i am waiting for my rear spoiler to arrive so that i can get it, the front splitter, side rockers, and the rear bumper painted le mans blue. and i am seriously thinking about having my rear diffuser painted le mans blue to get rid of the black/grey that's on there now.https://www.vicrez.com/vicrez-centa-...RoCy74QAvD_BwE
I don't think it's the angle of the pictures making this look ugly!!






Good God, not no, but hell No.
Barring the looks it self begin off putting to begin with (screams ricer), it will have the same problem as the C7 Z06 rear spoiler with it center section raise up, being so much drag, you may well drag a parachute behind you.
Lets start off with the problem of the C6, and it's the flat back that cause a lot of air disturbance of the air leaving the car.
skip to 1:18
So unlike a R8 that the air leaving the car is blended back together to help pull the back end down that way, the C6 flat back end/lack of rear lower valance flow bending the air back together leaving the car, it cause a build up of pressure wave all the way back to the front of the car.
Now add in a higher lip rear spoiler for say more rear down force. but even more rear end flow disturbance, all you have done is just created more drag against the car/higher pressure wave all the way back up the front of the car. Simply, to gain more down force and not increase drab, it's really more about using the air that is coming down from under the car, to assist pull the rear end down; not a huge air block wall that will just created more air drag than it's worth.
And lets take it a step farther, if you are going to increase the down force on the back end, you need to increase the down force on the front end to balance the cars down force so it handles correctly as speeds a well.
