Thanks all for opinions.
911Rob,
I was going to call you but just found that you already have 2 P while I only have one, so maybe let me keep it
Guys,
I agree with you. I used to like the way it is but somehow, some other cars make me wonder if mine will look as nice as them if I...
Let see some more pics, ok? On the red car, let's ignore the front bumper. I can't take it that lowed.

What do you guys think?
Also, on the pic below, I am thinking to copying the design from the pic on the right. Make something similar but half circle (the opening) and put it on the corner of my fiberclass tail. Believe me, I can make it look nice. What I don't know is if it will look cheezy, and out of place. This idea is not for the look, but for more air comming into the engine bay. Do you think it will increase much air or too minimum?
