Now that I have molds for my bumpers etc, I'm looking at getting some more subtle aero happening. I'm doing up a splitter for the front and now designing a rear diffuser, plans are basically just to copy the APR guys stuff for the evo's and STi's and the like and make something similar for the 75.

Examples




Now I know a lot of the racing guys just cut out the rear bumper to stop it acting like a parachute but this is destined for my Evo rear bumper so I'm being a bit more vein here and looking to get some more downforce in the process. I'm not sure if I'll need some upward angle toward the windscreen to stop the parachute effect or not.

Any ideas or comments very welcome, I'm open to criticism.
