There is no easy way to get this one, it simply takes practice. This takes place before a drag race when the game tells you it is time to heat up your tires. Basically what you need to do is keep your rev's within the green section of the tachometer. Rev your engine to the top of the meter, then as it starts to fall, pull the trigger over and over in a really fast motion to try to keep revving within the green part as it gets smaller and lower down on the meter. You will get bonuses as the bar underneath the rev meter gets filled up like the 25%, 50%, 75%, and maximum grip bonus, but none of these really matter in terms of the achievement.

What needs to happen is that when the timer runs out the bar needs to be filled to 100%. Even if you hit 100% (the maximum bonus) earlier in your revs you wont get the achievement unless you finish with the bar at full capacity.

I actually got this achievement while going for the wheelie achievement. All I did was buy the Camero SS and fully upgraded it, after that I entered and easy drag race and when it came to the point when I had to start earning my grip. I'm not sure if it was just this car, but the grip actually went up extremely fast and I was at max grip for about half of the time.
