practice launching and get the tire pressure adjusted so you get an equally dark, full tire width patch of black rubber on the pavement,too little air pressure usually makes the outer edges darker, to much air pressure usually tends to make the center of the tire marks darker

AS a general rule, a performance street cars rear gear ratio multiplied by the transmissions first gear ratio should fall in the 10:1-10.5:1 range with tire diameters in the 25"-28" diam. range
