Alignment settings for street/track use

I just changed the rear alignment before the last track day.
Before I had -1.5Camber in the rear and 1/16 total toe in...at that I had outside tire wear and outer tire temps about 15-20 degrees warmer than inside.
I maxed out the camber at -2.6 deg....1/16 total toe in....now my inside tems are about 10-15 degrees warmer than the outside. I am using Falken Azenis. I have been told that 10-15 deg warmer inside on the rear is Good........
Do I need to go back to about -2.2degrees camber ???? Or is that temp differential OK

My alignment specs are here.

Corner weight balance you do but 70kg will not change the camber or toe angle will it?

for racing every thing count so driver sitting inside while doing alignment.
I've seen some of them making 0.2 camber differene (depend on your suspension), and you know once the camber change the toe change too, but if it's only for track event then is ok to skip this step.

Looking at tyre wear, depends on track, I would say. Even tyre temp, I think is the way to go.
Is your falken softer on the outside rather than inside... the temp depends on tyre too!

shoot the temp on three spot, inside, middle and outside.
inside temp higher = less camber
middle temp higher = on the right spot
outside temp higher = more camber
inside temp higher = less camber
middle temp higher = on the right spot
outside temp higher = more camber

I use one of those before, you have to hold the needle for a 6-7 second to get a good reading, not good beacuse it takes too long for the first tire while the others cool down. the best time is do a good clean lap, then come into the hot pit and measure, and it is better getting the infrared laser thermometer fast and easy to use.

The reading on a probe type will be much more accurate than an infra red for tires. The outer surface that the IR reads cools very rapidly when you stop...while the core temp that the probe checks is much slower to cool.
IR works great for brakes and radiators, A/C..intake etc....but don't work well for tires

Ideally you would be measuring the temps immediately after some steady-state cornering - any straight-line driving will cool the outsides of the tires and continue to heat the insides (Because of the camber, the inside of the tire is more highly loaded when not cornering) - and those temperatures would be even. I'm guessing though that the temps you all are taking are after coming into the pits, and you probably didn't just finish a hard corner to get there. A 10 degree rise in this case is just fine.

you have to go out side drive a few laps and when you feel that you did a clean lap (no traffic and no spin out or off track) you came into the hot pit and let your friend take your tire temp inside the hot pit. not after the section is finish.
my bad, on the IR, I am wrong.

I will go to the track, because I want to put these on my car.
Look cool
