I ask because one of the tracks in my area has some really bad bumps at a few long bends. When I hit them at 70-80, my car sort of absorbs them on the inside while keeping the outer wheels planted. I always wondered what would happen if I switch to SPL...whether suddenly my outer tires are going to be upset as the bumps cause the coilovers to bounce more and lose contact with the road.
My friend has a Lotus Exige S, and that's his main problem. He hits the same bumps I hit (maybe ~5-8 mph faster) and his car begins to lose contact with the road. I guess being ~2000 lbs also doesn't help.
