1520 is limited to 60k rpms, so whatever voltage doesnt put you over that is ( in principle ) fine- not exactly a daily driver kind of setup though, wouldnt really be ideal for offroading at ~70mph for example ( whicj is why speed runs are done onroad, not off ). I figure a lighter weight CF flux would be fine offroad with the MMM system & sensible speeds, then turn the original heavy weight version into the road missle with a single massive motor ( or dual motors if you really wanted to ) & HV esc. The heavier weight would be better for getting good traction & keeping the front end down- most guys have issues with lighter weight speed machines as the wind lifts the front end at higher speeds, so have to resort to front wings and such. Heavier weight would place a bit more load on the electronics, but if the motor/esc/lipos are upto task, then it shouldnt be an issue really ( just takes a little longer to reach max velocity ).
