the brake thing has a few huge potential upsides.

1 - increased partiy. currently chassis can be chosen as much for their handling characteristics as they can for their ability to bolt on stoppers and drop in motors. 2.0L cars will be HEAVY and bigger brakes will make them more attractive - more cars become "competitive", at least in theory. Also, you will have a good variety of pads available no matter what car you choose, and they will be lower cost. no more shipping pad backings to carbotech for custom rears on the fugizit. just get the superlight compound of your choosing.

2 - simplification. and it's not expensive after the buy in. pretty much like everything else in the class.

3 - category cohesiveness. STL DOESN'T LOOK like ST. it looks like IT. this will take it a step towards matching its bigger brothers and not looking like the mailman's kid.

4 - speed. we're looking at a LOT more speed than factory binders are made to slow. we all recognize that all motors of similar displacement are not created equally, even within the class allowed mods. what is certain is that speeds will be a lot higher than similarly bodied IT cars. give them the mass in the braking system to cope with that.

downsides:

some work. less IT-ish if you care about that. other than that...
