K i am trying to get either 19's or 20's rim with volk racing GT-C i was just wondering if they will slows down my car speed. How much slower my car would be .
whats the good side and bad side if i change ?

 

The farther away you put a given amount of weight from the axis, the harder it is for you G to accelerate. The top speed won't change unless your tire diameter changes.

So if you put a 19" wheel on, but a tire that ends up being the same diameter as stock, your speed hasn't changed but you will accelerate slower and brake slower.

i was thinking of getting 19inch gt-c's also until i realized that id be losing performance. I'm now thinking of 18" gt-c's and possibly a set of springs and camber arms to fill up the wheel well. I may stick to the stock pilot sports tho and just get those taken off my stock wheels and wrap my 18" gt-cs with them.
