work!
The dixel pads listed are 0-700 so will be fine cold. Its when that first number is 100, or even 200 on some pads I've used. Now thats fun first thing on a cold morning when you forget ;D

hey I've been watching your videos on Youtube, thanks for commenting
I already tried the Dixcel Type Z and now the Project Mu HC+.
It's very similar, very very good brake pads !
Before, I had EBC Yellowstuff and, it's ok for road use, but for a track day, it's too limit.
After my Project Mu, I will probably try the Endless MX72+.
I had an interesting experience last year with brake pads that I use with my front Wildwood Powerlite calipers.
This is strictly for street driving so I decided to use the BP10 pads which are low dust and noise. There was a graph that was wrong because it was for a different caliper where it showed the BP10 pads have a better initial bite than the BP20 and the performance some what flat.
For the last four years they worked adequate like a pair of organic pads for the OEM calipers but as time when on I notice a reduction in braking performance as they got hot during a drive and now fade. I think what happened is as they wore down they lost their thermal capacity and are fading fast.
I am upgrading to the BP20 pads with the drawback of more dust and wear. This is the correct graph for the Powerlite calipers. I did not realize the BP10 would be get progressively worse where the BP20s get better but for the street it's not needed. If I had the stock wheels I think I could do the pad change without removing the wheels.
