The key to running on asphalt is tires and traction compound. On our somewhat clean tracks here in FL we run pink or double pink rears and double pink fronts. White rears will wear out in one run.
For traction compound the best thing to do is Paragon Ground FX for 15 min on the whole rear and inside 1/3rd of the fronts followed by suntan lotion over the same ares for another 15 min. Just put a layer so its coated and you cant see the foam through it. In 15 min most of the suntan lotion will dissolve and soak into the tire. Before running just wipe the tires off really well and you will be amazed.
Running just Paragon will pick up a lot of dust. The suntan lotions stops that and dramatically improves traction on dusty parking lots.
I have been running pan cars (Pro-10, 1/12 and now WGT) on asphalt since 1988 and no one has ever come up with a better traction compound treatment than paragon and suntan lotion.
