Cool, it appears we will just be able to buy the chassis and other various parts to upgrade currect rb6's to 6.6's. Maybe 200 in parts im guessing depending on what you want.

The rear bulkhead is a little different, look where the shock tower would mount.

The rear suspension mounts have changed too.

Something changed in the steering cranks, their words not mine.

I am still trying to figure out how they can state the chassis is 13mm longer and the wheelbase is the same. Maybe someone else knows because it doesn't look like the location of the suspension arms changed.

Unless they changed them, they are the same.

It shouldn't matter. Whichever side is easier for you to adjust it from.
