as i cant cut a light in bracket racing,i have to index race,which im good at,not all tracks have index,local track has index once a month,heads up is cool and a new thing,no prep lots of wrecks,if you race no prep,make sure you can get it down broadway without breaking loose,street outlaws knows how to get there stuff down broadway,i love heads up,but only will do it on a prep track and index racing
