Spoilers for auto-x

[p0cket penguins]

I have a 2.5 inch splitter up front and im working on my zender wing with adjustable gurney flap... hopefully the flap at its highest position will help or at least even out the front splitter action... ill chime back in when i get it mounted... its currently primed.... then ill be testing it on the 25th of april at autocross.

I actually just ran the solo pro school and a local school and they all suggested running bigger events and I'll also be doing a few track days at VIR and Rockingham over the summer.

Its hard to explain what kind of spoiler I meant, I guess you could say its an extended IS lip that would be big enough to get some downforce but still look clean for street use

:)
If my plan works out then I'll have an e30 runnin at VIR this fall as well

^^^^^ I remember this car from Grand Tourismo 2! It was the most bad ass car on there.

Just buy one of these--

Find an old sprint car wing. they are fairly cheap when I've seen them by accident, and they'd be easy enough to cut and bend into an e30-friendly shape and size.

make some

Here's a good profile for autox:

[nrubenstein]

Ive installed one of the bimmerworld carbon race wings on an e46, and let me just start by saying its massive. Google a pic, ill wait.

Now that youve seen that, aerotuning on that starts at 80, so im afraid that your quest is destined for nothing other than maximum fail.

Wrong profile for autox. And although it works below 80, it's far too small for this application.

[nrubenstein]

I seriously doubt that any aero features you could add to the car will help at AutoX speeds. You'd gain more advantage by spending that money on sessions with a coach.

Aero has been proven helpful in autox. The wing profile is completely different, though. You have to use an extreme high drag/high downforce wing. It's a profile that's pretty pretty horrible over about 45-50mph, but it's a huge advantage below.

We're talking BIG, though. Really big.

I suspect that you have to go to wing that is position at or slightly above the roof line to achieve noticeable benefits. At least that is what you see on pro race cars that have had the benefit of wind tunnel testing.

This would be so fuh-raze on an auto-x car!

[2002maniac]

yeah alot like that but Im trying to either find one or mold one thats like that but one solid peice.

but overall thats what Im talking about maybe shorter. do you know how they made that?

That's my old car, it's just 3/16" or 1/4" ABS plastic cut to fit and held on with sheetmetal screws. It would be worthless for auto-x though. You will likely need a huge wing that sits at or above the roofline.

With that setup my car was planted and very neutral on 50+ mph turns, and it oversteered on slower turns.

Go down a few posts, something like that? I'd just make it out something.
