Just a thought but..isnt that what racing is all about?..to have to fine tune youre car to the tracks changing?..whether its outside or inside..asphalt changes with changes in temp and humidity..and you will need to set youre car up right..carpet stays the same..seems like slot car racing..the same grip everytime...just an observation..but for Me..I think that having to "tune" the car to a changing track is part of the fun...
