Is the geometry and measurements for the ef chassis posted anywhere online? I am looking to do some math on that car to compare some setups, but have no measurements to go from. Thanks!!

Edit: Won't have the car for a bit, so I can't do these myself yet hahah. So that is why I am asking.

body dimensions for the sake of body work is available in the factory service manuals. i dont think ive ever seen it scanned on the online copies, but its in the hard copy.

 

What I am really looking for is dimensions for like swaybar section lengths, measurements of the control arms, trailing arms, that sort of stuff. Not posted anywhere?

not a chance.

 

I'm actually surprised by that with how deep the chassis is into racing, that nobody actually took the time to figure out the numbers to get the natual frequency of the car and base some spring rates off that.

We just finished mapping this all out for the saturn s-series, and it's pretty interesting playing with the suspension calculator and different setups with it.

that is probably due to the fact that the rear suspension is less than conventional and most "conventional wisdom" in relation to plotting suspension geometry for a wishbone suspension car is based on a pretty standard wishbone model. Any deviation from that, like the type of nuances you would find in the rear suspension of a semi trailing arm style civic, would be infinitely more complex for an amateur to plot.

also, in your first post you mentioned that you were curious about suspension geometry which i read to mean that you were looking to calculate roll center, scrub, roll couple, etc. but in the post above you are talking spring frequencies which you should be able to find all of the elements of that equation online (sprung weight of car, stock spring rate, wheel rate, etc.) to plug into some simple formulas you can find in any suspension tuning book worth it's salt.

what exactly is it that you are looking for?
