Got a stock cyclone s. the car is very twitchy, on pvcs the car just keep spinning round and round when throttle is applied. any idea what can i do help solve this problem?

If the pvcs are new try sanding the pvc a little it helped on mine for a bit more grip,and learn to ease the throttle for drifting it takes a while to get used to pvc rims and dont expect to gain much speed with these wheels its not like rubber drift tyres for grip.
also try locking your back diff should help you from spinning out so much

if you have the cyclone drift, it has a oneway in it. and that is what causes the spin

if your shocks are adjustable, loosen up the rear to gain more traction. loosening will let the back end sit and give better control on a slippery surface
