Screaming eagle variable clutch plate

i purchased the AIM variable clutch pressure plate. I currently have a Barnett spring in stock clutch—- 113 ci motor
If my memory serves me correct I have the HD 110 spring which is .020@ thicker than stock. The Barnett spring is .020” thicker than the 110 spring and is definetly coming out.
Do I put stock spring in or the 110 spring in with the screaming eagle variable clutch pressure plate.
Thanks in advance

You use the correct AIM spring! IIRC when buying their VPC it comes with your choice of suitable spring. That's how they can claim that lever effort is up to 40% less, due to using a softer spring. If you don't have an AIM spring then check their website and get the correct one. I wouldn't use either of those you currently have, they sound too much.

Here are the thicknesses.. The AIM 480 is the same as Barnett heavy..

I would keep the Barnett spring as the VPC changes the fulcrum point on the springs to reduce pressure. It really depends on which AIM VPC you use tho. Some reduce a lot while others only a little.
