Hi,
I'm curious, has anyone used an aftermarket TPMS whilst out on track?

If so did it give accurate temps and pressures?

These come in 2 forms. One t replaced the valve and the sensor sits in the wheel and the other replaces the dust cap and they feed back to a display on the dash.

Thought it could be useful?

I used to use the factory TPMS on my 2009 Cobalt SS to monitor when I needed to take air out after the tires got hot.   The TPMS was surprisingly accurate and responsive, but I would only use it to know when to check with a real gauge and do tire temperatures.  The Cobalt turbo was a fast, cheap track car I had here in Canada and it had a configurable display on the A pillar.  I usually had the display set to tire pressures, g forces and kph.  It could display a bunch of things, but this was usually most useful. 

It was a good thing as it came built with the car.  Personally I wouldn't invest in putting one in aftermarket as I would rather take tire temps across the tire surface.  With the Speedster I just stop, check and have a feel for how the car responds on a track. The Speedster of course is a lot easier on tires than the Cobalt.
