Didn't know Dave would announce it this early but here it is!!? More specifics will be released at the end of this month but for now the one item I can confirm is a Nismo brand lightweight clutch for the Gen II X, the other items (gears, lockers, spools, axles, diffs) will have to wait on their very specifics as explained by Dave in his announcing post to be found here:
