I am happy with the factory stuff with a few mods. Like Shelby drop and Borgeson or R&P and a 1” sway bar. Progressive springs.

There are two different suspensions I have seen described as coilovers. The one like NOS has, which is technically a coilover shock that replaces the existing spring with a lighter rate spring but does not change the suspension geometry by replacing the spindle. The other replaces the entire upper control arm and spindle with a more modern mcpherson strut type assembly.  My opinion is the mcpherson type setup might be worthwhile to improve geometry while the simple coilover shock is just a different spring

I have a friend that professionally builds street rods. He does not like to use coilover shocks because he says the lighter springs invariably sag unevenly.  I would tend to agree with that. A lighter spring will be under more stress. But, I have no data to back up either argument.  Listen to those who have direct experience, like NOS or others that have it on their car.  But, I remember trying to sit on the NOSmobile fender to get a feel for what the ride in his car might be like.  The suspension did not move at all. He said it had adjustability so it could be tuned. That part I like, but a rock-like ride would not be tolerated.

Like i said…opinion. .

MS…last year when I stopped at your place, I still had the the lower attachment point 1” outboard (closer to upper ball joint).  I have the 350# springs for small block setup.  I had the shocks Compression and Rebound at very low settings (2 and 7 respectively) and the ride was harsh on smooth roads.  At the same time, with the very low settings, I did not like the bigger bumps at all.

The ‘65 still uses stock style suspension…upper, lower, and strut rod.
Upper:  Arning drop 1”, MS grease groove, offset shafts
Lower:  Energy Suspension inner pivot bushing
Strut rods:  Poly bushings
Sway bar:  1-1/8” Front sway bar (90’s vintage Mustang Plus)

A couple of days later, Coupedaddy and I moved it back to the stock location on upper control arm.
I readjusted the shocks back to 5 Compression and 10 Rebound…in less than 30 minutes at a leisurely pace.  We had the kindness of Steve and Glen to use their lift.

2021 Rockwall Bash:  5 compression/ 10 rebound
2021 Kansas mini Bash:  7 compression/ 12 rebound
2022 U.P. to Texas (relocated 1” outboard):  started at 7/12…2/7…too much spring
2022 Texas to Vandalia Bash (stock location):  5 compression/ 10 rebound
2023 Bash:  5 compression/ 10 rebound  most likely

It only takes a couple of minutes to change shock settings.

I vote yes on the "improved" stock set-up and spend the bucks of 'go-fast stuff'.....ignition...cam...heads...exhaust.

That's not your normal answer Sal... oh wait...nevermind.

Sal did say the magic word, CAM 😆

I've riden in NOS681's car, and in my opinion it is the best ride of any Mustang I've been in. A close second is Bullet Bob's nearly stock 66.

I have DRIVEN Nos' car and I thought it was very nice and supple, if that can be applied to a car's suspension, yet solid.  It felt great, especially compared to the Heap which has Mustang Plus 620's in the front.  Yes, I was impressed.
