Finally decided to crawl under the Speedster this weekend to address the lowered car that was a bit twitchy/ scary as speed increased. Prior to this I replaced all four ball joints and tried to adjust the toe-in as well. After a little wrestling match with the front beam I was able to put in one caster shim(about 6 mm at the center of its crescent shape). I wanted to put in another but couldn't get enough leverage working with the car on jack stands. No need to get greedy as I really wanted to do one then see what the difference was on handling/stability. I'm here to say it helped a lot. The car is now more stable, tracks better, I was able to attain a higher speed without feeling like the car was hunting for a direction on its own and it has something I haven't experienced with this car yet: a little self- centering after taking a corner. I like it, I like it very much.
If any if you have yet to make this adjustment to your car and feel it may be of benefit then run, don't walk to CIP1 or one of the other folks offering these and buy them. For the cost of a decent drink out with your spouse you can do this too.
Thanks to all that have posted info. on this topic so others can do research and get religion!
