I would say a lighter chassis would have little to no effect on the shocks recovery from a bump if the shock is "Precisely" re-valved and re-sprung for the weight. Extreme weight changes could not be properly overcome though.

The problem area would be that the weight under the shock(unsprung) hadn't changed to effect the lighter packages recovery from an impact. (as has been stated)

If you changed the lighter chassis's shock, as well as the unsprung weight equally then the only remaining variable would be the shocks O-ring/piston fit friction and pivot points friction to overcome the lighter package.


I think this is why a lightened chassis can cause handling issues, many of these variables can't be overcome with BIG weight reduction.

But $125 screw sets are still cool for those with plenty of disposable income.
