I do not have prices yet but I figure it will follow in about a month after the car is released. I'm not sure what it will cost as the S will have alot of different stuff. even the chassis changed so it may turn out to be cost prohibitive. I'll let you as soon as I know.
The changes look fairly simple but in actuality its a pretty radical tear up to the car. Probably the most radical change since the car was origionally introduced. Its as radical a change as the Mtx3 to Mtx4 was. Alot of general stuff on the suspension is the same but everything else changed.
I wrote an article on setting up the UFO clutch I am posting on the g4S thread.
