Here are dyno charts for my SD Bilsteins. They had an insane amount of grip in dry and wet. I've always felt confident driving the car at the limit (or as close to it as I could get, given my very limited racing experience). Mono Flex felt just as stiff on hard setting but they are adjustable and are alright for street driving on softest setting. I've never felt as confident driving on Mono Flex, but that may have been because that particular car had ~100whp more. That said, I don't think I'll be buying another Tein product.

FM Vmaxx is the best bang for the buck if you are looking for an affordable dual duty setup.
