Forget the rotating mass issue. When your that good you can notice things like different wheel weight, you don't need to be asking questions on here
Just find the wheels that last longest for you. I've used Sorex, Speedmind, Tamiya, and Muchmore wheels. I crack them all because I drive hard, and hit things hard

What about roll centre?

it occurred to me that if soft springs in the front produces less grip i might need to get the front roll centre down in the front.

right now the roll centre is marginally higher in the front than in the back.
i have anti squat in the back to make it stick on corner exit.
thats the theory anyway.

Soft springs and low roll centre generate MORE grip.

You seem obsessed with getting temperature into the WRONG set of tyres, when really you should be getting your car onto the RIGHT set of tyres, and working on the actual handling, not what the thermometer is telling you.

Tires is what wins or loses a race son
Sosidge is right. I NEVER check tire temps. I change my set-up based on what the car is doing on the track, not how hot the tires are. THe only thing I consider with tires hardness, is track temp. The rest of my set-up has little to do with making the tires hot.

Reading through this thread makes me think about what happened to me recently when using high roll centre and soft springs, oil and 6mm ride height and jaco blues.

After running the car, I noticed that grip overall decreased and I couldn't figure out why. Then I take the car off the track and I see the tires have funny marks all over them. At first I thought, the tires were crap, but then I switched to another set, and surprise the same marks appear after about two runs.

At the same time they are soo sticky, they are picking up carpet fibers.

Now I realize that the tires were getting too hot, causing the marks to show up and loosing grip overall.

All this because the static roll centre was near ground level. Calculated using the roll centre program.
