I haven't tried my car without the risers and standard towers, but It's something I'm going to try this weekend.

aus - i have no answer for asphalt. most of these other guys can help you out.

I've run a rubber car without the diff risers and foam shock towers...works fine

You can run the car without the diff risers and the standard towers. You just need to run the upper hole in the rear tower and slot the front tower camber link hole up 2mm. This is how I've had my car since the Reedy Race and it really seems to help with the overall cornerspeed.
And Goetz, Weylin is right, you're a geek, but that's a good thing.

yeah, the sad part is that we all sat there as a freshman in high school arguing that this stuff didn't have a practical application. now, as adults we label this stuff, which is suitable to be taught to 14 years olds, as "brain surgery". that's friggin' awesome.
i'm actually disappointed that i don't have the program we used in school for kinematics (matlab maybe
). it allowed you to create a bunch of links (not hyperlinks children), and it would show the input and output angles, and their relationships and such. the realistic application here is to model our suspension in order to determine the appropriate tie rod geometry to give near zero bump steer for the whole usable range of travel. it would map out the steering ball arc, and we could estimate the center of the circle, which is where the link would pivot on the rack. 
then we could bump in/out from there. it's more complicated than that, but you get the idea.
by my own admission, i think we could do it by hand using diff-eq, but i'm not that ambitious.
suck on it.

It wouldn't be too hard to model, since an RC suspension is a simple 4-bar linkage.

smooth, you're going to be denied admission to the gate this weekend, if you don't have a copy of that sofware in hand.

I'll bring a coffee can for donations towards the $4,000 cost of the software and license.

i would advise you to bring jacket as well.

We know you were the one taking the picture Korey.

If you need it i can find it. Mathworks Suite Release v. 13 with matLap v. 6.5.
If this suite includes what you are looking for let me know. If not, give me the actual packaged name and version.
