basically since our cars are slammed, Matt and I were trying to think of wayys to correct the geometry in the rear. You can get custom rear knuckles that make everything mount lower making all the arms straight but they are expensive and hard to find. This helps with that and if you do both the risers and the knuckles it'll be as if your car isnt even lowered. pretty cool. And the solidness keeps slop out of the chassis.
They work great but it will take some time to release because we have to do a huge production to keep the price reasonable - the one offs were expensive!!!
