Well i didn't research
They really arn't bad at all. My friend is running them on his built turbo gsr da integra with KYB agx's and they ride fine. They are a little stiffer than most but no where near as stiff as skunk 2's. Throw them on your car and i gaurantee you will be satisfied especially for the price.
