well, I put it this way. You don't have much choice. I've seen numerous DSS stage 5's break with 400whp (be it on a mustang)...regardless, its far from 1000 that they claim.

The other choice you have is 2k per set of axles

Just FYI, we subies blow up lots more rear CV's than fronts...Mitch is still shredding his stockers at 800whp as we've discussed real options for putting power to the ground. I think he's saving up $4k.
