To make a long story short, after 200k miles I am replacing the front end components on my 70 XR7, 351W auto, no air, ps, pb.

Out of the showroom, I thought the car drove fine for me. Today, I would say it is a little soft. I am not certain if it is the age of the springs or a change in my driving style.

In any event, I am seeking opinions on whether to go with the stock spring or perhaps use the variable rate springs now being offered. I certainly want to increase my handling characteristics, and was wondering if the variable is the way to go, or should I just go with a stiffer spring?

Except for mfrs hype, I haven't heard of any installations with the variable rate spring, and would appreciate comments.

I haven't heard of variable rate springs other than rear coils for passenger cars. If using modified springs, they stiffen as compressed.

Any modification that is normally done to the early MUSTANG can be done to the COUGAR as both use the spring over the upper control arm design giving more negative camber on hard cornering. The SHELBY drop and a host of other things can be done, such as modifying the steering box for a quicker ratio, etc.

-GLOBAL WEST- will give you some ideas. Just be sure the aprons are in good condition, sub-frame connectors and an export bar are recommended. There is a specialty spring compressor used (safety) for this type of spring design.

I am looking for information concerning factory performance/aftermarket speed parts (1958/1960) used on the MEL (Mercury-Edsel-Lincoln) (Also Thunderbird 59/60) Engine Series (383-410-430-462) produced from 1958 thru 1968.

Also older FORD Special Service Tools

You might want to try a larger diameter front sway bar and adding one to the rear. This along with some good shock would keep the car from feeling like a boat. I added a rear sway bar and some KYB shocks and was amazed at what a difference in my fastback Mustang with a 390 in it.
