Very interesting topic. I was looking at Mugen or J's but with the shorter mounting brakets. Kevin's looks like it is about 8-10 inches high. I have seen some that are shorter (I think between 3-6 inches). Then the OEM ones that look like about 3 inches.

Seems to me the 3-6 inch custom wings would be in the best position to not warp the trunk and have pretty good airflow. I guess another question then is does the downforce that is created in an S2000 by the wing have a noticeable impact on driving?

Take Jackies car..., it has downfoce on the side diffusors, the front lip and the higher wing..., is that noticeable compared to stock? Is it functional or just good looking?

Hope I didn't just insult Jackie or any other Wing owners...,

 

All depends on how you have the car setup. If you have the wing set up with little wing angle, you might not get any aditional downforce till you hit 80/100 km/h. If you have the wing angled a lot, you will have noticable affect even at 40/50 km/h.

The OEM wing will have little to no effect for downforce. I can say this with coinfidence based on where the wing is located, the angle, and surface area of the wing. When traveling at say 100 km/h, the air will pass over the car very quickly. The air will flow over the car in a straight line, well relatively straight line. So the OEM wing will get very little, if any, of this high speed air.

Another option is to reduce vaccum. Try placing a a plate to the back of the trunk and have it mounted vertically. The moving car will have a cycyling air pocket behind the top and this verticle plate. The air that is travelling over the car will not get sucled into the lower pressure area, this reducing lift.

The Vette may feel like a high speed racer, but when it handles like a brick, you tend to take the turns at a lower rate of speed.

 

Yes it is.areodynamics is an important part of racing. The latest advances in F1 have been with undercarrage areodynamics. A 3 iinch wing will have little to no affect on down force, just like the stock AP2 wings. At the very minimum, you will need the 6 inch wing, but even then that is at the lower extreme. On the racing section, they had a good post with pictures and data from wind tunnel testing of the APR GT200 wing I think.

And remember, the additional downforce from the wings is not linear but exponential.

 

Thanks for the info SumAznGuy..., some very good stuff.

 

The Mugen wings come with short brackets. I think JL9000 has it on his car, look at the meet pictures.

40-50 km/h eh? Wow, I never would have thought it would have had an effect at such low speeds. I can see how understeer could be a massive problem. I think the vette handled badly cuz of the tires. They were extremely low pro and all seasons I think. Thanks for all the aerodynamic info though sumaznguy!

But can it outhandle our car if you tried to?
I heard the vette is a better handling car than ours and i've heard otherwise too.
Anyone here with experience? Do tell.

 

You need to be a little more specific. Perhaps I can be a little more specific. Each car has it's strengths and weaknesses. The S's weakness is lack of power. Put on a turbo or S/C and give it 350-400 hp's and good tires, and it can keep up with the 400 hp Vettes with good tires. If we were to talk about stock vs stock, the older Z06 Vettes and C5/C6 vettes are in a different class. Even the older C4 vettes with 275 hp's are faster in the straights and handle pretty well with their wider tires.

That being said, the S in race trim with the right go fast parts can be a high speed track car too. A set of KW3's, 17x9 or 10 wheels with 275 tires, right mix of areo parts, and a mugen HT, and force induction will be a fun track car for some of the faster tracks. If we were to talk about Mission raceway, there wouldn't be enough room to open up the legs on a forced induction S or a 400+ hp Vette. Mission is more about braking and grip.
