i'm on a 4/10 mile, medium banked, 'd' shaped, paved oval. it's a monster for a kart, but awesome for a super late model. turn one/two is tight heading ontoo the back stretch, but you can get set for three/four easily. coming out of four is a trick! it's a sharp "snap" to get down the front straight and get a good angle on turn one. the start finish line is on the straight part of the "D". we don't allow running in the upper groove because the tower can't see the karts, so you have to snap it down from floating toward the wall....one the back stretch tho....you cna hang it out there and get some good speed heading into three!! our heats are 6 laps and the feature is from 10 to 15 depending on what the track wants to run (usually the 15 lap features are to make up for other classes that aren't being run). we run WOT from the drop of the green and running 16 ounces keeps everything nice and lubbed!
