Lowering Spring Kits

How Much Drop You're Getting, and What Changes With It

A set of lowering springs typically drops a Mustang by 1 to 1.5 inches, though the exact amount depends on the spring rate and whether the front and rear rates are matched. That drop comes out of your suspension's usable travel, so the shorter your springs compress the car, the less room your factory struts and shocks have left to do their job before bottoming out.

Springs alone work fine on struts and shocks that are still in good shape and rated for the reduced travel, which is most of what a moderate drop asks of them. Push past that range, or pair springs with shocks valved for stock ride height, and the ride becomes harsh, or the struts wear out faster than they should. Some owners also notice the car settling unevenly over the first few hundred miles as a progressive-rate spring seats in, which is normal and not a sign of a bad install. That's the point where a shock and spring kit or a full lowering kit matched to the new ride height makes more sense than springs by themselves.

Why Our Mustang Lowering Springs Outperform Generic Linear-Rate Springs

A lot of lowering springs on the market use the same linear rate front to back and call it done, which leaves the car feeling stiff in one end and soft in the other once it's loaded with a driver and fuel. Our Ford Mustang lowering springs use rates calculated separately for the front and rear, so the car settles evenly rather than leaning toward whichever end got the wrong spring. Plus, their powder-coated finish holds up against road salt and grit that eat away at unfinished coils over a few winters.

Balance is also why performance lowering springs are only one piece of the equation, not the whole answer. Springs set ride height and spring rate, but damping still comes from the strut or shock, which is why we build our coilovers for owners who want ride height and damping adjustable together instead of locked in at install. Choosing between springs alone and a full coilover setup comes down to how much control you want after the car is already on the ground.

Frequently Asked Questions About Mustang Lowering Springs

Will these lowering springs work with my factory struts and shocks, or do I need new ones?

Factory struts and shocks in good condition handle a moderate drop fine, since springs alone don't change the damping, only the ride height and spring rate. If your struts are worn or you're chasing a more aggressive drop than the moderate range, pairing the springs with a shock and spring kit valved for the new ride height keeps the ride from becoming harsh.

How much will my Mustang drop in the front and rear with these springs?

Drop varies by generation and by which spring rate you choose, and the front and rear numbers aren't identical since we calculate the rates separately for each end. Check the listed drop for your specific Mustang year before ordering, since a 2005-2014 spring and a 2015-and-later spring don't drop the car by the same amount, even at a similar rate.

Do I need an alignment after installing lowering springs?

Lowering the ride height changes the angles your suspension operates at, which shifts camber and sometimes caster enough that your old alignment numbers no longer apply. Plan on a full alignment once the springs are installed and the car has settled.
