I am sure the super chassis is thicker and has more cutouts just like all of HPI's past super chassis.
You can see it in pics on the HPI site.
There are additional cutouts on the top side of the chassis also, which you can't see in the picture. It's much stiffer than the stock chassis and about 22g lighter. 7075S aluminum.
Another thing to lose weight is to use 5 700mAh or 800mAh Ni-MH AAA batteries instead of a standard receiver pack. I believe this saves you about 40g. Stack them 3 on the bottom and 2 on the top, solder wire and plugs to it and Goop it or tape it to the receiver tray.
Using a personal transponder will also save you several more grams, I'm not sure of the exact weight difference however.
Hara used the AAA pack and personal to save some weight on his car.
<joke>You can also remove every other fin on your engine head, acid-dip your body and tuned pipe/header, and use a see-through paint job to lose more weight</joke>
