Indoor setup 2wd

[Alex H]

Hi!
Here in Sweden we have a cup where we only run 2wd cars to keep the costs down.we belive its the "cheepest" class to begin in rc compared to touring which is the biggest class indoors still. But offroad is groving each race. More and more competitors each time. Nothing compared to the U.K standards though.
We have rules that says only one pair rear tyres per race and free front tyres. All are aloud to run modified and we are only aloud to use the schumacher minipin yellow rear tyres. These tyres are much better than the Losi Taperpin we tried last year eventhough there are some other opinions regarding that. we also run solely on carpet.
1. What tyre do you guys use on carpet? Durable and grip?
2. Rideheight. Low or level?
3. Limiters in the shocks?
4. Damper oils. Thick or soft? Springs, hard or soft?.
5. Everything else that you can think of!

I have an atomic s2 and I am alone with that but most guys run B4s and Losis. Lately a couple of RB5s. If you have some magic setups, please post them here for those cars
Hope I made my self clear. Speaking English is a lot easier than writing
