Vibrating and pulling to one side doesnt sound like boiling to me.
5.1 fluid is seriously not guna boil with your car/those speeds/that circuit unless you're on fire or all your calipers are binding

The pads were smoking when I pulled up after coming off which was a good couple of minutes driving without using the brakes (also made sure to park up with the handbrake off)

If the pedal goes to the floor, that's gotta be air in the system rather than typical fade where you get gas between the pad and disc.

Don't get me wrong, Greenstuffs are wank, but not that wank!

Air coming from boiling the fluid?

Steve, you say you keep having to bleed the system with road only use??

And it was a hard pedal on track but went to the floor once off track???

What did you do to cure it?

I had a garage bleed the system and fill it with 5.1 after my first track event last year when I thought the pedal was a bit spongy. Then I recently bled it again and go a fair bit of air out the system but don't think I got all of it. And now it's back to it was before the last bleeding
It went to the floor on track and wouldn't stop the car, hence the rally stage. Once it cooled down a bit it would stop again.
Want to bleed it again as soon as possible so need to choose between 5.1 or racing fluid (tempted by the racing one as it's blue )
