thats sounds like a good launch.looks like you need smaller tyres.but how much smaller.there will be a ratio as per inch in tyres as to affecting rpm at the line.i dont know what it is.for example if 1 inch down gives you 200 rpm, at the line you need to go down 3 inches to pick up 600 rpm.have you got any 14inch rims and tyres you could try
