I actually did quite a bit of reading on the pro's and con's of cutting my stock springs. I ended up deciding it was going to be just fine for me. I cut 3/4 of a coil in the back and 1 full coil in the front. I added MM caster/camber plates and headed straight for the alignment shop. That was 2 years ago and I've experienced zero negative effects. Ride height is spot on and ride quality was not affected enough for me to notice whatsoever.

What are the CC plate for?

What are the CC plate for?

To get a proper front end alignment. Any lowered car, whether with aftermarket springs or cut stock ones must be aligned after install.

^^ CORRECT lol

i like my 4x4 stance and ride.i had the eibach pro kit and had it aligned and liked the stance but the ride was bouncy as hell so i went right home and put the stockers back on. is there any lowering kit that will not be bounce me like im driving a jeep through the woods.

^^ my cut rear springs dont bounce at all fells just like stock havent dont the fronts yet so i dont know what thats going to be like

Spring delete!

Spring rates are off. Therefore causing suspension to wear faster and bottom out. So who's is worthless.

Cutting a spring does change its rate. The rate will increase. How much depends on how much is removed, how many coils the spring had to start with, and many other factors. How does this cause faster suspension wear?

they wont bounce if you update your struts, when ford designed the mustangs suspension they generally shot for a hair under critically damped systems.
Long story short this is c^2=4km (critically damped) c being your damping coefficient, k being the spring rate and m being the mass of the vehicle (well ~1/4 of the vehicle for each wheel, but anyways...)

Anyways, when adding lowering springs the k value has to go up becuase if left stock it would bottom out like nobodies business. So, if the c is left as it is the system goes to c^2<4km and it will become bouncy. SO if you don't want to replace your struts shoot for a spring with similar spring rates as your stock springs.

Hope this helps

But remember that a shorter spring of the same rate will bottom out from less load than the long stock spring.
