So I had some 12 inch 88 springs on the front of my 1987 GT and found it to be to low. I got tired of it.
I just changed from the 12" used 88 (ARD) springs to a pair of new Mogg # 6556 13.75"

...so this is almost a 2" difference...but the car looks like it was raised 4 to 5 inches.
I just drove the car a little bit, and they ether are not fully settled...or that just is how it is?

Can new springs really accommodate for that much lift?

wait... I think it just looks like more than it is.

So I had about 2 maybe 3 inches of space in the wheelwell with my 12 inch springs, now I just measured 5 inches.
maybe I will drop 1 inch with settling. Or maybe I'll cut one coil of the new springs later down the road.

lol. but WOW it just looks like a LOT of space now.

Keep in mind that 1" difference at the coils becomes about 1.5" (I forget the exact ratio) at the wheels. It's not 1 to 1.

And that's not even taking into consideration that the new springs might be stiffer than the replaced ones.


Did you get the springs positioned correctly so that the end of the coils sat in the little "pocket" of the lower control arms? If not, that would add to the height as well.

Agreed. It can be a bit of trial and error to find the right one.

When I needed to replace my GT's springs I used '87 Chevette springs (see RockAuto)

Raybestos lists different sets of front springs for Chevette.

I believe so. Possibly not. I was more focused on aligning the end of the top coil to the exact position to the upper spring bushing that was stuck to the bump stop post. It was ether get it to align or remove the rubber altogether. Thinking now I wish i had removed it.

IIRC the bottom coil I remember was facing to the inside of the car because I was prying on it to get the springs to fit in.
