With Rotary's point Tanner's car has a NASCAR V8 under the hood. That thing has so much torque he has to jam the widest tires he can on it to have a possibility of control, not to mention the whole "purpose built race car" thing.
Look at the guys like Mad Mike Whiddett, or Matt Powers if you want to see the "style" stuff. The guys in there with big sponsors that don't wrench on thier own cars aren't the guys that everyone shows up to watch. The guys we want to see and are cheering for are the guys with blood sweat and tears into thier car. The sport would fail if it weren't for the little guys that are still about style in my opinion. The whole sport is based on style, cars like Sam Hubinette's Dodge Challenger look like sore thumbs. If you spend NO time working on style and everything on engineering the best car in a series based on style no one will root for you. Sure he's a good driver, but I can see a car like at the dealership. Big MEH, not interesting to look at, watch, and doesn't draw you in. At least Tanner's car is widebody and some cool engineering went into converting it to RWD. It's not all about the tire stretch, it's just one of many factors of style.
