Actually, it looks like the straps alternate such that they can take a load in either rotational direction. They do sell these things as streetable replacement discs for EVO's and STI's.
I know what you mean about the withdrawal symptoms. Good luck everyone, and try to get some sleep before driving http://fsae.com/groupee_common/emoticons/icon_biggrin.gif
We used the Performance Electronics ECU this year and were happy with it. It is extremely easy to use with a Honda F4/F4i, pretty much a "wire-in".
A slight hiccup with the map being a little...
Here are a couple of random renderings of UIUC's car. These aren't what was used in the design report though.

Tire deflection with the 10 inch wheels was a little bit much for my taste: http://www.ec.uiuc.edu/soc/sae/formula/img/detroit02/008.jpg
I suppose you could make them work with lots of static...
We have one sitting around in storage, it weighs around 10lbs more than a 600cc F4 does. Its also not any easier to package for IMHO, as the V sits front-rear. The plugs are hard to get here in the...
Also, we've never bothered to set the timing to the degree because we never had a timing light that would work with coil-over ignition. We ended up making one that fires off of the TTL signal from...
The only reason you need it to be accurate to the degree is if you care about your timing values being spot on with that you're typing in. These engines are all a one-off intake-exhaust design, and...
Are you running a batch fire system or a sequential system?
The MoTec has a special mode that holds the timing advance constant for setting the CrIP. Of course, I don't remember where thats at...
Here's the final, longer promo video, including footage from the event with UMC and UMR:

We also used spherical bearings in Fox Vanilla RCs last year, that worked out pretty well. I believe we even found bearings in the correct size to just press in, but I don't remember the size or the...
We ran 10 inch wheels with Goodyear tires and 13 inch wheels with Hoosier tires back-to-back one day last summer on the 2002 car. The suspension had been tuned for the 10 inch wheel and tire...
Back to the weak clutch subject . . .
We've been running full face kevlar wet clutches in our CBR F4 with stiffer springs for the last two years. We roasted a stock clutch pretty badly during the...
Rantoul is a small town about 20 minutes north of Champaign-Urbana. The course is a parking lot of an old WW II military airbase.
It is about 3.5 hours away from St. Louis, maybe a little less....
We've used the Motec M4 for 3 years now without any problems. We were going to run our own ECU that emulates the Motec wiring-wise, but unfortunately some of the internal ECU wiring wasn't quite...
Yeah, its handy to roll the car out of the trailer and drive it up to the pump. http://fsae.com/groupee_common/emoticons/icon_smile.gif

We're currently planning on being there. How'd your car run?

Unfortunately, I forgot that we loaned our trailer to the 1/4 scale tractor pull guys for the weekend. So we won't be there Sunday.
We'll probably try to make a couple of other autocrosses this...
So far UIUC is planning on running this weekend(June 1st) in St. Louis. Anybody else planning on going?

Since you were in Washington's paddock, I bet you saw us smashing that relay connector with a hammer on Sunday, followed shortly by the meeting with a propane torch. ...
For us, it was a connection to the fan relay that fell off. I was apparently hitting it with my knee everytime I was on or off the gas. We made about 5 laps before we overheated and they pulled us...
