Im very happy with my KW V1's... The improvement over stock is huge!
There is a lot less body roll in the turns, the nose dive under braking is almost nonexistent and it's definitely planted on bumpy roads & turns now
I like how easy they are to adjust too... I first started out with a subtle drop, but I have since lowered the front and rear another 1/4" and even though I lowered it more from the original install, the ride quality hasn't changed at all.
Here are some pics of the drop before I lowered it a 1/4" more... There is much more adjustability left too, but I can't lower the rear anymore, because the tires already slightly rub if I have the kids in the back seat and I hit a big bump/dip in the road... I guess I should roll the fenders
