Driver mod? Haha stg 1 on these cars is hardly worth noting really bad wheel spin. They spin in first and just some in second. First gear you cant really do anything, by time you have "modulated" the trottle its already time to shift, and in second if you feather the gas you'll end up being slower than you would if you had just floored it and ran the tires. Get a car that will spin through the top of fourth and then you'll really understand how to feather the throttle. The best thing at this point that you can do is get better tires, its as simple as that, feathering the throttle on shitty tires is useless.
