Procedure
Installation
- Step 1
Remove the primary and secondary outer cover. Locate the primary clutch.
- Step 2
Either pull the belt and primary clutch or loosen all (6) M6 primary clutch cover bolts with the primary clutch still in the car. Only take (3) all the way out.
CautionApply pressure to the primary clutch cover when removing the last (3) bolts.
- Step 3
Place your new EVP Shift-Tek Silver Spring onto the primary clutch. If you are not changing out the OEM weights you can re-install the primary clutch cover.
- Step 4
Reuse the OEM (6) M6 bolts to mount the primary clutch cover.
NoteWe recommend replacing the OEM primary clutch cover with the EVP Shift-Tek Billet Clutch Cover. Sku number (401FP0014)
- Step 5
Torque the M6 bolts down to 100in-lbs (8.3 ft-lbs).
When you’re done
After installation
Note
- Silver primary spring used with stock clutch weights, engagement is 2200 RPM.
- Silver primary spring with Shift-Tek clutch kit, engagement is 2600 RPM.
- The silver primary spring will raise the RPM’s enough to use launch control with the stock weights, but it is not recommended.
