Hello.

I use my GR86 on the track, and I’ve always had problems with the brakes.
I’ve been thinking about fitting a BBK, but I’m not sure whether I should try installing some brake discs more suited to track use first.

So far, I’ve fitted three sets of standard brake discs, with Ferodo DS1.11, PBS ProTrack and Ferodo DS3.12 pads.
The Ferodo DS1.11 pads cracked and fell apart in pieces; with the PBS and DS3.12 pads, the OEM discs warped badly and the pads wore irregularly.
I do cooling laps; at most I do 1 or 2 hot laps, and then I cool down, but I still have problems with the brakes.
I was going to fit DBA 4000 discs, but I’ve read this post and now I don’t know what to do https://www.gr-zoo.com/threads/avoi...e-the-gr-yaris-in-a-sporty-spirited-way.7342/

Which discs would you recommend? Or should I just go straight for a BBK?

Ola Ola ,No idea the quality for track but most us went with BBK they are reasonable for the price and easy to come by.
 
Im no expert on the 86 platform but my go kart has a beefier caliper than the stock ones on these cars.

I have uprated the pads in mine and they still don't fill me with confidence even on roads on downhil jaunts. There just isnt enough thermal capacity. If i were tracking the car I wouldnt waste any more money on upgrading the standard front brake discs / pads.

Yes, the Godspeed one is a very good option, but the downside is that for the rest of Europe we have to pay customs duties, which makes it quite a bit more expensive.
I had a brake kit like that in mind, but I’m not sure whether the problem would be solved simply by fitting some track-oriented brake discs that provide better cooling, as this would be considerably cheaper than a brake kit.

Hahaha there’s no doubt that this car’s brakes aren’t up to the job. On mountain roads, with good brake pads that can withstand the heat, there’s usually no problem, but on the track there are still plenty of overheating issues...
 
then maybe air cooling kit ?
expensive but cheaper than BBK. other option maybe visit uk the nbuy the kit take it to Spain , or come by ferry and collect it =)

This one
 
I've got DBA 5000 series (330x28) on Reyland bells (using AP Racing hardware) and so far so good with a few hundred hard road miles and an Anglesey track day. OK the car isn't quite as hard on brakes as a GR Yaris would be but my discs look pretty much new still. RP-1 pads and GT3 ducts.

The cracking in that thread is interesting as it's directly between the mounting bolts, I wonder if it's an issue specific to that fitment?
