Haha, I just did the ABS trick. Its annoying you can't just turn off the ASM, even though I wasn't braking on Daytona at all anyways. Anyways, I just got all god on my first try!
ASM is not the same as ABS.
That's a touch elitist don't you think Savage? I drive a mixture of ABS on OFF or 1, simply because some cars can be driven with it on OFF relatively easily whereas other cars have braking similar in subtly to as you called it 'a bull in a china shop' hence I use ABS at 1.
Just access the RA menu when in race and you can turn off ASM. Prior to doing so I couldn't win. Once I turned ASM off I beat all on my first try by about 2 seconds.
