Front end height question
 
Going to install a pair of Landrum springs.
If the ride height is too high do I cut them or exchange them for a lighter pair?

I would exchange if you can!

Don't cut them. Let the car settle on the new springs. Best to get the car on 4 scales and see what the corner weights are, with and with out a driver Check RR for Preload..

From one rate to the next, it will change the ride height about 2 1/4 to 2 1/2 inches. It?s not an exact figure, but it?s a good ballpark to go off of. If you need the car to set less than 2 inches from where it is now, you will either shim it or trim a small amount off of the spring. Depending if it?s too high or too low.
It usually settles very little. But they will settle a little bit.

If you have any questions, feel free to call me

In my experience, a Landrum will settle a little bit then be good. The other spring people use will settle through the life of the spring and need replaced eventually.

I will trim a spring, but not much. 1/2 a coil maybe. Even trim a bit more on one side if needed. Trimming the spring changes the rate.

If you trim coil springs, a very accurate rule of thumb is that for every inch you want to reduce ride height, cut half an inch of spring height. For a 2" ride height reduction, cut 1" of coil spring height off.

Yes,
that?s another rule of thumb to go on.
Thank for bringing that up

Marty, One of the pains was every other year replacement of the front spring on the F-Body. I wondered if this was still down in the box, so I just walked down and looked. Here's my old templet for the Moroso 210s in that car of Hunztberrys. With the Morosos, on this car, I found you could cut...not much movement. Cut the same amount.... not nearly enough. Another inch, same thing. Simply cut that same amount and the car drops 2 solid inches! You just ruined a set of springs. For that reason, I kept a templet. If I would have kept it, this was going to be on the to do list. Landrums ....

I?ll be starting with a pair of 200?s to replace the cut old Moroso spring that are almost on the bump stops.
