you got a good point there, should of taken all that into consideration... my bad lol (although 1st time was very warm and bone dry...2nd time was very slippery..but yeah i get you point
)
but generally you know yourself, if you notice any change in your car when driving it hard, and i would certainly say there is a small difference
also i think when the bumper is cut out it looks awesome, so either way you get a good look and a 'non-parachuted' bumper lol
