Have you been trying to find the best setups in Nascar Heat 5 and feeling confused or stuck? We fully understand the importance of having a high-quality NASCAR Xfinity setup on NH5, specifically when using a sophisticated circuit like the Atlanta. 
Pushing through each lap with full throttle will be crucial if aiming to break into the low 29’s mark. You will need to run a negative 3.0 camber in the front right, while in the front left a positive 3 camber and wheel lock of approximately 12 degrees. The position on the left wheel where there is a high positive camber will greatly assist you during the time when you are trying to make the initial turn-in, and the position of negative camber on the right wheel will assist the mid-corner grip phase which has maximum lateral load on the tires. 
Adjusting the front swaybar to a stiff position of around 1.675 should allow a good midcorner rotation without disturbing the rear too much on turn in. It is really essential to have the backend behave in such a manner which does not require you to let go off the throttle, in essence preventing too much oversteer in the vehicle. 
For instance, when you start your drive it is important to have a slipstream because on the drafting you can save as much as 2 to 3 tenths of a second! But as I have said, that is always quite tough to time, so if you end up missing out on getting a good one, do not fret too much over it.
