Do lowered mustangs just feel like crap over bad roads?

[Metz3020827]

I am starting to wonder if my coilovers are just tired after having 55k miles.

I have continental extreme contact sports up front (275/35r19) and nitto g2 555s over the rear. 305/35r19.

the fronts are like 15 months old; and the rears are 2 months old.

Arizona roads are kind of shit and when I drive over them, it’s pretty rough; especially if going fast/switching lanes.

is there anything in particular that can make the car feel like this? I need a few adjustments in alignment, and I have quite a bit of negative rear camber.

it’s tiring having to hold onto the steering wheel with a death grip.

living in Louisiana with a mach 1 HP, which is a factory lowered mustang with stiffer suspension...yeah, rough roads feel like shit. I mean, rattle the fillings out kind of shit. it is only slightly better with comfort setting on the magnaride, but marginally. comparativelly. my 86 stock bronco rides like a boat over glass same roads.

Do the cracks pull it all over the road? Our roads here suck.

You're 20k late on a rebuild. And if you're using FA preload defaults you have basically no travel.

FA stiffs everyone a good 1.5" of travel. I have no good answer why the refuse to admit it, and fix it.

Makes sense. I’m about to pull the FA off and replace with steeda stuff. And sell the FA.

well, the M1 HP tramlines like CRAZY, at least with factory settings and the Cup 2 tires. I need to order my PS4s soon, and will also get the front camber leveled out somewhat from factory setup.

Yeah I heard those cup 2s are notorious for tramlining. I think my tires do the same thing.

275 shouldn't be giving you fits. But if you haven't checked your toe, I'd get on that.

Toe is hardly off in the front. It’s a little off but not enough to make that big of a difference.

I want to clarify, for my post. your Q was about how rough the ride, and while I have tramlining issues due to ford settings and tires (I don't hate it, the car as built is a fucking beast for handling, just nor comfortable), the lowered suspension, low pro tires, even with fords tuning is a very rough ride on uneven pavement, cracks, adjustments, etc. I have had some insanely jarring experiences on roads and transitions that in my wifes 4runner or my bronco or any other vehicles I never even noticed. and yet it gives a major shock in the stang.

That's a lot of rear camber.

Yeah I know. Every shop I’ve been to says they can’t adjust it at all.

 

[GrabberBargeCaptain]

I mean at 55k miles yes they're due for a rebuild. Some get a bit more some get a bit less but 55k is not unreasonable for coilovers

Which ones are they and what are the spring rates, and how low do you have them set?

 

[Paul McWhiskey]

I could be wrong, as I am not completely up on the Mach 1’s, but rear toe should be adjustable. Not to be hypercritical, but your shop should be able to do better on front and rear toe. Which could effect rear camber.

You might school the shop you are using, or seek out one that has a better understanding ( or possibly a desire to do better work and please the customer ) of Mustang suspension.
