Metric car. What is the advantage of having the front rollcenter offset to the left vs just raising the roll center.

Po, according to Chassis R&D Inc., dirt cars generally "can benefit from having the roll center located to the left of the centerline. This is because the dirt cars do not experience as much turn entry deceleration forces as the asphalt cars do. What many dirt teams report is that by having the roll center located to the left of centerline, the cars will turn much better." Not a very scientific answer, but that's some information I've found.

I believe by using the taller ball joints in the right-hand side, that will move the roll center to the left. Correct me if I am wrong, I would like to know.

Po, the opposite is true. Remember it this way; the steeper upper A arm pulls the roll center to its side. You can draw it out on paper and see why, but take into consideration that these angles, lines, and intersections may move when the car rolls.
