MMCO-1 Mustang Front Coil-Over conversion kit for Bilstein struts including springs. The MM Sport Valved struts make a great all purpose choice, but the MM2 Race Valved or MM3 Race Valved struts work better for track only use. This kit comes with Hypercoilsprings in your choice of spring rate. Read the Guide to Choosing Spring Rates and Dampers for help choosing spring rates for your mustang.
Read the MMCO-1 installation instructions before ordering. View the MMCO-1 product page for more details about the coil-over kit itself.
