3. No, and they are pretty ugly on the clean S front nose
2. No, I don't have them
1. Some thoughts,
Canards can be significantly functional as part of a overall aero package, but they are much more of a device for tuning balance and flow shaping than they are significant as stand alone generators of force. They can have a dramatic effect on the airflow down the side of the car and can work with barge boards to stop air from curling under the side of the car and reducing the effectiveness of a rear diffuser. Also, they can seperate flow ahead of the wheel wells and reduce drag losses there. On the negative, they can reduce effectiveness of front splitters.
Canards are not a preferred method to generate downforce because they create a very turbulent and often seperated flow at the front of car and you pay big drag penalties for that flow covering the rest of the car.
If I were wanting to improve the aero of a street car for track work, I would work in this order
Wing - works fairly self contained to generate downforce
Splitter - cuts down flow under the car to reduce front end lift and under body turbulence (drag)
Flat floor, barge boards, diffuser - reduces drag and creates massive downforce from boundry layer manipulation and huge surface area
Canards, vortex generators, gurney flaps, etc - work to shape flow towards or away from specific parts of the aero package
SO... in most cases I think people buy cannards because J's racing sells them and they want to drive a race car.
BUT if you are willing to go all out and do your homework (either with yarn taped to the side and a camera or CFD) it could get you a second here or there.

(off topic a little) What's a modest wing out there that doesn't look too ricey and still has good function? I've always been iffy about a wing bc although I love function, I don't want to sacrifice looks being my daily too... I do race a lot though lol

good ideas, but never liked the mugen wing (IMO). no molded canards like the cr lip either since i have the mugen lip..
if i did get aftermarket canards- i would definitely paint them the color of the car to avoid rice, but it may make it look worse anyway- or better? dunno..
the canards by jdm seem to perform the same way as the cr lip.
how is the ride at high straight speeds with that cr lip anyway, psychoasn?

Since BrockB is drag racing he should look more to NHRA than JDM. I'd try changing the rake of the car and try different tire combos (between front and rear). Ditto on the alignment comment.
