The only performance advantage is the Aluminum rear hubs, they have alot more adjustment for the ballstud.

The slipper pads and spring are better.

The CVA's are slightly different for improvement, where the bone goes into the outdrive cup, the bone has been made slightly thinner, this prevents the bone from putting pressure on the diff outdrive when the suspension is compressed. This should help diff gear life. B44 owners can see where the bone gets scratched by the outdrive cup.

The rest of the parts are mostly more conveinence items. Much cheaper to buy the whole the kit then to upgrade everything. And the B44 is discontinued anyway, the B44.1 is the only kit now.

The rest of the parts are basically running updates.

The v2 shocks are easier to build, but the rebuild kit costs more money. You also get the bleeder caps.

The motor mount really isn't much of a difference really. I didn't have any problems with the old mount. Get rid of the aluminum washers, and put some steel Losi ballstud washers in there and locktight the screws and the set screw.

If you run an undertray, the chassis really wont matter to you. You'll like the chassis if you use chassis protectant.

Thicker shock tower is nice, but I've run a cracked standard one for over three months before, so no big deal there.

You get blue aluminum screws for the transmission cases, rear anti-roll bar, lipo tray, the body, well to each his own.

I would have liked to see front shock shafts with 5-40 threads on the end to stop broken shafts.
