Best - Simplest way to fix the Supra for tracking?

Also TPMS only updates every 15 secs or so. I would get less than four updates per lap at LRP. Basically useless.

Less button/clicky things to remember to turn off before going on track.

Below 25psi the TPMS would turn TC back on while driving to the hot pits and then I would need to remember to turn TC back off before going on track.

If you do the TPMS learn with the tires at cold starting pressure it doesn't care and will use that as your "ok" pressure. I do agree that it's an extra step, but I like having the temp sensor info it provides since it gives a good indication of when things are getting too hot. I've found on the 71RZ as the temp sensor goes above about 150 I shouldn't start another flying lap, and when I get them below 140ish from cooldown laps I "should" have enough capacity to run another hot lap.

When I swap to the track wheels I usually do the learn procedure at 25 psi so I don't have issues later.

Yes, that won't help when it drops below 25psi between sessions. I ain't driving around the pits for 5 minutes to have it learn again before a session.

The 15 sec update per data point also doesn't work for me. Basically useless.

I wonder if it changed between model years then. I was at VIR this past March and drove around at 25-27 psi to set it and it gave zero warnings when the tires were at 22-24 later that night. For 2026 it seems like it has the standard 5 psi buffer from the setting you give it.

Might not be useful for you, but it's still helpful for others to give guidelines on pressure and temp. I know I used it at LRP after down hill just to check general tire temps down the straight to know how hard to push on the next lap. 3 updates per lap is still better than 0.

He asked me why. I told him why. My why. I even literally stated it doesn't work for me. I don't give a fuck what others do. Go full ham.

Yep, I get he quoted your post and asked why. Since this is a public message board I thought the OP might find it useful to see a counter point on how someone else does find it useful.

As someone who says they don't give a fuck, you sure do give a lot of fucks when someone has a different point of view

You sure give a lot of fucks to argue for no fucking reason other than to argue. And... put on ignore. Zero tolerance for fucks now.

I was wondering why my TC was turning back on since I've been playing with the pressures on my 71RZ's. Thanks for the insight.

In my short experience (3 track days) with the RZ's, they seemed to do better with around 31-32 hot vs 34.

hmm, didn't know the freq was that low. i was using it to keep an eye on the temps for the most part.

Every forum has a resident douche bag.

Start simple with tires and pressures. Even with a set of re71rz’s being a few pounds too low feels pretty bad.

Tires are the most essential and primary focus.
