front bumper canrad's angle
hi guys.. i just bought Dev sport canrads for my Amuse R1 bumper to add some extra front end grip. at what angle should the canrads be set to be efficient in circuit use? i mainly track my car in Bahrain's international circuit which feature some long straights so i dont want the canrads to generate too much drag. any input is appreciated .. thanks =)

Canard is the spelling you're looking for.

password jdm recommend to install their street version canrads at 22.5 degrees and claim they'd generate around 42pounds of downforce on each side.. do u think i should do the same with these?

The primary function of a canard on a car is not really to create downforce by itself, but to create vortexes along the side of the car that help keep the airflows under and over the car separate from each other, increasing the efficiency of a flat-bottomed, skirted undertray. Used as "wings," canards are extremely inefficient, but since you probably don't have any kind of ground effects happening, you won't get the intended vortex benefit, so you might as well run them at a relatively low angle of attack to get a little "wing" type downforce. Probably 15 degrees is what you'll want.

Good looking car.

Are you racing the car pictured in a class where 10ths of a second are going to be the difference between winning and losing something of important? If not, my recommendation is to leave that very attractive, pretty unmolested S2000 alone.

IMHO, I'd start with a swan neck rear wing. Less drag and works more independent of yaw angle (in a turn there is always a yaw angle). Then the splitter, which will be hard to get right without a good CFD or instrumented testing (there is a reason F1 cars run those big pressure measurement arrays in practice). Then venting the hood and the front fenders. There is a lot of air flowing through the radiator and it needs to leave without creating pressure under the hood. Most (all?) current LMP cars vent their fenders on top (Evasive has a fender that vents on top).
Is there someone reading this who has a measurable improvement in lap times or added more angle of attack to a rear wing to balance the car after adding canards?
