Changed to 300# adjusted and the ride is very good, I have not hit any big dips at hiway speeds(75+) so I am not sure I will like them!
I am thinking maybe 350 or 375# may do the trick and run through the adjustments again to fine tune.

I plan on using the QA-1 coilover conversion kit. It uses an 8" tall spring, so I wonder if that makes a difference? It seems like the 375# would be the best since I have an LS1 and no A/C.
