I recently lowered my '99 and am afraid I went too much.
In order to monitor the change, I painted the wheel well white to see if there was contact. These pictures show the drivers and passenger side after a weekend of practice and 2 races.
Thoughts please.
With the suspension loaded and settled, measure the distance from the top of the shock to the bottom of the bumpstop. 3/4" is a good ballpark figure to start with prior to setting corner weight.
