VSP custom modified Primary clutch

This is a custom package we are offering to our customers. We have found the P22 clutch and the P 85 clutch to not hold up to tuned boost sled very well. Performance reducing drastically after 600 miles of hard riding even with new belts. This is caused from the bushing wearing out and the clutch becoming sloppy. We have run this for a season on the snow and have found it to be a very durable solution. We have seen the following gains 

-Increased durability 2500+ miles and still tight at tuned hp levels 

-Roughly 1.3 lbs lighter then p22

-Better acceleration 

-Better top speed 5-7 mph commonly seen

-Better hp to the track 

-Able to run 15-20 grams less weight 

-Lower start ratio 

Llower belt temps
