check out the threads:
suspension vs limited slip
How to set up LSD: 4WD cars
How to set up LSD: RWD cars
How to set up LSD: FF cars
Read through these; while they are more directed toward LSD settings, I think you'll find some links or, at least directions, to some great explainations on suspension tuning.
If I can offer one additional piece of advice, when you're starting out, look for posts that explain the hows and whys of tuning (rather than just finding settings for a particular car). Teach yourself to fish, you know? :goldfish:
Good luck, and welcome to GTP!
