Russell,
Russ started this excellent thread which is a great read:
What Causes Heavy Steering.....
When you've finished with the thread, you'll have a good understanding of setting up your car. There are a number of really good threads in this section you should probably read. Another is the one that discusses the rear suspension bump steer correction on Jim C's car:
Rear suspension bump steer. Ron's thread:
Performing Alignments is another really good one to read.
If someone wanted to take the time to compile the chassis information contained in this area, they could publish a world class book on the subject.
Regards,
Lynn
