Can anyone explain this modifier? Why do these cars get a +0.2? With the limited modifiers, this one doesn't seam that important to overall performance. There are plenty of performance cars out that are 4 or 5 doors. What inherent handicap do they have?
I can see that they are typically heavier....but that's handled my other means in the ST/TT# classes.
I have heard people argue they are not as stiff, but I can't see that mattering in a full prep car. Seriously competitive cars are likely going to be caged, solving the stiffness issue. Also, most cars built in the last 20 years are soooo much stiffer than the old stuff, the net handicap is insignificant. Some 4/5-doors are actually stiffer.

Other reasons? (other than because you have a 4/5 door ;)

It might be aero or height / CG related. With BMWs, the sedan is sometimes taller and/or narrower.

However, sedan can be just as stiff or stiffer than a coupe due to better b pillar placement.

But there's at least one EVO out there killing everyone and setting track records like it's its job. Sedan allowance certainly helps...

4 door spec e46's seem to be just as competitive as the 2 doors. Pretty good comparison, because they are spec cars.
