further developments...
Thanks to all for the advice on this grip roll subject. I replaced the front springs with harder springs and this really improved the handling of the car and I no longer suffer with grip roll :-). However at the same time I also had to change the diff spur gear as i'd inadvertantly stripped the existing gear during my last race. This has resulted in an even higher gear ratio than previous but I am now experiencing a "hopping" motion during initial accelleration? Now is this due to the ridculously high gear ratio 16/72=4.5 from previous 16/80=5 or is it due to the reduced /changed weight transfer due to the harder front springs? Or is it just the tyres losing grip/spinning up due to low traction from cold? I can say the "hopping" effect happened at the end of the race as well as off the line so maybe nothing to do with cold tyres.
Do I need to stiffen the rear springs now to compensate for the stiffer front springs? Or should i just put traction additive on the rears to improve grip?
Any comments welcomed
