Rear Decklid, Grill and Spoiler Question
Has anyone here removed the rear Decklid, grill and spoiler(motor and all) and replaced it with some type of non-spoiler- including lid? I was thinking about this today and wondering if anyone had done that type of backdating before. I haven't ever seen it. I searched for a while on the Internet and here and couldn't find anything.
Please don't shoot me. I am just curious.

If you pull the decklid, grill and motor. I'd like to be first in line if you are selling. I am going the opposite direction and taking off a Turbo S tail. It was either that or add the turbo S front spoiler.
My car has the wiring harness in place and mount for motor on the decklid arm. Also the original sticker lists the split grill as being on the car at the time of purchase.

I've purchased a deck lid off a wreck and am working on what I consider to be a more pleasing treatment of the rear deck. It's not ready for prime time yet, but I think it will look much smoother than the scab of plastic that sits on the back of my car now....Before everybody starts screaming about down force, that's not an issue for me....I'm a street guy, not a track guy.....Stay tuned.

Me too, I have a complete deck lid (with the split grille option) waiting for installation on my C2 or C4S. IMHO the 993 looks much nicer without the rear spoiler engaged, especially on the WB cars....then again the New England weather gods are easy on the high temperatures and I'm slower than a Floridian at Limerock and don't really need that performance edge

Actually, IIRC (and I'm sure if I don't, I'll be corrected! :-) ... the small rear spoilers are designed more to eliminate yaw (rotation) than lift at speed, it's the front intakes and splitters that neutralize most of the lift .. BUT the speed activated spoiler on the 964/993's are also letting a huge amount of air in to the engine compartment to cool the motor. The flexible airdam stops the air from exiting and forces it over the motor at speed.
See above ... there's more to it than meets the eye.

No, it was reduction of lift, and there was published documentation starting with the ducktail that showed how effective that small spoiler surface was. Not to say there isn't a yaw component meshed in, but the 911 profile is very similar to an airfoil and with high speeds will see lower air pressure up top.

Over a period of almost ten weeks in ambient temperature conditions ranging from the mid-80s to almost 100 degrees and highway drives ranging from 10 to 150 miles, the difference between conditions 1, 2 and 3 above were negligible.
Worst case, it doesn't work out and I'm out a few hundred bucks for parts and such. I'll just put the stock lid back on a plug it back up.
That said, this isn't about proving anything to anyone. I cut my teeth on street rods in the 60s and just think it would be fun to take a shot at creating a look that is a little different. I've found a local rod shop that's interested in working on the project so we'll see what happens.
