99 spec wing for autocross
 

so I have a friend selling his 99 spec wing he said he'd givem e a good price on it ..

BUT i'm on the back foot . Firstly I like the FD's WINGLESS lines . BUt I'm also a firm believer in function >form .

my car is a bit loose at autocross. ( meaning oversteery) specially on corner entry.

Wing wasnt even in my scope if it wasnt for hte price he's giving it to me at ..


But after a bit of research .. How much downforce will this wing really produce at auto-x speeds ?

This is also a street car so .. I thought the 99 spec might be a good halfway point . But my question after all this long winded babbling is will it be usefull at the slower auto-x speeds? or just be there for looks ?? :scratch:

a little info on the wing from '99 FD3S

The RX7 is very unique because nowadays there are many kinds of traction control and vsc and the RX7 is the only real sports car that doesn't use any electronic device. The Mazda rotary engine is still the only unique engine in the sports car market. This was a big advantage years ago but now other engines have caught up and the rotary's light weight and power advantage is getting reduced. The new rear wing was made because the RX7 is aerodynamically critical due to its light weight. the wing is adjustable to create down force and also gives a spoiling effect to reduce drag. There are 4 positions 1, 5, 10 and 14.5 degrees.
c/l value 1deg =0. 14.5 deg = -0.075

It won't help at autocross speeds

You need a real (big) wing to be of use at autox speeds.

at 30 mph according to math, 99 spec wing can put down 47lbs of downforce .

ok more like 10 lbs of down force forgot a decimal =P
