I have a Vee Two clutch drum with four posts, so I need four springs.
I have four heavy duty oem springs that came with it. They appear stiffer than other oem springs (thanks He Man), but I also have TPO springs which are stiffer and in my experience, the heaviest rate available, regular oem that are softer, and Barnett which appear to be rated somewhere in between regular oem and TPO.
Do Barnett still offer different spring rates for different applications? I could not find a selection of rates on their website.
Anyone in their experience know which brand of springs would be a heavier rate appropriate for a four post drum?
