Just completed my prep for NASA GTS 3 but now I need a wing I need some suggestions.

Try this link. Has a lot of great pics.

EDIT: upon looking again, not too much there i guess.

Here's another good one.

Does the aero advantage in corners outweigh the increased drag on straights? Several people I have spoken to with wings all said their straight line top speeds were reduced by approximately 5 mph. The advantages in the turns were difficult to quantify. Just wondering how that translates into lap times.

Has anyone here done testing with and without a wing?

I just bought this wing off a CUP world challenge car. It’s a Crawford wing that has a airfoil design to minimize drag and maximize downforce. I’m going to used the GT3 uprights and make some brackets to fit off the back of the car.

wings work! remember to get downforce for front as well.

I've drove 2 identical 996 C2's with aprox same milage, same tires etc, only difference was GT3 optiks meaning front, skirts, wing etc all set to max, the difference in stability at highspeed turns/hilltops etc was huge.

Yes wings work.

However you can't just put one on and walk away. It takes planning to determine the right wing and how to set it. Then after that you need to drive to take advantage of that downforce. The place you will see it most is in high speed corners and you will need to push the car fast there. If not you may only see a change in top speed.

I picked up an APR wing...the DTM style a lot of the series run in Europe...it's a small enough wing that you don't get a bad straight line penalty, but it seats the car nicely in the rear...and on slow turns where i want to throttle steer it the rear end is still loose enough. I really did get lucky with it...I just wanted a wing for $100 bucks and to loose the wieght of that rubber spoiler...actually if anyone wants to buy the original spoiler It's in nice shape...50 bucks takes it.

got pics?

Well I have no doubt wings work to improve grip. I guess my question relates more to the net result in terms of lap times on a car with modest horsepower. The increased aero drag on a 400 hp car will have less effect on the car's straight line speed than on a car with 200 hp, but given similar cornering speeds the wing will produce the same downforce. It seems to me that the net positive effect of the wing would be much less on a 200 hp car than on a higher hp car.

I would be curious to see lap time comparisons on a relatively stock 951 (<250 hp) both with and without a wing. I'm not saying the wing wouldn't reduce lap times, I'm saying I don't know, and would be interested to see the results.

i like this wing of larts car

Localy we have racer who ran a Nissan 240 SX turbo. Car put out 250-260ish wheel hp and he said aero down force made a big difference. He also put out some insane lap times. Most figured he had 400 hp, but he did not. Just a very well developed chassis and took advantage of aero.

Now most of this was done at PIR where we the oval section of the NASCAR track. Most folks enter the oval at 80-90 mph and constant throttle the way around. They are grip limited. Adding aero downforce here yields major gains as the corner is long and takes about 7-8 seconds to complete. So using areo to gain you 10 mph is huge. If you have slow corners and long straights it may hurt you more than anything. However if you have lots of 70+ mph corners or just one really long one it can be a major help.

The only time it may hurt is you begin to flat foot it around these corners. Then you have too much grip for the hp and the aero is causing drag. For our 944 spec cars at PIR we are already flat out that oval banking so for us a wing will just slow us down.

I have a buddy that had a GT4 911 with 184 rwhp. He felt adding aero - GT3 style wing and front splitter made the single biggest impact on lap times of any mod he did. His lap time improvement was in seconds not tenths of seconds. He did some fooling with attack angles to find the happy medium between drag and downforce.

fastmover

That is exactly right, if you put a wing on the car you have to tune/adjust the wing angle of attack. too much attack and it will cause uneeded drag and slow you down. Get the right angle and your good to go.

Here is a adjustible dual wing.

Good thread. Be nice to have something available like a GT3 car that isn't huge and is still ok on the street. I mean the model 'GT2' or 'GT2', not the division. I guess the closest we have is the adj. 968 one?
