When I redid my front end, I magnafluxed the uprights and put in alloy spindles,(Ihttp://www.leechapmanracing.com/lotus_elan.html) I also installed bearing spacers to stabilize the front wheels to improve high speed steering stability. It seems to have been successful since I regularly take it to 90 or so on the expressway. I sure would not feel comfortable do that before, since the car was very twitchy.
I have not raced the car.
