My peeve about tubbed cars is when they don't center the wheel in the wheel opening. If you are not going to extend the tub forward enough to centre the wheel then at least stretch the wheel opening so it looks centered. And bring the wheels out as far as you can, tucked up tight together just makes the car look like it could tip over from behind.
Style and Stance are everything with a car. If you don't have em, it just looks wrong.
