At times I find the car very fast in the early heats, and as the grip comes up not so fast. Car feels perfect but maybe a bit too stuck sometimes. I do use droop to manage temps. But not rollcentre. Does it work the same way as droop, in that if the car is allowed to roll, it generates more heat in the tyre?

Depending on the track, tech v. open, allowing the car to roll more can create more mechanical grip which will optimize the car.
I find that using a car to generate more mechanical grip can help keep the tires cooler. That said, you can find a setup that will have a lot of mechanical grip but wear the tires faster. Or make the tires come in sooner in the run. After this past weekend - that would mean droop ranges in the 5/6/7. To me, the drop ranges in the 3/4/5 range make the car roll more, making the chassis work more and keep the tires cooler. Again all things are not independent. Chassis grip & tire grip are not independent things to dial in and out. They do work together.
A famous r/c pioneer once told me that the three things that matter in our cars is bodies, shocks and tires. Everything else is distant second.
Find the right bodies, work on the dampening and prep tires correct. Never that easy right!

If during your run.. then you might overheating ... otherwise your setup just really needs to be adjusted to handle high grip. My current car kinda sucks when grip is low... but is on point when bite is up (Thanks Larry)

Interestingly, I'm having a similar heat up issue at the moment as well... although namely on the rear of the car. Been running an adaption of Steen's ETS setup, and it just doesn't have enough rear grip in lower traction.
Given we've been spec'd to run a tyre that takes a while to warm up and hold onto temp, (the chrips die down after a few mins!), is proving tricky to hang onto.
To support Mark's point, the biggest change I made this weekend was to tyre prep, simply going from FX2 to LRP Carpet 2 (On asphalt, go figure..), and instantly car was now driveable and more locked down. So don't ever overlook that aspect, after all, those 4 black round things are the only contact with the ground (unless your like me and on your roof... then it's game over
)
Ran out of time to test more this weekend, but by generally making the car softer did seem to help, as did more droop. But the balance was still off, with the rear being very lively, so need to work on that next time out (I think it's a front too soft/rear too hard combo). Setup attached regardless!

I've had similar before though. At TITC, Carpet2 was most stable, mighty gripper a little more aggressive, and the T-cube fastest but so edgey... FX2 got left in the pit-box after one run! Makes me wonder if it's time for a new can...

Good replies on the subject. I need to learn more about additive regime.
On tyre warmers, why would you go shorter or longer on the time, and how do you decide the temperature to warm at?

Additives - run what everyone else at your track runs. Using something different might yield some inconsistent results in the car handling or tire wear. There is no rules here for additives + tire warming. Start with the sauce that is commonly used and experiment with different warming times. Some of the oil based additives perform better with longer heat cycle while 'dryer' solutions just need a couple of minutes to activate. Different compounds will react with the tire compounds in different manners.

Cheers Mark makes a lot of sense, I'll have a better understanding over the outdoor season. I was first time outdoor TC less than a year ago.

Thanks all :-)
I will post later my setup. It's not really different to my latest ones.
The new battery holder are great and no tweak issue with them compared to other brands. Finally the tape come to an end :-)
