Well i currently have some work vsxx but there not aggressive enough 1" lip in the front and 2" in the back was thinking of buying bigger lips for the back and moving the 2" lips to the front what size do you guys suggest me to get for the back ??

Just measure how much you want to go wider. All you're doing is getting wider lips, so just measure from your current outer position to where you want them to sit. Then, get the size you need.

I made that thread because you're going to have completely different wheel specs after your lip change.

 

3" front and 4" rears

 

So, currently, these are the wheel specs, i cant seem to figure out from the links that you gave me can you help me out on how they would change if 2" lips are changed to the front and 4" lips are changed to the back.
Front: 19x8.5 +39
Rear: 19x9.5 +45


Also do you guys think it would look weird for havin 2" lips in the front and 4" lips in the rear.

 

Front:
19x8.5 +39 1" lip
19x9 +33 1.5" lip
19x9.5 +26 2" lip

Rear:
19x9.5 +45 2" lip
19x10 +39 2.5" lip
19x10.5 +33 3" lip
19x11 +26 3.5" lip
19x11.5 +20 4" lip

My assumption is you don't have another 2" (50.8mm) to go out (exterior position only since they're just the lips) in the rear without excessive poke or need of excessive camber.
