Thanks for your time.F1 still rocks more then ever.
Although I don't own a FGX, but I learned a lot of tips from various FGX racers.
For the tires, you'll probably be better running stiffer side walled at high traction technical circuit like TQ. The constant turning and gripping is pretty stressful for the tire side wall.
Speaking from F104 perspective, some of us use different rims for the same type of Pits tires. The foam rims are good for outdoor where grip isn't high and bumpy, because the softer sidewall absorbs a lot of the bumps and also the flexing side wall makes the tire grip better. Then we have the Pits on the standard F104 rubber rim with the outermost ridge grinded off. See
http://www.rctech.net/forum/10130806-post93.html for details. This makes the side wall firm, and also makes the car responsive and tire doesn't collapse (or fold) easily during high grip technical circuit like TQ. However, it quite a pain to grind and glue properly.
There are various racers still developing ways to optimize the tire side wall for FGX on the Pits. Hopefully when a good solution is found, it can be posted for everyone.
But for the upcoming race at Speedtech, the softer side wall will probably have a better advantage.
