I think the Swifts probably would be. That was my original plan, and in hindsight perhaps I should have. That said I love being able to tune the damping and tweak the ride height as I see fit. It would be hard to lose that ability.
I've looked at countless pics of Zed's with Swifts and there seems to be a variety of different ride heights, even though all the same springs. Some haven't settled I'm sure, and remember someone (think it was cooltoy - who really knows his stuff) mention that once Swifts settle you can add another .2 drop on to the numbers.
Those wheels bring the hotness!
