XRAY - Model racing cars

What is the ideal size you find your foams to work best?

Here is what I have found thus far:

Ones right from the package cause too much traction roll even adjusting ride height to compensate. Once the tires reach about 35.2mm and below is when the car really starts becoming consistent with traction. 33.9mm is when they really seem to hook up the best. Once the tires reach under 32mm, they drop off quickly.

What have you all come up with?

I would agree that 33.5 to 34.5 mm is a great range to race in, however my car felt most responsive closer to 34.2mm. Too small and the car felt slower but that can be a rollout issue.

Car definitely feels smoother and more planted with trued foams.

Bump. Good info to share for new users.

We have tested tires now on our track a little more now. And rear 35 and front 45 workes best.

But the fun is the traction roll. Its not rollig of the "traction" as you may think. It is rolling because the rear tires looses grip, drift a little and roll the car. So we testet traction additive all away round the rear tires. And now the cars are REALY fast. Filip drives 35 rear with traction additive and 45 front. And the tires is about 33-34mm, outer edge a little rounded.

My car dit not work with the 45 front last time, so i drive 50 front 35 rear. traction additive all the way both front and rear.
