Looks great actually, much improved, but lots of essential low grip options left out, eg, ball diff, allow upper gearbox tops/shock mount, etc. I guess the choice is there to add those in if you need, along with all the other blingy bits schumacher offer.
Also its back to saddles, so you still need a shorty lipo conversion.
The old body should fit, barring the modification/fudge that you needed to do with hot spoons to clear the spur with a low grip chassis.
The rear end wishbone hangers are a good choice, far better now than the old method:
I'm sure it will do really well, and upgraders may find the cost of the new bits so close to a new kit that they may as well get the new kit.
