Do the crew chiefs set up the cars the same for both tracks?</h2>\n\n<p><img src=\"/images/misc/px.gif\" width=\"400\" height=\"1\" alt=\"\" />- submitted by Dale8fan</p>\n\n<p>A: Hi Dale8fan.  The answer is no.  The tracks may be similar in length at quarter mile but Bristol is steeply banked, more so than even Daytona.  Martinsville is a relatively flat track with not much banking in the corner.  Lap times run four to five seconds faster in Bristol where the cars slam off hard in the corners and crew chiefs fight to keep their suspensions from bottoming out.  In Martinsville, the cars tend to float more in the corners and the crew chiefs can run softer springs in the front.  The gear ratios are a big difference, too, as crew chiefs run about a 6:50 gear at Martinsville and a 5:43 at Bristol.  The one thing that is common to both tracks is that the drivers can be aggressive on the gas in the middle of the corners.  Martinsville should be a great race as tensions spill over from Bristol!</p>\n\n";

My question is what do the crew chiefs mean when they talk about positive and negative camber on the cars? </h2>\n\n<p>\n<img src=\"/images/misc/px.gif\" width=\"400\" height=\"1\" alt=\"\" />- Submitted by: TonyRocks\n</p>\n\n<p>\nA: I&#8217;m glad you asked that question because a crew chief uses these terms on a daily basis.  Positive camber means that a tire is tilted outward (away from the engine) at the top and negative camber is just the opposite where the tire is tilted inward.  The teams run camber in a car to get the car to &#8220;bite&#8221; in the corners so when the suspension travels the full footprint of the tires contacts the track.\n</p>\n\n<p>\nMost teams run positive camber (leaning out) on the left front tire and negative camber (leaning in) on the right front for the majority of the tracks on the circuit with the exception of the two road courses that NASCAR runs during the season.  The crew chiefs will run negative camber on both front tires for those road courses.\n</p>\n\n<p>\nThe last thing I want to mention is that crew chiefs run the risk of running too much negative camber on some track and what that does is on the straights the right front tire has very little contact with the track mostly on the inside edge.  That&#8217;s why you see some teams blowing out right front tires on speedways.\n</p>\n\n<p>\nThe last thing I want to mention is that crew chiefs run the risk of running too much negative camber on some track and what that does is on the straights the right front tire has very little contact with the track mostly on the inside edge.

When the car is somewhat in clean air, it is able to take full advantage of the front down force the car has. When it gets close to the rear of another car, it looses some of the front down force, because the car it is behind is taking the clean air off the nose of the car, therefore the car will not turn as good, and we call that aero push. The only thing a crew chief can do to help this is when you are working with the car in practice, make the car turn more mechanically/chassis wise, than with aero/front down force. The car chassis wise doesn&#8217;t know if it&#8217;s in clean air, or behind or in front of another car:  \n</p>\n\n";

But because of how small the rear spoiler is, (4 1/2&#34; tall x 55&#34; wide), teams pretty much every where run it at maximum angle, which is roughly 70 to 75 degrees. For the 2 restrictor plate tracks, they not only mandate the size (6 3/4&#34; tall x 57&#34; wide), they do also enforce a minimum angle of 55 degrees, which they do enforce very closely, knowing every bit of less angle would significantly help the speed of the car (reduce the aero drag).</p>";
