Race Tracking Your Supra - Information exchange

[Rob_SER]

The PMU 999s are shockingly good



The heat down here right now on track is well over 120. Amazing you can do it. Definitely younger than me ?

Bryan is usually right. I did low grit sandpaper one older set and that helped. But didn't get much from the rotors after that. Started to show a lip. So, I'm back to just buying a new set of front rotors when it's time. The rear just doesn't need changing nearly as often. Hence buy rotors when they get new pads as well.



Can't remember, did you try SRF? Doubt I'll ever go back to anything else

yeah i'm running Castrol SRF

The August track day weather was actually amazing!(for Florida summer) Just got the new rotors in yesterday, going to take them with me to the next track day and replace them there if I really need to.

Reminder to check your diff bushings.

Great reminder!!! That particular part says not for the Supra. Is that the same one we can all use? I’d rather have it for not if but when they go out.

Yes it’s direct fit. G2x rear diff bushing is the same as the F8x/G8x. They don’t make front bushings as of yet.

I supplied another manufacture with measurements, don’t know when they might make them. My front mounts were fine, I just filled the voids with urethane for the time being.

If I can't get on top of the issue quickly, I might try the Endless ME20 next year.

Endless pads are stupid cheap at the moment from Blackhawk Japan and RHD Japan btw — the weakness of the Yen and all... about half of what they cost from US retailers, even after shipping.

The Mu of the ME20’s end (.40) where the PMU’s start (.42-.55)

seem like not even close to a comparable pad

As long as they don't fade I don't really care... My first impression of the club racers is they are very capricious, never had so many issues with a track pad...

Went for a track day yesterday, hard braking, smoking pads and blue rotors, still vibrations... Not as bad as my first track day but still very noticeable. I guess a good test could be a new set of rotors...

Doesn't help that Endless USA & Endless JP list wildly different pad mu's the ME20.

Endless USA lists 0.45-0.52 while Endless JP lists 0.35-0.40

Found some Verkline bushings. Heard good things about them as well

Yeah, if you get rain, which you should - it’s phenomenal! Just my luck the few times I’ve been and didn’t.… ?

I don’t see any offerings for the differential. The bushings they offer are to replace the 2 remaining rubber bushings on the rear suspension once you’ve upgraded all the arms.

It seems to be that shudder is actually some type of minor abs activation that needs to be fixed.

 

[Rob_SER]

Woah ok, that's crazy...

I wonder if that's really the issue why we don't hear about it everywhere?

Because this is a recent development that has been resolved by a really *really* smart dude. It's not something that's recommended to all, as it’s still in testing.
