I've put 1 crown wheel set in my fs2sp since I built the car. Just a matter of shimming it properly which sometimes means more / different shims to that supplied in the kit. I run a heavily boosted 6.5 or 5.5 with no issues.
Front towers are mostly due to over tightening the screws to the mount and not reversing the shock mounting screws as I advise.
Same story for mounts / gearbox cases, just snug up slightly longer cap head bokts with plastic washers under the heads of the screws.
Yes you had to pay attention when you built a zx5 but it wasn't fragile in itself like some other 4wd cars out there. That said I didn't seem to have the problems others had with predators either.
Either way the zx6 looks to have guarded against most of those issues.
