Dude, **** what people recommend. Shops are trying to sell you what they have in their inventory.
Both the clutches you mention are only good to 350 ft/lbs. of torque approx.
With your setup, you have way more torque possibilities than that.
now how am i soppouse to know what clutch to buy ? there are hundreds of brands and models, if i don't ask a shop that sells parts, who am i going to ask ? tell me FOCUS what clutch do i need ?
