I ordered a new set of prg uca's and radflows with 650 lb springs. I had 750's on the old ones, with stock uca's, and noticed the front end could be a bit bouncy on the highway over the rough stuff. When I ordered my first ones I asked about spring rates and was told they were only offering the 750 lb springs, even with the stock front bumper, as they found the 650's had too much dive under braking. When I ordered the latest ones I was asked which spring rate I wanted and was a bit confused considering what I was told during my last order. I figured I'd go with the 750's again, but later changed my mind before the order was shipped and went with the 650's. Now I'm wondering if I made the right decision by going with the 650's. Who's running the 650's and what do you think of the ride quality?
