There are only two road courses on the NASCAR circuit. In the past it used to be the 'road course ringers' that were brought in by teams to replace their regular 'go fast, turn left' driver. Not so anymore. Although some 'ringers' still run for a few start-up teams or those flirting with falling out of the top-35 in points, most all of the NASCAR regulars have gotten adept at racing the road courses.

These four 'flat' tracks range in banking from 2° to 14° and vary in length from .526 miles to 1.058 miles. And while not a universal statement of 'good at one then good at all' of these tracks is true, the relative similar flatness of these tracks does create a similar racing style and patience needed by the driver. As well, it is important that the teams hit on the set-up of the car to give it the ability to turn well in the turns.

These two tracks are shallow-banked, but they're much larger than the 'Flat Banked' group, so they warrant their own category. The Brickyard in Indy obviously requires a lot of horsepower, but it's a shallow-banked place, so it's not at all an equivalent of your superspeedways. Pocono is a tri-cornered place set up to run partly like a speedway and partly like a road course; teams tend to set their cars up to work best off of Turn 3, the 6-degree turn, which is why we find that racers who do well at shallow Indy tend to do well at Pocono.

Steep tracks that don't adhere to the cookie-cutter formula, and they're certainly the loosest group on this list. Bristol is often referred to as a "mini-Dover" (or, rather, Dover is referred to as a "Big Bristol"); at 36 degrees, Bristol is the steepest-banked joint on the circuit. Dover is concrete, and the high torque and aggressive driving styles that work on one usually work on the other. Same for the new configuration of Homestead, which used to be a flat track, but acquired some steep corners a few years ago. That grouping of three has worked pretty well for us in the past. The wild cards here are Darlington and Las Vegas. Darlington is definitely steep-banked enough to qualify for this group, but its sandpaper racing surface and difficult, narrow exits out of the turns make it its own animal. Darlington also encourages sliding out of the corners, which gives it something in common with Texas, among others. Meanwhile, like Homestead, Las Vegas Motor Speedway used to be a flat track, until its owners rebuilt the track's turns in the fall of '06. Now its configuration is something like the new Homestead.

Other than perhaps the road courses and superspeedways, this is the tightest grouping, because these cousin cookie-cutters are damn well near identical. If a guy dominates one, it's often safe to assume he's going to perform quite well at the others.

This isn't a straight-up fivesome. The tracks which bear the most similarity are the two 2-milers, Fontana and Michigan. They're both Penske creations, and while the Fontana venue doesn't get the winters that the Michigan track does, they still ride relatively similarly. Kentucky and Chicagoland both have single events each year, and are basically stand-alone tracks. Kansas and Kentucky bear a semi-strong resemblance to Chicagoland, and a somewhat fainter resemblance to Fontana, while Chicagoland bears a semi-strong resemblance to Kansas and Kentucky, and a somewhat fainter resemblance to Michigan. Yes, Kansas, Kentucky and Chicagoland are all 1.5-milers, but they really don't resemble the Atlanta-Charlotte-Texas triumvirate.
