High Speed Stability
#11
at 140mph you'll feel the car lifting the front end a little in stock form. The steering being touchy at that speed combined with the lack of contact to the road from the tires makes it fun. So anything to add some extra down force to the front is what you really want to look for if high speed is your main concern. At 110 the car is still very composed and barely even a noticeable difference from lower speeds. Its just a little after that where things start getting crazy. But this is just what ive experienced. Also i should note it was in a vert so the aerodynamics are a little different and could factor for a good variance in what youll find yourself.

Loose the reactive 4 wheel steering (rear-wheel steering): http://www.mazdatrix.com/rmounts.htm part #04-7402-0000-KT

if you're going to do a full undertray you do not want it completely smooth, thats how racingbeat basically launched into orbit. look into the proper way to do a full body undertray, for instance look udner a new lotus elise.
my t2 was stable at 150mph with manual steering and a dead on alignment with my own custom specs, being able to do your own alignments helps a lot in this area lol.

Toe-in
more front caster
real front splitter/spoiler/wing
Rear wing (will kill your speed)
I'd say keep the DTSS (rear-steer system) it's there to keep your car stable, not the other way around. Unless your DTSS is messed up/broken due to use and age, then swap it out for Eliminators.

look at the bottom for the undertray.
the F355 used a completely flat under tray to reduce turbulence and lift. The elise does have a different type of undertray that is like the under tray labeled "ground effect" on that site. Using the ground effect you can get more down force. fitting one of those to a FC would be rather difficult. you probably could do something like that if you ditched the gas tank and spare tire holder or if you didnt mind having no ground clearance. I dont know what sort of work you do, but if you could make a scale model and do some wind tunnel testing or run tests in CFD software before you actually strap your contraption to your car and goo 150. I am planning on building a full under tray at some point. I just havent had the time to cad everything out and run the simulations on it that i want to.
