    Question eBay TPMS for trackdays

    Does anyone run aftermarket TPMS on their track car?

    Thinking about those you mount inside the rim on the valve stem.
    Found a cheap kit on ebay, but it says temperature range -40 to 125C (-40 to 257F).
    I mainly want it for the pressure monitoring, the air-temp inside the tire isn't that interesting

    How hot does it get inside the rim? I know the brakes get red-hot, but how much of that heat radiates to the rim?
    Don't want to buy a kit only to cook it to death on the first trackday

    I've been using this style. So far so good, although they are a little slow to display changes in pressure.

    I've eyed this setup - the low mass sensors seem beneficial compared to others. Great to hear it's working out.

    How fast are the display updates?

    Do you use it with metal valve stems, any foreseeable issues with rubber stems?

    I take this kit is really only appropriate on wheels with two valve stems? (caps have locking nut, right?)

    I guess those would work to, but I don't exactly know why, but they always seem a bit flimsy to me...
    And on a daily driver, I'm pretty sure mine would get stolen rather quick

    5 minutes or so maybe. I haven't been looking closely. Metal stems, rubber should be fine. Works fine with a single valve stem.
