Those rims are just the GRP standard offset rims.
There is no way they would piss off the 1000's of there users that already have 1/2 offsets
The only difference in the arms should be the 3.5mm hole for the larger hinge pin in the rear and the smaller holes in the front to stop the screws backing out so easy like the 8 2.0
The steering turnbuckle looks to be longet so it could be a longer arm
But the chassis is 14mm longer so i would guess that the car will be wider to combat the length
Im not a fan of the new body. It looks like a SUV

but i guess it has the same low design like the new buggy to keep engine temps down
