It's a very difficult topic. As each cars specific suspension geometries affects the outcomes as well. Then you have to consider how lowering the car has changed the angles/geometries etc.

Don't want to get into an argument, but if you look at tire sizes on sports cars from companies who spend a ton of time on suspension technology(not as wide), compared to companies who don't(much wider), they use drastically different tire sizes for relatively similar results. Which leans toward wider helps generally speaking as a simple way of increasing grip.
