It seems like the bigger issue here is this: a 'dumb' suspension is a compromise for many requirements and conditions because it reacts the same way to any input. A skateboarder, like an active...

What exactly is wrong with friction here?
And you're trying to be funny when you say dampers are crutches, right?
Maybe. But when you have miserible time at competition, it would be nice to at least get recognition for what you achieve...
Our car was the lightest as of 2004 FSAE at 301 lbs.
I was dying to get a close look at the Western Australia car in Michigan, but I could never find it in the paddock between events. Did anyone get a chance to talk to them or hear their validation...
Lift? Why would you need one of those?

Our WR426 had a kick start, we fitted some italian electric-start kit. The quality of the kit was marginal. The 450 has electric start so that shouldn't be a problem.
Big G, you're not supposed to have a nervous breakdown until a month and a half before competition. Pull yourself together, man!
What do you mean by "bounce around?"
Here's another method we never got a chance to implement...

Ours was primarily a quick tuning tool.
Miliken has a set of 'quick' calcuations for wheel frequency and roll stiffness that are not as complicated. I forget the page but could probably find it...
We used a CAD solid modelling program combined with Mitchell suspension geometry software. The suspension software was simple, but made designing these sort of things easier.
Double shear is nice, but engineering is about compromise. There are no absolutes. Rumor has it a few teams mount their wheels in single shear ...
I was thinking of our previous 'big' cars. The '04 layout is different, but the engine does still come out the bottom.
Dropping the engine out the bottom is nice because it is easy to do on sawhorses. Plus, a chassis is heavy, but it's easier for a group of people to pick up. Just my personal preference.
I like that picture. Testing an inboard suspension chassis without loading it through the suspension is complete garbage, if you ask me.
I've heard that the '03 R6 was changed significantly, but I can't say for sure how different it is. I would triple check any CAD model you get...
I agree on going with steel if you're making it from sheetmetal and tubing. One thing I hate seeing, though, is uprights basically consisting of one tube in bending with a bearing support stuck in...
Good luck...
We did 3 weeks of practice/testing before competition, the actual competition, a full summer of autocrossing with 3-4 drivers per event plus some practice/goof-off sessions with some drivers who...
Even the best car can suffer from bad luck. If I remember they didn't finish the endurance in MI.
Probably suffered from "Pre-competition syndrome" which occurs only within two weeks of competition. It causes normally reliable components to take a giant shit for no reason whatsoever.
Either...
We run aluminum sheet. It tends to get beat up after a while since our cars have to be stored in a shitty gravel lot. And yes we make sure the chassis slaps out first - just be careful with engine...
It was sized for top speed, probably around 80 mph. The dramatic change in size from the previous year was due to the gearing of the WR 426. Due to lack of funds and testing problems, we did not...
