Aerodynamics is something that has always intrigued me and I'm wondering if anyone has had experience with aerodynamic alterations on a sedan based car.
The car in question is a Fuego, which would appear quite well designed from an 'upper body' wind resistance perspective, but rather lacking in air management and lift.
I was thinking of building a front splitter/undertray that would extend out a few inches from the lower bumper and go back to the front cross member. My main aims are to improve air flow through the engine bay and cut air flow under the car and also produce some downforce, more so at the rear, where the shape of the car seems quite condusive to creating lift.
I was also going to try and put slotted rubber flaps over the large holes for the steering arms and drive shafts and also seal the gaps between upper and lower chassis rails to prevent high pressure air from the front wheel wells getting under the car and into the engine bay.
I may try and smooth the under car flow a bit, especially around the rear suspension and bumper bar.
Not sure what to do with the rear end for downforce as the only spoiler I've even seen fitted to a Fuego was a cosmetic rubber one that look pretty average and do nothing.
What have people tried and what were the results? Are there substantial gains to be made? What did you use for construction.
For the under car covers I was thinking of just using corflute and maybe a foam core composite panel for the splitter (its about 10mm thick but weighs nothing and is strong and stiff - its used on yachts and i may be able to get some off cuts for nix)
