Mustang II springs
 
After installing my heihts front end according to directions, I had to cut 1.5 coils off the lightest duty springs to get the lower control arms level. All looks ok so far, but my shocks only have about 1.5" more travel til bottoming. The car only weighs 2700 lbs. Any thoughts?

Willy Carquest and napa have shock books that have the sizes and travel listed.(borrow it over the weekend cause ther are thousands of diff ones) Measure your eye to eye lenght at ride height and go from there(mark your old shock with a magic marker before you remove it ).Just try to get at least a 6 inch travel shock for the front .I try for about a 8 inch travel for the rear. I use gas shocks in the front and regulars in the rear with the cars we build.After you cut the coils did you let it sit or drive it for a week or so cause it will settle more. good luck

Phat: Have you run into the necessity of cutting down the springs on a stang II front
in order to get the lower arms level?

I ran into the same problem about ten yrs ago with a must. 2 frt that I installed in a 48 ford. I never did find a short enough shock to have sufficient shock travel. I ended up cutting the centers out of upper hats and building extended shock mounts. Was a real hassel and never was completely happy with results. The next car I built using must.2 (41 Merc) I had the crossmember designed as low as possible and only had to trim 1/2 coil off of 4 cyl. springs. - worked and rode perfect. Can only suggest you contact Heidts and see what they have to say - would be interested in what they have to say. Good luck

Yes everything that goes out of the shop ends up with cut coils.Its the last thing we do with the car completely done(i allways error on the high side cause they settle) I also use 4 wheel scales and a spring rater to figure out what rate spring to start with.(some times i may go through 2-3 sets of springs and a couple sway bars to get it just right)With the shock book you will find a correct shock now a days with out cutting. Some of the shorty shocks made for the lowered import truck crowd work pretty well also(tripped over that by acciedent)

Tinhunter & Phat Thanks, that eases my mind. Heidts basically told me the same thing. I'm having to cut 1.5 coils off the 4 cyl springs
to get to level. I will try to get it just above level to allow for that settling. I can get a little more out of the shocks by removing the shock snubbing rubber, but I'm sure that not a good idea.

Thanks Brad for the info.I have a 70's Trans Am column.

Willy i do suggest only cutting 1/2 coil at a time. Do the shocks last. Post back if yah need more help.Rule of thumb the 4 cyl springs are soft but work ok when cut(the rate goes up as you cut them shorter)If you start with V8 springs and have to cut them much the rate gets rather high(600-900 lbs)
Good luck Bud

Phat, thanks, I sneak up on it when I install.
