what increases front downforce more?
Canards or a new bumper?

depends on air dam and canards

street or race car? street: doesnt matter cause you prob wont be going fast enough for that amount of DF to matter.

Race: depends on how many and where the canards are but why not both?

you dont need to be going 200 for stability to matter. front end lift can happen even at 100. I had to put on a new front air dam on my Volvo 240 because stability over 90 was lousy, the nose kept wandering, and i was driving 100+ a lot. true the thing had the drag coefficient of a brick, but still

aerodynamics come into play on any car above roughly 65mph. The best way to increase front downforce is to reduce the amount of air traveling under the car by adding a deeper chin spoiler, to which you can affix a splitter. The splitter should be roughly twice as long as your ground clearance. In otherwords if you have 4" of ground clearance you should have approx. a splitter with an 8" chord.
Canards wont really do much until you clean up the rest of the airflow over and more importantly UNDER the car.
A great book referance is "Race Car aerodynamics" by Robert bentley publishing.

who ever delted my post, thats pretty weak. But, canards wont even do anything unless they are tuned right (im talking wind tunnel) if you do put them on, they will just add uneasy amount of drag, its just another ricer tool unless you use them right.

Aerodynamic "bodykits" that resist drag is just saying you dont produce enough power,,,,,,what im trying to say is you need to spend more money on your engine b4 you worry about downforce.

Any chin spoiler that effectively creates downforce will be way too low to drive on the street.

for the most part, but you can generate more stability at higher speeds by replacing the front air dam, without making it too low for street use. i live in Boston, the roads are terrible, but my air dam on the 240 was perfect, and it never even hit the pavement once

but no one has a clue if it added downforce though, even though your car gained stability, it may not have gained front downforce.

the front didnt lift as much, which would seem to indicate more downforce, but id say even if the actual downforce total wasnt changed it redistributed the airflow better, which is, after all, the whole point of aero bits
