Optimum suspension setup fopr 15"s

[taracor]

So I've been looking at wheels and suspension a lot lately, and want to figure out the best set up to get for the money. In terms of wheels, I am debating between 195/55/15 or 205/50/15. My reasoning is, get the car as light as possible to get the best performance, (in which case the 195/55/15 should be the lightest, correct?) but on the other hand, with the 205/50/15 I am getting quite a bit more contact with the road. Which is going to be more beneficial?

In terms of suspension, as much as I want some Tein Basics, I think I will be going with springs and shocks for the time being. I'm debating between Tenabe DF210's or TRD's. I'm trying my best to avoid rubbing, so that's why I'm not just going for the DF210's. Any advice on those? (Or maybe I should just save for the basics?)

This is mainly for road use, but a little bit of track, by the way. Thanks!
