Default T4 stadium truck carpet setup problem

Hey guys, ive been racing a T4 stadium truck on the carpet all winter with results that are not very good.
We are racing on carpet, we must use foam tires, and a stock 21 turn motor.
The problem i am having is steering, it scrubbs and wheel hops and generally "pushes" into turns mostly only when turning Left. The right turns arent too bad. Ive tried changing shock angles, shock stiffness in front and back and im just not getting anywhere, and ideas?

it will be because you are running foam tyres, are the wheels that the foams mounted to official associated T4 wheels, if not that will mess it straight up, and it will take a lot to fix, if you can fix it, i reccomend mount your foams on T4 wheels and try that

Are you using traction compound? Did you lower your truck?

I used the jayco foam tires already mounted to wheels, that came from tower hobbies. I am putting sauce on the back tires, and a small rim on the outer edge of the front tires.
I am sure perplexed about this problem.

Most call it tire sauce.

You should try to true the tires, that might help or ask at the track, I'm sure alot of people have had that same issue with their T4's.

i would try some T4 wheels & tyres, if it still does the same thing, you know it is the truck's set up, if not, it will be the wheels
keep us posted

the track does not allow rubber tires on the carpet. And its a new class and we only have 3 trucks now.

well in that case the only thing i can think of, is try and get some foam to put on your T4 wheels

Have you experimented with your tire sauce coverage? Like maybe only doping half the width of the rears to try to eliminate the push? Or since your problem is in lefthand turns you could maybe try a ring of sauce on the outside of the left front and a ring on the inside of the right front.

I'm dealing with similar issues on my carpet 18R. I went from sliding around like on ice to traction rolls on the big corners so am still hunting for the optimum tire juice patterns.

You should try to convince the owners to use the Panther slicks on the track. If you guys stop racing there then he will lose money. Anyway, your just gonna have to work with stuff, try a really thick oil in the rear and front shocks. I know a guy who put on-road srpings and 80wt oil in a Revo and it handled exactly like a truggy. Good luck.
