Billy- I have not tired them yet... yea I know I'm a failure lol. I will soon though. I'm just waiting on them in the mail.
RCFREAK- Ackerman adjustment can have some varied effects depending on how much grip the track has... but usually more shims (like 4mm) makes the car more reactive initially, and less steering through the middle and exit. Fewer shims (like 1mm) will generally smooth the car out a bit, but give more steering through the middle and exit.
Hope that helps
