You won't go wrong with Motonica. But there is plenty of choice, at least here.
Top level chassis are also WRC (

WRC in particular was kind of a earthquake when came out few years ago! It was something like half a second faster of everything else...! They really raised the bar, with a car having much more traction than everybody had.
Talking about rear toe in, when it was finally liberalized we saw the birth of systems to adopt 4WD rear hub carriers on "old" chassis born with no toe.

With rear toe in everybody is able to handle at least a Nova Race or max Power XL7 or Piccos or whatever fast. To deal with 9 ports Novas is a bit more tricky since they have a rather aggressive power delivery.
