Showing off Formula SAE?

I guess that ya'll don't want to do Reveille again?

Come again?

Here's the car my buddy is the driver for. I almost went to school there, but didn't want to have to take all the math courses...

Sorry for the thread jack!

That's a pretty sexy car. I hope one day we get the resources to do a proper aero package.

do not apologize for awesome. that car is very sexy.

Those things look like great balls of fun to drive. Wish FSAE had a "lardass" category.

I know the "fast" way to do it is multi-element (4+) unsprung wings (like Maryland, Monash, etc) but damn I love the proportions of this car. Sure looks sexy.

the '03 or '04 cars nose was done as to resemble Reveille.

Not sure any of those cars still survive though...

Oh I seem to remember seeing that. Those cars still survive, and are owned by their respective project managers. We've only got '06, '09, and '11 in the shop right now. '07 was sold to A&M Qatar, '08 was cut up and turned into the front half of '10, and '10 burned up with a Lithium cell failed.

unsprung wings. Just the idea makes me tingly inside.

Mmmmmmmmmm.

The front sure wouldn't be fun to package, but totally worth it.

I've got a good way to make it work on the front end...

How does the design of that even work?

Here's a picture of Maryland's car that kind of shows how they did it.

It looks like they've got a 4-bar linkage arrangement locating the front wing, with rods connecting the wing to the front rockers. Here's a better picture with no body:

Is there a regulation wheel diameter and tire size for FSAE? Where do you get wheels and tires for them? What size do you use? Is it a special tire for autoX?

So long as it's over 8", you can run whatever you want. We actually tried to buy 8" tires, but Hoosier wouldn't make them for us, even though we said we'd order their minimum (around 50, I think). Personally, I'm glad, as the 10" wheels are enough fun to package.

We buy our wheels in pieces from Keizer (at least recently for the 10"), and the tires come from Hoosier.

We use a Hoosier 18x7x10 LC0, with is a soft bias-ply autocross compound, but there's no tire data for it in this size. So we don't know quite as much about how it's going to behave as we'd like, but we've got some experience with it and we're confident it's worth pursuing.

In reply to unevolved:

Thanks! I just checked out the Keiser site. Sure are some great looking wheels. Expensive I'll bet too.

They're not cheap, but you could certainly spend more if you tried. We just got a quote for barrels for 10x7s (6" inner barrel, 1" outer barrel) for $387 for all four corners.

The Keizers are cheap for what you get. They're good wheels and pretty light. Just make sure to check them for run-out.
