Can I run a clutch mod without a clutch cushion kit?
Yes. A Brock's Performance Clutch Mod can be run independently of Brock's Clutch Cushion.
***BUT*** a Clutch Cushion CANNOT be run without a Clutch Mod.
A Brock's Performance Clutch Mod is designed to simply eliminate or disable the OEM slipper clutch to improve dead stop launches.
The Brock's Performance Clutch Cushion is designed to allow the rider to dead stop launch as smoothly as possible. Of course, this is not possible if the OEM slipper is allowing chatter/grab.
