dusty
so track is dusty.. you meant it has loose dirt? is there any hard packing? what type of dirt.. is it smooth or bumpy? if its hard packed, no loose dirt.. then i suggest run smaller tread tires.. like proline holeshot... if its got some hard pack, and some loose on outside.. and the track is soft.. i would use tires like proline bowties or crime fighters.. though i say you gotta buy a couple different tires try see which one fits your driving habit. Most of all it also could be the suspnesion setup.. such as chambering while suspension plays up n down.. sway bars, shocks, height ride, and toe in n out.
