Not that much to choose between them, and depends what you're lowering - a VTS is approx 30mm lower than all the rest anyway so you need to bear that in mind.
You need to look for offset or et of 15-20, PCD 108 4 bolts and bore of 65.5, I think. The larger the wheel you use, the lower the profile has to be. Normal is 195.55.15 , if you go to a 16" , I think you can drop to a 50 profile. This is often cheaper to buy tyres for, strangely enough.
The lower you go and the lower profile tyre you fit will harden the ride and may become uncomfortable - handling will feel more direct and you may notice the tendency to tramline.
