Ok, so its a lot like wemmon's, his seems to work ok with #3 because it doesnt make anywhere close to the downforce of a good CSP spoilder. You could always build #4 and just drill I bunch of 1" holes in the air dam to bleed pressure and plug them up until the aero is balanced. The top picture on miataroadster's homepage shows two very good csp spoilers, notice how they wrap around and how they seal to the car (this is important for downforce and not being protested because if air flows under the spoiler it becomes a wing and is illegal).

And they have the 2 splitter options. The car in the back has #4 and has a lot of holes drilled in the air dam to bleed pressure to even out the aero balance, the front car is closer to #6 and supposedly wants more front downforce.

Isn't that a #4 on the back car because it has a splitter?

All good I was just making sure I understood Now wings are not allowed in CSP, but if you were running a wing how effective are they at autoX speeds?

At a steep angle, it is quite effective.

ok. Its a hack job. i know. Ill try getting to sealed more like bill's. Its nice to know its easily tuned by bleeding air. If I seal up the space between the trunk lid and spoiler and end up with too much rear bias then i can keep it the way it is until i get the front one made.

I swear it makes the car more comfortable on the freeway as well.
Also the blue miata above is now running something close to style 6

86 <> 96, even though they're both 10AE CSP cars (and so is bill's).

I see a lot of cars configured like #6 with a vertical face. Why are they not sloped to form a wedge shape? This would lower drag, would it not?

I believe in some cases its due to rules about being able to protrude from the front. And others its probably just for easy of fabrication?

In the autocross world, it's the former. CSP/DP cars can't have them protrude from the stock bodywork.

What size splitter rods does everyone use? I cant seem to tell if they are 8mm or 10mm. Is there an advantage to either?

10mm rods are worth ~0.5sec on a 2 minute course.

I run 12mm rods, but out of delrin rather than aluminum, thats why my car is so fast.

as small as you can get away with. rods create a lot of drag.

if they are in line with the direction of the car (less surface area), they will be fine.
