Cool...thats a real nice setup. I realy like the morot/bearing mount assembly...looks real streamlined....and the two seed, oh, good lord! =) How much JPY does it retail for?
The only thing that I can come up with that kit you showed and the other center deck focusing aftermarket kits out there is there there is no provision for torsional flex(if your grab both bumpers with each hand and twisted in opposing directions) The main reason I like the Xtreme chassis is that it effectively set's itself up in a tub style layout but without the tub. The lay out prevents both flex from front to back and side to side, making it super stiff.
Maybe it's overkill to have a chassis that stiff, but in the racing world....there is no such thing as overkill
