    I see a lot of threads of people asking things like, "How low should I go?" "Are wider tires always better?" "What wheel offset should I run?" "How much camber is too much?" ECT...

    Well, I came across this quick little guide, in my book for my suspension class, that I think people could reference just for a ball park idea for what you want/need.

    Let me start by saying it's not a perfect world. There are pros and cons to everything so you just have to take the good with the bad...

    Change - Positive Effect - Negative Effect

    Increase Tire Width - Increased Dry Traction - Hydroplaning in wet conditions, Requires wider wheels(in some cases), Reduced fender well clearance

    Increase Wheel Offset - Increased track width, Reduced weight transfer - Aerodynamic drag, Increased wheel bearing load, Reduced tire clearance

    Lower Center of Gravity - Reduced weight transfer, Reduced body roll - Reduced ground clearance, Reduced wheel travel

    Increased Spring Rate - Reduced body roll - Increased bump shock, Harsher ride

    Increase Negative Camber - Increased tire cornering power - Tire wear, Steering/Braking pull, Reduced straight line traction

    Increase Positive Caster - Straight line stability, Improved camber on turns - Harder Steering, Possible shimmy(wheel shake)

    Lower Roll Center - Less camber change on roll - Increased tire scrub(tire changing path/direction) on roll

    Replace Suspension Bushings w/More Solid I.E. Polyurethane - Reduced alignment deflection(roll steer), Faster anti-roll bar response - Increased vibration, Harsher ride, Replacement bushings usually require lubrication
