Well guy's i'm working on a set of canards for the DC5. these will be a perfect fit for the 02-04 stock bumper. They will be made out of 1/4" thick carbon fiber and will include metal L brackets. They will be a way cheaper alternative than the J's Racing or any of the other brands out there. here's a pic of what i have planned, let me know who is interested and i'll see how many sets i can make. They extend from the fog light cutouts to the edge of the fender. Price will probably be around $75.









at 60mph:
downforce achieved at 40 degrees: 13.461 N
downforce achieved at 45 degrees: 15.140 N

at 90mph:
downforce achieved at 40 degrees: 30.286 N
downforce achieved at 45 degrees: 34.064 N

at 100mph:
downforce achieved at 40 degrees: 37.357 N
downforce achieved at 45 degrees: 42.016 N

at 120mph:
downforce achieved at 40 degrees: 53.842 N
downforce achieved at 45 degrees: 60.558 N

I'de be interested in seeing a final product. I'de like to see a set on your bumper before I make a decision, but the "prototype" looks kind of promising. How much we looking at, price range wise?

 

Good luck, pics of product when finished...

Oh yeah, Emachines suck.

 

haha yeah emachines do suck. you're lucky at probably around $100+ less than the J's and others, so probably around $75. price might be raised or lowered from the interest i receive or how costly the material is.

 

$75-100 for a set of 2? Or 4?

1 set = 2 canards.

 

I've been using eMachines with no problem, $299 special at Best Buy

Anyway, please let me know on the status of the canyards, I might be interested

 

for those of you who are concerned about downforce at certain speeds, i have updated the first post with some calculations.

 

I'm not trying to be a dick but I have always questioned the effectiveness of canards. Though the force figures you gave may seem impressive at first, when compared to the force causes by gravity, they are almost nothing:

Force due to gravity on the front end of RSX (assuming its mass is 680kg): 6670.8 N

The downward force due to the canard is only 0.908% of the force due to gravity at 120 mph, 45 degrees. Gravity is 495 times more effective than the canard at 60 mph and 45 degrees.

I don't understand canards at all. The windshield is probably hundred fold better at forcing the car downward.

 

my take on canards is that they are not suppose to give you huge gains on the effect of downforce. most canards you see on cars are on race cars that have a bunch more aerodynamics than a normal car. that being said, canards are more of a tuning device rather than a gain giver.

 

So what do they actually do? Again, I'm just curious. Either way I'm sure they will sell.

 

depending on the shape, how large it is, etc, it will give significant downforce to help you through a corner. this comes at the price of more drag however.

Ahhh! I thought I just disproved that they don't! Also the 45 degree angle probably turns into a 35-40 degree and it bends laterally at high speeds because the bumper cover flexes. That's it, I offically hate canards.

I know you're putting a great deal of time and work into them, sorry for the harassment. Good luck on them.

 

downforce from the product isn't the only key thing that canards do. i know the downforce from the product is minimal, but the second thing they are designed for is to create vortices that travel along the side of the car. the vortices will act as a barrier and keep high-pressure air from entering the low-pressure underbody. Thus the low-pressure is maintained, and downforce is maximized. remember again that canards alone will not do much, but integrated with much more aerodynamic parts (splitter, underbody panel, rear diffuser, wing) they will help maintain aerodynamic balance.

bump

 

Bump for some good fab work on your part....Any shots of the Ft bumper from straight ahead?

 

when i mount them i'll take pics

 

in for final product

 

thanks guys if it wasn't raining right now they'd be on the car.
