First off, thanks to everyone who contributes to this site, its a great resource to have. Been lurking for quite some time and now its time for me to give back (a little bit at least).
The plan is to build a hybrid frame using four curved main frame rails (At-om-ish) but with the F20C engine from a 2001 S2000. Car will be street legal and used for mostly spirited curvey roads, trips to the Dragon, and possibly autocross or track day (never done either). Donor was bought back in '06 and has 45k miles on it. The stock rear subframe will be used along with the spindles, control arms, half shafts, & differential. I am giving up a weight penalty but I know the whole package works and is already done. A custom front subframe will be made with custom control arms, Motive's nifty uprights, and push rod suspension.
Specs: (subject to change)
1200-1400lb dry weight
98in wheel base
4.5 in ground clearance
205-225/50/R16 (24in diameter)
stock S2000 wheels for now
stock length front steer MG midget steering rack (26in)
minimal body panels
Corbeau Clubman seats (if I recall correctly)
one piece flat floor with sump above frame rails

I have been gathering parts for awhile now and started laying out the main tubes with pvc back in November. Not sure exactly how it's going to look with a front engine in an exoskeleton car, but hopefully I'll find out soon. I imagine an engine cover with probably a bump out for the rather tall F20C (25in) and a rear cover over the rear subframe and fuel tank.

I may modify the front diff mounts so that I can push the seats as far back as possible. I could cut off the bent rear sub tube and put in a straight tube and move the two mounts right above the driveshaft in the tranny tunnel. I would ditch the alum castings and make my own mounts. I'll see how everything lines out.

I started to use the stock front spindles but they are so dang heavy and have the uncommon inverted ball joint setup. That was until I saw Motive's nice uprights; lightweight, independent camber adjustment, double shear rod end mounts, use bolt on hubs. Recieved them and where exactly as described (in defense to Motive, the steer arm tubes look a bit rusty but he said he would buy some new steel to make mine but I told him not to worry about it and use what he had, just light surface rust)
