What ever drop GW Tells you to do is likely optimal for their arms.
If you are running the GW arms with the proper drop, IME that is the single biggest gain from one thing.
From my experience, the old mustangs like soft bump and stiff rebound.
The Bilsteins are the “cheapest” good shock. I like their sport version.
Viking makes reasonably priced double adjustable shocks that opentracker sells.
Hotchkis sells some trick Fox shocks that are pricey.
And if you have unlimited money you can get Penske shocks that Cobra Automotive sells.
For spirited street driving, I would go with the bilsteins. Better shocks are likely to cost way more.
Like several of us here, I don’t have a single rubber bushing in the suspension. While I’m not sure roller spring perches and strut rods make the car faster, it “feels” more supple and responsive.
In order of importance (with what I have personally done) I would rank mods in this order:
Shelby drop/tubular arms
Springs/sway bar/ shocks
Biggest sticky tires you can run
Rear springs with del alum bushings
Tubular lower arm with spherical bearing
OMG Jsams, I had NO idea there was an 'off the shelf' Fox shock available for our classic mustangs!! Thank you SO much for enlightening me, because as a SF Bay Area motocross and mountain bike guy I've still got a 'connection' to the Fox suspension that's been making everything bounce better since I was a kid mx racer!!
You NAILED my needs to a 'T'; monotube DIGRESSIVE valving! That means it can be firm cornering (slow piston speeds) but if you hit a sharp bump (faster piston speed), the shock valving 'knows' and softens up. It's the best of both worlds. Who's tried these, guys?? Somebody review these please...
Single adjustable valving from soft street to stiff race? Not clear if that single adjustment is rebound or compression or a little of BOTH? But I've got faith it's a damn good 'made in USA' product. All that for only $180 per shock? That's not pricey that's a bargain. Why isn't EVERYONE running those? In the past the Fox Shox company has been the kinda place you could bring your shock back to, and for a small fee they'd rebuild and/or revalve the shock to your liking if your needs didn't meet the range of production.
Pics attached below, dang link didn't work.
The only thing better, in my vivid imagination, would have been to have the shock body flipped upside-down, removing it's weight from the moving (unsprung) part of the suspension, and a reservoir, on a ss hose, at the top that can expand the oil/nitrogen capacity for even greater performance and valving adjustability. The only ones close would be $1,500 JRI, Penske, etc.
I'm all roller everything too. Roller spring perches etc., so this is my missing link. Wish they had heim instead of poly bushings but maybe that's ok... Thanks. Love to hear of ANYONE trying these?
