Yes, only on certain tracks and pads. If they start wearing uneven, they can move at the bottom side toward the hub and just slightly touch the rotor with high G load and cause that sound. Test it by moving a pad pair to the other side of the car. That is how I figured it out.
I would highly discourage using spacers with no wheel centric lip for track use. 3 and 5mm spacers (And almost all 10mm) do not have this, and depending on your wheel center bore design, the wheel might have nothing on the hub lip. 12mm+ do.
I would also discourage MH studs, they are very low...
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.
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.
Most Super200's I have found are happy at 32psi hot. I usually go out on 25-26 cold, and have done PB's at below approx 30psi.
I have long since ditched TPMS on my Supra but here is an example on my boat anchor 4000lb M240i:
The torque solution arms are basically a 1:1 copy of the SPL arms, so same issue(s) apply.
All Torque Solution products are basically 1:1 copies of things.
