Adding coilover struts to your Mustang has a variety of benefits. The first noticeable advantage was the ability to adjust ride height. The other is to get a better front spring to help transfer upon launch. Granatelli includes two spanner wrenches to crank the collar up and down. All too often, people want to crank the coilovers down so much that the front end is on the ground. Running it that low usually isn't the best method, as weight transfer suffers, as well as ride quality. We kept the ride height near stock for two reasons. One, was to let the springs settle for a day or two. The second was because we are going to be overhauling the backside and felt it would be better to adjust the front and rear ride height at the same time. Granatelli sent us 300-pound springs because of the car's status as a street machine. Spring rates are a touchy subject, depending on who you talk to. You don't want a spring that is too heavy, otherwise weight transfer suffers and ride quality will be harsh. However, a really light spring might not support the heavy front end of a street car. A light spring will also cause a rather soft ride that can result in too much oscillation on bumpy and curvy roads.
The trick in selecting springs is finding the proper balance; the 300 pound springs we employed should offer great ride quality, but definitely aren't for the hardcore drag racer. "The best method in determining the front spring rate would be to weigh the car on four-corner scales. But generally, in a Mustang with a supercharger (which is nose heavy) the 165-pound springs will work nicely for hardcore drag racing and limited street use. Naturally aspirated cars can run a 155- or 160-pound spring. If anything, this car will ride as nice as it did before with the four-cylinder springs," comments Dennis McPherson of DMC Racing. The springs are great for a daily driver; just don't expect a 300-pound spring to help a car like this leave the starting line like a NHRA Super Stocker. Granatelli offers a variety of spring rates, selecting what is best for your application is up to you.
