Consult your MM sales department for help choosing spring rates for your particular car and performance driving habits. This kit can be purchased without springs as a MMCO-4.

Fits Bilstein and MM valved shocks:

If you have Ford OEM 2003-04 Cobra Bilstein shocks (already grooved) and wish to use them with your coil-over kit, you still will need a MMSM-10 kit to properly complete your installation. See the product page for details about the differences.
