About our recommendations:
We have first hand experience with these clutches including
installation, street driving, race track driving, and compatibility
experience with cars producing increased horsepower. Based on this
experience, we have recommended the clutches above.1: Torque capacity is a rating of the
torque a clutch can hold at the flywheel once under normal operating temperatures and
once fully engaged. This number is generally a rough calculation based
on the surface area, friction coefficient, and clamping force used on
the clutch. It should be noted that this figure is based on the clutch
being fully engaged. Note these numbers are manufacture provided
and/or estimated values.
2: This is a estimated rating based on the amount of effort required
to actuate the clutch pedal in the cabin. |
