1. CPP’s bolt-on Mini Subframe front suspension kit can be installed in a weekend and it is easy to install once all of your Mustang’s worn out parts are removed. You get the ¼-inch-thick steel crossmember that either bolts on or can be welded for exceptional strength. Upper control arms will accommodate the stock spring perch and coil spring or these adjustable Viking Performance coilovers. You can use a stock sway bar or this powdercoated bar from CPP with billet aluminum mounts. Adjustable coilovers allow you to tune ride quality, handling, and ride height.
