Hey Marty,
your plan sounds good, although I would be unsure about the benefit from a spoiler wing. The weight savings sound nice also.
Regarding the LEDs, I will only replace the bulbs. Not the complete housings. The Halo taillight look awesome though.
The Wideband O2 is an additional sensor in the exhaust that I use to tune the fuel maps in the ECU. I use EFILive for tuning the car. I still have and need the stock 4 narrowband O2s. The Wideband is in only temporarily to tune the engine.
I'm monitoring the treadwear on my tires very closely and could not find any uneven wear yet. When I do a burnout I can see the full width of rubber on the street even with 40psi.
I bought the solar panels from ebay. They come with a cigarette lighter jack that I plugged into the console compartment. I bought them to fight the battery drain during the daytime when the car stays in outside sun.

Which seats are you going with? Corbeau A4s? I have thought about this also.

Hey Alex

My plans right now for the C5 are to add aerodynamic tweeks first..
vortex gen. carbon fiber wing, venturi and underbody smooth panels

Marty

What? We haven't sufficiently proven the vgs and wing to not be in the interests of lower drag?

Frank, I agree on the VGs but I never questioned those.
Regarding the wing, I'm still not convinced that this specific Corvette wing will gain something. I might as well be totally wrong with my assumption.

Alex - He was saying that neither the VG's nor the wing will help with aero on that car. The VG's actually increase drag by an increase in Cd and A, but help overall because of the function they perform. They need to be employed on a much smaller scale to help out on a car, though, especially considering the Corvette already has a nearly ideal rear slope.

I was remiss in not quoting Marty- that's who I was really speaking to as he indicated today that vgs and wing were still in the current plans.

I guess i got confused a little bit from the last posts.
To sum it up - Marty, don't do the VGs and wing and spend your money on other things!?
Please correct me if I got it wrong again.

Correct, Sir.

The VG's and wing are going to be a styling cue, not support clean aero. I'll have to look it up, but I believe the car actually makes downforce as it currently appears, without the addition of wings and fancy aero stuff.

(besides some applications of the salt flat wing and the herod wing)

arent basically all wings detrimental to mpg

Any body extension can be considered detrimental unless it's benefit is larger than it's cost (not money cost, aero cost).

Each extension you add also adds skin drag and could create higher dynamic rolling resistance, etc... You have to ensure that the benefit of the mod will outweigh it's penalties.
