If you want to keep the drag radials then try lowering the air pressure to 15psi and smoke the shit out of them in the waterbox. Also make the rear shocks stiffer if you can. Anything you can do to make it stiff in the back will help depending on the track condition(if the track is too slippery it wont help as much). You will still have loss of traction in first but that's where you'll have to peddle the throttle to make it hook up. Once it hooks it should hook in second gear too. Good luck.
