Aero mods?
Are there any proven aerodynamic improvements available?
Not looking for mirror removal and racer-taping seams..
Things like:
Chin spoilers
Splitters
Belly Pans
Diffusers
If so who makes them and what are the improvements?

As far as I know chevrolet really did their homework getting the c4 to be slippery in stock configuration. To be honest i would think you would have to be really moving to get any benefit from any sort of chin spoiler or splitter.

looks to me like the first step is to vent air and pressure out from under the hood. There is an interesting thread on ax/rr that I hijacked (just a little) to discuss C4s. Somebody reported measuring a 2 psi pressure diff above and below the hood. A pair of vents over the 2 & 3 exh primary looks like a good spot to vent pressure as well as heat. There is a good Cad aero map of a C4 on that thread as well.

This thread has a lot of good info about aerodynamics (specifically for a diffuser build)

Been reading tons of threads about the rear diffuser on c4s.But i dont see any place that sells the aluminum ones.A few on here have built them and they look killer.My hold-up would be welding the aluminum,plenty of build info on here though..good luck

I wonder if the Shinoda Mears kits worked. I remember the threads on IRT Shinoda Mears were mostly on how no one could find one.

IMO They look great and if they work as well as they looked they be the ticket.
Especially with a working diffuser/partial belly pan

I can tell you that from years of seeing people put all kinds of "aero" parts on their cars.... 90% don't do anyhthing but make it look better... but some do the opposite.
If you want aero parts that actually work, talk to guys that take their vettes to the track because those parts will usually work in some way. The only real functional chin spoiler I've seen was one on a ZR1 that had brake cooling ducts.

Thanks Ziggy, your experience confirms mine (90+% of things that are supposed to enhance performance don't)
However, it seems like the track guys priorities are on things other than drag reduction.

You have to be going seriously fast to even have them take effect if any.
The spoiler GM put on there does a decent job at keeping air from going under the car...hood etc. Like the cowl induction. It works but to really see a gain Id bet youd need to be doing 100 or better.
