·For what it's worth...
I only use my Stage 1 tuned EVO6 on track days. And I brake HARD. The original brakes failed - completely - within one session at Bedford Autodrome. Oh dear.
I changed the fluid for Castrol SRF. Never lost the brakes since. ...But the brakes then 'wobbled' at the steering wheel like a complete *******. The car was virtually useless as a track day tool.
I replaced the Brembo disks with Tar-ox grooved (£220/pair) and Mintex 1144 pads. Much better 'bite' and far less 'wobble', but still some. Bugger. (BTW, my brother-in-laws brand new AP 6 pots on his EVO 6 also wobble a bit when hot...)
Took the 'dust' covers off from behind the front disks to stop the heat build-up. Also put in short sections of piping to cool the brakes. Brakes *much* improved on the next track day, but still not perfect.
Finally, put in two long lengths of Silicone 50mm hosing (Demon Tweeks) from the front air dam (after removing the daft lower air boxes which do sweet F.A.) and have them blowing between the caliper and the disk. Have done Brands Indie (OK, not that hard a circuit on brakes) and today I did Goodwood, hammering the brakes hard, hard, hard all day on 8 sessions. Not a single 'wobble' of any kind, nothing, nada, no matter how hard I proved the brakes - i.e. front tyres loosing grip.
This reinforces my belief that with decent - but not mega expensive disks and PROPER COOLING you can get great brakes on a EVO 6. The 1 million or so threads around here about 'warped disks' are wrong, IMHO. (Cue flames! But read the excellent post the other day about 'the warped disks myth' first, and the wobble stories that people get even with the CTF and AP disks...). Sure, if you are driving 11 tenths, in a 400BHP EVO, and are racing the bloody thing in 1 hour long sessions|PLS|, then AP/Movit |PLS| COOLING may be the only way for you. Me? I just wanted good, wobble-free brakes for hard track use. Now I have that, and without shelling out nearly £2k on AP's...
If you think the above is 'bull' or 'not for you' or 'disagree' then fine. I'm just trying to report my OWN real-world experiences. I hope the above is of use to any other EVO 6 owners who use their cars on track days and want to get rid of the dreaded 'brake wobble' that I experienced. This was the only thing spoiling an otherwise excellent car. And now it's sorted, I can look forward to my summer of track days.
Cheers,
Steve
