SN95 How Low Is Too Low?

You should be bant for that image.

Unfortunately, you really can't go much without it being considered "too low".

It's not that these cars are high, they just have huge fenderwell gaps. Lowering the car is an attempt to reduce that gap to make the car look better, but unfortunately you change the suspension angles for the worse.


Bullitt springs are prob one of the better springs you can put on a fox, but don't count on it to lower you. If you want to go lower, remove the spring isolators, or cut off 1/4 to 1/2 a coil

Well cutting the springs that's just a no no

Cutting progressive rate springs is a no-no. Most mustang springs are.

03/04 Cobras and the 01 bullitt and 03/04 mach 1 use linear rate springs.

Linear rate springs can be cut...slightly. 1/4 turn would equal 0.25" or so in total hieight reduction. Not a significant difference in K-value (spring rate)...especially if you are cutting the dead coil which doesn't do much for the rate. How much is too much? That's the tricky part.


I'm too lazy to look up numbers to calculate it out, but here's the formula for linear rate springs

k = d^4 G / (8 D^3 N)

d = diameter of the wire
G = Bulk Modulus (material property)
D = Diameter of the spring
N = Number of turns
k = spring rate


I believe in stock form, the springs are 600 lb.
