We have an '05 Saab 93. We found some used Ksport coilovers to stiffen things up, and have 3' camber on the front. This dramatically helped the typical understeer into corners.
We also did a lot of weight removal in the car. It was a convertible so we removed the top. The final weight distribution is 64% on the front wheels, 36% on the back.
With this weight distribution and the tighter suspension, we have the back end go out on tight corners. We basically have no braking at all on any slightly turned position of the car downhill without it wildly swinging out. It gets a bit loose in chicanes because of this.
I get it won't help on slow speed corners. I'm hoping it may help us push faster through carousels, e.g. rather than spin out hopefully all four wheels would slide to give us a chance at recovery. Maybe more stable in chicanes such as the back part of the Sonoma course.
I love the idea of incorporating the airplane theme for a wing into the Saab theme. I'd prefer some option to make it out of aluminum versus the pain of dealing with fiberglass if possible. So far I've only found examples of folks making fiber glass ones. There's also super cheap wings and spoilers on ebay though I am quite skeptical those will be functional.
Hints, tips or tricks on how to build this would be awesome.
I love the bowling ball / ironing board example. So far that's our front runner for what to do.
