Best ifs kit? rms, hdk, gt suspension, or magnum force?
Awesome break down. Either way you go is gonna cost some coin.
I still feel like the stock style steering Box with pitman arm, drag link, idler arm, inner and outer tie rod ends are going to feel less precise then a steering rack with only end link. There is also the longevity aspect. With more moving joints the stock system is going to loosen up and have more "slop" then the rack will. I had my car set up with the best of the best stock upgraded stock style suspension and it was a big improvement over the old worn out stuff but still not even close to how tight,precise and confidence inspiring as my new HDk setup. I know everyone has there own opinions but I literally did both systems to the extreme and I have found myself wondering why I didn't make the switch so much sooner.
Then there are the other benefits:
Outstanding header clearance
Easy to find replacement parts. The mustang II front suspension is the single most used system in the aftermarket.
Oil pan choices are endless
The added room makes a big block dart easy to work with and maintain
