You stated that you will process your scans in GeoMagic X.

Do you know of a less expensive option to the GeoMagic X software?

with those mods you will probably be in E/M which is E Modified

go to the corvair autocross page for some guidance

I think Autodesk may have software that would work. It’s called Fusion 360. Haven’t tried it but I believe some have used it. It’s $60 a month.

Other than that you might be able to get by on free trials.

Hi Sean,

I can comment on the first two, at least a bit. At the National level you're building an E-Mod car, which is pretty open (thus the name).

There are also a set of regional level rules based around CAM called Xtreme Street that may better fit your build, if you're building a street car - you're allowed to do all sorts of mods including suspension/engine swaps, but you have to have a finished interior and be street licensed and insured.

The really big difference between the two in my view is that Mod allows race tires, while XS allows 200TW street tires. That will greatly affect the suspension setup (springs, shocks, alignment, etc.)

If I were building a car like this for 200TW tires, I'd allow for camber up to 5 degrees static without screwing up the camber curve. You probably wouldn't need that much, but 2 to 4 degrees is what most of these tires like. I wouldn't assume any Corvair settings are especially applicable here since it's really not a Corvair from a suspension perspective. Maybe talk with the Vette guys to see what they run. FWIW I'd probably also put in air conditioning :-)

Sounds like a great project, good luck!
