guys with cut rear springs

I'm thinking about cutting 1 coil off the 4 cylinder rear springs. My question asside from looking better does it serve any purpose? Also I have 28 10.5 slicks and was wondering will they rub when lowered?

I cut 3/4" from my 4 cyl. springs and it lowered the car about half an inch, and I did not gain anything in my 60.

Mine have been cut to get the rear suspension where I wanted it. I use stock v8 stuff in the rear. The 4 cyl is just a little too soft IMO

Mine are cut 1 coil from an 03 GT spring. Its hard to say as to whether or not it will rub, you will just have to try it.

New times coming soon.....

about 2/3 of a coil from a stock 5.0 rear spring here. Just to get the stance right.

You have any pics and have you had any rubbing problems after the drop?

Depends. If you have it close to stock ride hight, its probably going to be fine. Lower it much, without the fender being rolled, and it (the fender) will cut the tire. You could probably get away with lowering it if its not driven much.

Its pretty easy to roll or cut the fender though.

Nice. Couple questions.........

How much would you assume it lowered the car with the cut springs in the rear? How low in the front?

I'm getting ready to do the same thing to my '85 Hatch. It currently has Eibach Drag Springs front/Rear. I also ordered the Eibach Sportline springs to get the look since I heard its not a good idea to cut the rear Eibach Drag springs. I figured I would try them for cruising (knowing they won't work well at the track or on the street for launching). My #### just sits too high and its driving me nuts looking at it like that........lol. Its got 15 x 9.25 w/6" backspacing Alumastars and M/T 28 11.5 ET Streets or M/T 28 x 9 ET Drags. The lips are not cut, but I imagine I'll have to cut them. Only had to beat the inside a little bit for them not to rub the tire on the backside.

Did you use top/bottom isolators front/rear on your springs?

Did you have to re-set your pinion angle when you lowered the rear?

What about offset rack bushings and frontend alignment when you lowered the front?

Off subject, but I LOVE four eye stangs. Well, not all of them, just 85 and 86's. Great looking car.

On a 150 hit. Its apart right now, I was having some issues with it, I was getting alot of blow by, and it was way under cammed. Pulled it apart and the engine builder had gapped the rings way wrong (.09!), and one cylinder was scored up. So its getting a new cam, a slight bore (will be a 363 when it goes back together), and will hopefully be a 10.50 car n/a, and in the 9's on n2o.

I have a question, How do you go about cutting the springs exactly?? I heard a wiz wheel and use some water right afterwards so u don't ruin the spring?

If anyone has a right up that would be great because I want to cut a coil on my rear springs.

Thanks.

You can cut it with a wiz wheel or a cutoff saw. Just don't use a tourch, thats what ruins them.

Actualy, it was way loose. Recomended for nitrous use is something like .007x bore diameter. So it should have been .028-.030. It was 3x that. Which is why I was getting alot of blow by.



Combo was a R302 based 352", 3.4 stroke, 4.060 bore, JE pistons, AFR205's, TFS R lower, Hogans upper, lil comp 272hr hyd. roller, and about 10-1compression. That backed up by a lentech 4R70 with a tight-ish converter, lockup and transbrake. When it goes back together it will have a bigger hyd. cam, and a 4.100 bore.
