I was thinking that I probably need stiffer side springs...is this correct or is there something else that I should try first? In any other form of racing you'd have the option of tightening the diff but the manual says that in 1/12 scale racing it is critical to have the diff as loose as possible without slipping.
With harder side springs the car will "feel" easyer but tent's to lift it's rear wheels faster. Try running softer side springs and also a softer center spring.
The softer side springs will make the care lift it's wheel less easy. The softer center spring will slow down the weight transfer and there fore lift the wheels also less easy. But softening the side springs will make a set-up changes and maybe loose some reaction. If you don't like that make the side tubes a litte stiffer.
Also try to drive les camber at the front wheels (1deg) and try putting some sticky stuff on the front susp shafts (under the front springs). This will also slow down the weight transfer. Less but not least put the battery in front (if not already there) and just try to "corner" easyer, try some steering curve (-10%).
I assume you have already widend the front end (168mm / 169mm) and glued the front tires?
Good luck!
Best Regards
