I'll get one up soon, I am getting used to seeing the engine through the holes.
And when I'm at the track I dont worry, just do the best my car and I can.
the exhaust, rear bumper, and subwoofer removal from my car made a real difference in the rear.

 

Go with painted bumperetts very easy to install. If you just remove the bumperetts you will have 2 big holes and also the metal mounting tabs sticking out. I think the only way to remove tabs is to remove the rear bumper support. A body shop will charge an arm and leg to fill and paint holes. You can also get the euro bumper, but it will probably cost a bit.

 

some ferrari like mesh should look cool and help the ngine cool down... some one should try this... im thinking the license plates could bolt up to the mesh...

 

Markski did what you're looking for... and he recently made another thread about it.

No bumperettes, just a clean license plate "plane."
