Stay awAy from the ksport it's garbage. The Cnc one is kind of flimsy and you have to make a bracket to mount it. The one I would suggest over all of them is powered by max.
Both Paul and Rhythm Drifting have a CNC Hydraulic Ebrake. The only K-Sport I've seen is garrrrrrrrrrrrrrrrrrrrrrrrrrrrrrbage.
But don't take my word for it. Ask Ter-Tech.
