could you explain what the car does going in the corner....middle of the corner and going out of the corners?
IMO 25 shore is too soft and you loose all balance in the car to get any sort of steering back in. I don't know but i can imagine the tire is even rolling under itself cause of the softness. A body doesn't do that much in a slow corner so going to a sophia doesn't cure that problem. IMO first look for a balanced setup for the slow corners. Once you get the car set up for the slow corners i would go to find the solutions for the fast sweepers.
I helped westy1969 on here with his crc genx10 last friday evening. Our class 2s lipo and 10.5t open esc. Our clubraces are in the evening so traction is very low. Together with a very large sweeper (wich you can take full throttle) the straight is over 330 feet (over 100 meters). After the straigth there is a very tight 180degree turn wich you need to break for otherwise your into a fence
During the evening there is some condensation going on making the traction very bad at the begining of the season. He didn't use traction compound cause it was just a try out but after some directions (correcting his TC driving skills
) and a little tweaking on his chassis setup he could drive the car quite ballanced around the track. There was some spinning out of the slower sections but it was predictable so he could catch it and countersteer without having to go too slow in the slower corners.
After 2 times hitting the track with some setup changes the car went quite well, considering that even the TC's had traction problems and he wasn't using any traction compound.
As this was the first time he really had a chance to drive the car, there is still a huge amount of margin to get the car even better.
I don't remember the setup by heart but westy could shim in on his setup.
car standard 200mm wide don't know exactly what width the front and back is
purple front tires, no traction compound(jaco or similar)
Pink backtires, no traction compound (jaco or similar)
35wt (don't remember the brand)
red tamiya spring
green side springs i think (he had white first)
corally hard spooch (no idea what cst that is)
we changed the poddroop considerable so it had less poddroop then it had first... don't know how much it is now
ride height 6mm all round i think
