I would be interested in one for sure, add me to the list. I already have the big bores, and I don't think there's too much changed on the suspension but I could be wrong. Does anything swap over? I need to find out. I know the 6 series plastics wear even better than the 5 series so it would be nice to swap out my plastic for 6 stuff later on.
5.5T sounds awesome too

The SHIFT body is really sleek, very good on a track.
Oh, and I'm very close to making my own chassis with milled cutouts for the battery trays, servo, motor, etc. It would be just like the setup I'm using now, but I might go with Mike's mount for easy mounting and less holes in the chassis. The Tekno mount is pretty light though, so maybe I can do some weighted tests between Mike's mount, the Tekno with plates and center diff plastic piece, and that Elite RC mount. That is, of course, if Mike doesn't make his 5.5T chassis.
