these are good quality springs. the max lift on them is .700, I plan on running .470 or so max figuring in the 1.65 rockers

i dunno... that spread on the spring lift capabilities might actually kill a little bit of performance...... do they make the same springs with lower lift ratings.... if you could get it in like a .500 that would be a lot closer

it's looking like that's it, for performance springs anyway

Spring harmonics can do weird things, as can resonant frequencies.
