I've been thinking aobut doing a 20" wheel/tire package with my '01 Lightning, but the quesiton remains: what will it do to the handling characteristics?? The suspension was designed with 18" rims and 45 series tires, specifically, raising the center of gravity 1" (using 20" rims and 45 series tires), will also raise the roll center 1". Given that the suspension was designed to keep the tire as flat on the road during body roll as possible, will this 1" rise change it drastically enough to cause undesirable handling characteristics??

Any input would be helpful and appreciated.
Thanks!
