Agreed the front damper oil doesn't need to be too high. I tried 70wt and 3 hole pistons before, much to stiff. I ended up with 40 3 hole which seems pretty good front and rear. The rear springs I've found just need to be 1 or 2 levels of stiffness lighter than the front.
The shocks look pretty good! When you do end up getting the sway bar on, you'll need some collars as they don't include them in the kit. Secondly the rear sway doesn't need to be too stiff (use the lightest or none) as it makes the rear end slide out quite very easily if it is.
Happy to see the Xv-01 getting upgrades!
