Longevity modifications???

[Holly]

I have a '87 5.0 and it has an automatic transmission. It also a few hundred thousand miles to 200K. Pretty much everything on it is stock. It is a "parental hand-me-down car."

I've been reading about modifying the performance and making it faster and more powerful, but I also have my car's longevity in mind. I don't want to make the wrong modifications in the wrong order that would actually hurt my car than enhance it.

After reading up on mustang modifications, I basically have a few things in mind that I want to do first. 1. Remove air-silencer and put in a K&N. 2. Performance alignment. 3. Subframe connectors. 4. New brake lines, fluid etc. 5. Strut tower brace and G load brace.

I also want to put in new spring, struts, and shocks as one package. I just tuned up my car and have noticed a better quality ride. I want to do more, but like I said, I want to modify the car so that it improves my car's performance as well as longevity. Restoration is pretty much the issue at hand.

I would greatly appretiate any input or advice on modifications that would improve this "old mustang with a bunch of miles on it" performance, as well as longevity. Thanks.
