Thanks
Here are a few things the kit has done for me personally besides it's obvious basic use in telling you when a tire is up to temp:
There can be asymmetries left to right. In my Exige, because the cat is close to the drivers rear tire, that tire runs 30 deg hotter than the passenger side rear. Therefore, this corner gets greasy first in the OEM setup.
Also, it's allowed me to see the affect the forward mounted oil coolers have on bringing tires up to temp and keeping them there. A lot of people have decided to run a single cooler to save weight, but this adds another asymmetry. And the tire is "bathed" in ~10 deg cooler air which hastens the tire shedding its cornering temp.
