the yellow shoe is a harder compound so does not slip as much and has a higher grip on the cluth bell. The original white one wears down a lot faster and tends to in my experience to slip more as less bite on the clutch bell.

The video clip is choppy..... IF I watch the video clip AS IS, yes, your clutch is slipping. The engine is screaming, and your car is not moving as quickly. There is late factor ( not responsive to throttle input )

Loosen the centax spring locknut by half turn.

Do you shims correctly the clutch gap and end play ?

You should also check your clutch spring, it can get old and become softer, so it can not push the shoe hard enough to bell.

Sanding the shoe and bell where they meet together, or replacing them with new ones would be a solution as well.

i am pretty sure that the clutch gap and end play is correct, so i will losen up the spring a little, i am using the hard spring, maybe that is why it is not engaging early and the respond is not quick, will be checking the clutch tomorrow and will certainly sand down a bit the clutch and the bell. thanks for the respond guys

I think you mixed up on that sentences. The centax spring push the clutch shoes towards flywheel.

The problem with soft centax spring is bogging. The clutch engage at lower rpm, creating bogging effect.

No, I mean when spring is too soft, shoe touches the bell very softly, so it causes slipping. If it doesnt slip, engine will bog because of low rpms. Thats what I think.

From what I was told it works well on low bite tracks since it has the tendency to slip more then a standard clutch. But I've yet to actually use one so thats all second hand info.

I have seen the clutch on Dirk Wischnewski's car(BumodGP champion) and believe it improves acceleration and its lighter. Mine is coming so Im going to give it a try this weekend. (Bumod is a HUGE track with medium grip.)

I would advise to blow the track first with a blower
