LouisB,
My local club does'nt allow addertives,i went once,but never again!!with the cars being so powerfull it was impossible to control,these cars really need addertives to drive them at there best,with addertives it's like driving on a train track.i now after drive 50 miles to go to a track that allows addertives,but its worth it-has they drive totally diffrent with addertives,but then again if you have never used it/then you might not miss it,just go easy on the throttle,
ive never had the pleasure of using tyre warmers,so i don't know what diffrence they make.?.
!good luck!
