Because the pray on the innocent all sounds good but who fits a clutch and the gives feedback. Many people are still fighting for money after fiting said clutches.
Buy from a dealer Matt lewis. Woodford garage. Burton power etc.

But please dont forget to have fly skimmed and bed in.
I have 400 plus lbft so the organic was no good for me.
My mate is running 347 on greens and gives it death with a ap organic clutch.

Hope this all helps yet a little late...
