SharkAttack99, I have run Buku and perhaps can provide some feedback. As everyone is aware the key for clutch selection on the savage is to ensure the the shoes don't hit the top of the bell. This is challening due to shallow bell wall depth. In general, the clutch nut length defines if you can run the clutch, However, Buku is a little different, as there are a few prequisites than decrease the end float, thus marin for error.
If setup and/or tuned incorrectly it will cause you problems. Flywheel requires 1+ shims behind the collet. This eats in to the end float and the spacer cannot be used at this point (so sugest getting a shim kit). In a pefect setup you will have ~ 1.5-2mm to play with before the bell hits the shoes or the bell hits the spur. I've run ABK (both m and h) and BBK. Preference is ABK (h) depending on the engine I run and where I'm running.
New bell is a must. Contamination of material (even nylon) will foul komposite within minutes. These shoes do not like hot bells. You're bell will most likely change colors (on the outside as well) just keep an eye on it
Regarding the clutch tune, the engagement settings are akin to .70mm to 1.5. This also means larger margin for error if you are unsure how to listen to your clutch. The komposdites were designed for staggered engagement. While you can set each the same for a more abrupt, violent engagement, it's another clutch. But leveraging the tension window to get the first shoe to engage as quickly as possible without bogging, then setting the remaining two so they are progressive gives the truck an "electric feel". Accelertion is instantaneous so to keep it progressive timing of the next two shoes isn critical. Takes some practice but once you get it set up it is impressive.
Some people have had success setting all shoes to engage at once. As with all clutch systems as long as you have available traction to pull that off you are good. which is nice assuming you can get required traction as those BBK induce quite a bit of torque. If traction is lost and wheels spin, bell gets hot and komposites can ultimately become rendered useless.
So the principles are same for any aftermarket system with the Savage, you just have to be spot on wit it or the clutc will hinder performance.
