RKD in OKC

The under bumper wing added 10 mph to the top end of the 944 Turbo. I read this somewhere like road and track.

The boxster has a spoiler not a wing, it decreases lift as opposed to producing downforce. The Boxster and the Audi TT both become dangerously rear light without them. The boxster has a hazard light that warns not to drive over 70 mph if the spoiler does not deploy.

The 951 is not perfection nor something sacred that should never be modified. You could put wide white walls on your 951 and make it bounce at stop lights for all I care. But the 951 is a Porsche as much as any other 911, 356, etc and as its main attribute is its handling and feel at real speed. My "entry level sports car", a 951S, cost over $46000 new in 1988 and could blow the doors off most other Porsches in handling and/or outright speed on the track or the street. How does removing the spoilers move it towards supercar levels when it makes it slower and screws up the handing at speed? If different is what you want, go for it. But if you want to move it toward your perfection, and supercar status, I don't understand. But then again some think that wearing pants below one's butt so that one walks on the cuffs is cool looking, but I don't understand that either. Must be because I'm just an old fart.

Tms951, have you considered going with a bridge-type rear wing like found on late S2's, 951's, and 968's? I think that might be a better option than none at all, especially with a front lip on the car.


I'm not old and I don't understand that either. Recently there was a local news story here that made me laugh. A teen robbed a local convenience store, and while running from the police in his baggy pants, they fell down all the way and went to his ankles, tripping him up and causing him to fall and be caught by the police that were chasing him. The newsman was interviewing the arresting officer and he was laughing while explaining how he caught him. LOL.

The later 944's and the 968's with the hard wing is actually a 959-style

I am no physics major or anything so please correct me if I am wrong. But I never really thought it was a wing but instead a spoiler, as RKD suggested. The difference being a wing creates downforce but it has to be outside the turbulence created by the car and a spoiler smooths the flow of air comming off the back of the car. Helping to reuduce the turbulence that slows the car down. Same with the bottom spoiler.

That is why the bottom one was added to the 951. Like I said if I am wrong please educate me.

I have read that the front splitter adds downforce. The front splitter appeared on the lemans car which also had a revised rear wing or spoiler. The lemans car rear wing/spoiler was 2" longer and had a 2" taller lip. The purpose of the rear wing/spoiler, I would assume, was to add downforce to balance the added front splitter downforce. At Le Mans, due to the very high speeds, it is a very fine line to balance uplift (so the car remains earth bound) and not create drag (slow top speed).

A commercial airliner "takes-off" at 120 mph. I for one would not remove an aerodynamic piece or disturb the balance, from a vehicle that has the capability to go 155+ mph. My car tops out at 173 mph, and to quote Ferris Bueller "life moves pretty fast" at those speeds. Porsche spends a lot of time and money in the wind tunnel for good reason.

I suppose you could do what the Nascar boys do, and put a blow-out trap door in your roof to keep the car "shiny side up". The roof trap door is the main reason you no longer see "Flying Tauraus's" at Neckar races.

I miss those "Flying Tauraus's" by the way.

Plus I always thought the 924 had kind of a hump back look without it.

I do like the clean lines of the 924. I do not know the top speed of the 924, but when the 944 appeared with its body style and rear wing, the top speed was 132 mph. When the 951 came out with its top speed of 155, Porsche made several aero changes. Front bumper, flush windshield, front under tray, rear lower wing, extended lower side trim (skirts) at the running boards. Even smaller head light squirters (clever germans). All changes due to the increased top speed.

I think the 924 topped out at about 120mph, aerodynamic drag.

Well I have come to a decision. After reading responses here doing other research and talking to the guy who is going to do the work and has also done all the other body work on my car and the cage.

I am going to buy the 924 hatch and put an E46 M3 style lip on it. I am also going to have the rubber spoiler on the stock hatch shaped down smaller and covered with fiberglass, then a touring car style wing will be mounted on that, this is what I wanted from the beginning. The 924 hatch will be a nice clean look for street and show, it will cost me little all together to put this one together, and I will have a hatch when the other one is getting modified. I feel the M3 lip will break up the look a little and take away from the bubble look while keeping smooth.

As for the bottom, a section will be cut out and a rear diffuser will be put in place. It will be more of the race car/japanese look, and not like stock.

Thank you for your help and opinion.

sounds like you want something similar to the older 928s (pre-S4) like so:

MPD47

Touring car wing? No offense, that sounds absolutely horrible. ARP isnt making it for you are they?

Tms951

A little smaller than the old 928 but that is the right idea.

It is not a APR carbon fiber wing, with alu. stantions. It is fiber glass and will be painted. it will be cut down to 5-6" tall. It is the style of mid 90s touring car sedan wings. I think it will look very good on my car. Others will not agree and call it rice or just bad taste. It will be effective and flow with the rest of the body work. It will be there not as a fasion statement but to create down force.

This is the wing, it will be mounted to a one off 944 s2 style trim, the stantions will be 5-6" or lower the sides will hang down lower than the hatch 1-2".

MPD47

Ew.
