We put new 4 leaf, leaf spring, shackles, ubolts, shockson the rear of our 68 Fastback and it still sits low and rubs the tires. They are 235-60's on a 7 inch wheel with a 4 inch back spacing. I cant have anyone in the back seat or they rub. It still sits higher in the front than the back, actually you cant tell a difference between the old springs and new. I dont wanna use air shocks. Air ride technologies setup is over 1500 bucks. Any suggestions?[:@]

 

standard, mid or reverse eye?
what's in the front?

where do you live?

I'm having the same problem. I have not done anything about it yet. I dread the bumps!

I just went through the same grief with my '67 Coupe. I bought new "stock" leaf springs, only to find out they made zero change to the ride height.

To get it the way I wanted it, I had to replace the front coils with 620 lb, 1" lower springs. Then I took the old set of leafs to a spring shop and had them re-arced +1.5". If I could do it again, I might have gone even more, maybe 1.75 or 2".

I have the same issues with my '66 coupe. I have not changed the leaf springs yet tho' but that is on the to-do list.
My front sits good, but I was wondering if the 1 1/2"' raised springs would do the same ting instead of buying stock then having them re arched. My rear tires are also 235/60 and I have CREAGERS all the way around.

 

I don't think I would have leafs re-arched, because the replacement ones are so inexpensive to begin with. I put 5-Leaf Mid-Eyes on mine for under $200. They were a pretty good match to my 620's that were cut to lower further. My wheels sit out on the fenders in the front and back, but the 5-Leafs are so strong I don't bottom out on bumps. I am surprised that stock springs didn't raise the back end if the original ones were sagging. That makes no sense.

 

We were not happy the it didnt change anything what is the advantage of putting a mid, lower, or upper eyed spring on one?
