The V1's are great... I've had mine on for almost 5k miles now and I've been very happy with them, even as an everyday driver too! The car is so much more fun to drive and handles much better, even over bumpy roads, its still planted and not jarring at all.
Here is a picture of mine... my front is about in the middle of the adjustment, and I have the rear a little higher to keep my 275's from rubbing (fenders are not rolled yet) and I drove this way in the snow
