Default Track brake upgrade

All

I’m looking to run my C2 on a track day with the only upgrade to the brakes being a switch to EBC yellow stuff track pads, or something similar. Does anyone have any experience of using the standard 964 brake set up + track pads on a circuit i.e. does upgrading just the pads work or are there any other issues to look out for? (fluid has recently been changed).

Probably worth mentioning my car’s a 92 car so has the four pot calipers at the back as opposed to the twin pots on the earlier cars.

Thanks for your help!

Cheers

Stuart

Add high boiling point race brake fluid and your fine.

My brake set up is standard 4 pots front and rear. They work fine on track. Don't do more than a 15 minute session at a time, then a cool down lap without using the brakes and rest the car for 20 minutes and they'll last all day.

It's debatable if EBC yellows are any better than standard textars. There are pads that are significantly better, like Pagid RS29s, if you're willing to spend the extra.

As the others have mentioned hi quality fluid, braided hoses and decent pads and you're all set. Imho ebc yellows are not decent pads but at least they don't overheat. As boxey said Pagid RS29's are much better. From what I hear there are also other good options but I haven't tried them.

The usual mod is using C4 calipers.

2 pots worked but I managed to boil the fluid with mine. The small pad really concentrates the heat back to the caliper. You also have very little choice in pad types. Switching to 4 pots gives you a bigger pad to disperse the heat more and you get a much wider choice of pads.

For the upgrade to 4 pots you use the same rotors and then use rear calipers from either 964C4, 993C4, 928S4, 968 or 944 turbo. The last three require you to swap the bleed valves and feed pipes before fitting. Here's my write up on the upgrade for reference:

If you're lucky you won't have to do all the spring plate re-furbing that I did on mine.

+1 on Boxsey's recommendations, and Farnk's point about higher boiling point fluid.

EBC yellow will be ok if you're new to trackdays and do short runs, but thereafter I'd rather run an OEM pad as they do tend to overheat and glaze and then you really need to let them cool down to get any braking back....and if you're really serious then you'l be into drilled (or preferably slotted) discs and something like

      Then you're into things like brake ducts, etc

      What trackday you doing and when?

      Thanks, am fairly up to speed with track/test days in general but have not run a 964 on the track before so was thinking of Bedford initially.

      It's mainly a road car but I plan to do a few track days just to get a feel for the car rather than make a habit of it so don't want to upgrade the whole system, just make some sensible mods to avoid fade mainly - previously I ran a 600kg Caterham so never had to think about brakes overheating!

      Let me know when you're doing Bedford and if I can I'll swing by..

      600kg Caterham....heavyweight!

      My Westy is about 480kg, before I get in !!!!

      Sounds good, will give you a buzz when I sort something.

      600kg was with me in although 480's pretty fly weight, I guess you're properly familiar with lift off oversteer if its anything like the Caterham!

      I upgraded from the 2 pot to the 4 pot, and it made a big difference. No problems with the upgrade. Mine are silver 993 calipers, but they are the same as the 964 calipers.

      I use Pagid pads, Orange and Black, don't remember which I have on front and rear right now. They work very good.

      It is key to use a high temperature brake fluid. I use racing blue.

      Good luck.

      I also upgraded to 4-pots. One big reason was that I couldn't find good 2-pot track pads. I use PF97's, hi-temp Motul 6000 fluid with braded hoses.
