yes they do. extra stuff depends on how much you want to lower your car.


Why drive a Prius when you can have a Fiesta!!

All you need is lowering springs if you buy springs that lower your car more than 1 1/2'' you will need CC plates.

I'd recommend you look at what the car needs to do for you before you decide how much to lower it.

Maintaining that OE ride is easiest done with the Ford Racing spring sets out there, with about 3/4" drop the most before you start sacrificing ride quality.

If ride quality is less important than handling, consider buying your springs from a company that sells the whole ball of wax. Maximum Motorsports :: The Leader In Mustang Performance Suspension , Steeda Autosports | Everything Mustang Performance , or many other sources offer everything you need to transform that car to a real road track handling machine.

If you want the car to drop more than the 1.5 inches mentioned by lxarlo, it does indeed get more complicated. Steeda suggests adding their torque steer kit at that point, and I agree with them. CC plates are a good idea because they can help correct the changed geometry created by the drop in ride height, and allow adjustments on the track, which can greatly aid handling in those conditions (though you want to keep those adjustments more neutral for the street).

There ARE other alternatives for lowering your car. The most expensive is Air Ride, which will allow you to drop it at shows down to the ground - raise it high for street driving over speed bums and such - and lower it to match the needs of a road course. The other, less expensive (though considerably more expensive than a simple spring swap) alternative is coil-overs, which replace both your existing shocks and struts and springs. These come 2 ways, with single and double adjustable versions (the double adjustables cost considerably more).

A lot depends on where you are going with your plans for the car.

For a simple street car daily driver, my advice would be to drop it 3/4" and compromise...

But for that mean look, I know that more is more...

Its the choice you ahve to make. I went toward the edge of the road course route with my 2002 and a bunch of Steeda parts. She rides a bit rough, but handles like she's on rails compared to where the car started.

Cool

Agree with stan, recommend looking 'whole' systems vs buying piece meal or ebay a la carte.
Also, do you have any mustangs in your local area you can ride with to test? Experience always helped me with those decisions.

Isolated

Regardless which spring option is chosen, replace those worn out rubber isolators! A 9 year old isolator is junk, period. And DO NOT go without the upper isolator just to get an additional 1/8 inch drop - the difference in noise and vibration transmitted to the body is real.

I went with H&R super sport springs which slammed the car and I had it aligned and seems to be wearing tires fine with out any kind of CC plates. You can really feel the big bumps in the road though hahah..
