front diffuser/rear and aerodynamics

[crzsteveo]

has anyone created their own front diffusers or splitters for the front or rear for their s-chassis?

ive researched a little on the aerodynamics of it and how downforce can affect a car.

Im currently trying to think of ideas for a time attack look for my car. s13 hatch.

im mainly thinking of making something for the chuki bumper I have.

my car isn't super low nor high. just an even stance.

I was wondering if anyone on here can give me some more insight on splitters and diffusers specific to a s-chassis, if it matters.
