And my LCAs made the NVH go up like crazy, I can't even hear my Dronemasters.
As I've also said over and over - start with the basics:
1) WHAT ARE THE FENDER HEIGHTS?
2) What are the rims, tires, and tire pressure?
In your case, let's assume that your tires and rims stayed the same. Then,
correctly putting on the POS B springs (even with new isolators) should result in a front fender height of ~25".
If that's not the case (with correct rims and tires), then you likely didn't tighten the FCAs and/or
LCA when they were
under FULL load. And, IMHO, that's one of the MANY issues in reading the
BS results of people installing springs on their car.
Not using isolators will often add a lot to NVH. It varies a LOT! IMHO, it's a very bad idea for many reasons. For the top, it puts a point load on the K-frame, frame, spring. On the top & bottom, you get "metal/electron/etc migration" between the two different metals - and water/moisture greatly speed up that process. It also put a lot more stress on the ends of the springs - and as you saw, after 10+ years, the ends of the springs can break.
It's not very hard to change a Stang's
suspension. The issue is the TON of incorrect, poor, BS info out there. It was like that many years ago. It got better for a while. And, it's gotten much worse in the past years.
The other HUGE issue is tolerances and how they vary from one POS Stang to another. Also, if the fender has ever been removed, then the opening will very likely be a little forward, back, and maybe high/low. That all adds into "what tires will fit".
I'm sorry you got misinformed. I had that same problem many many years ago.
Good Luck!
