Rear Suspension Refresher

[ViciousBlack97]

So I finally got around to re-doing the rear suspension on the Cobra. Maximum Motorsports heavy duty lowers, stock replacement uppers, and new differential bushings. All I can say is wow. The car feels so much more planted on the road now, and acceleration is infinitely smoother. If you guys have any questions on the install, feel free to ask. Oh, and as a PSA, if your car came from anywhere salty, go ahead and get new control arm bolts. They're a very particular size, and if yours are as rusted as mine were, they'll need replacing. As for a small informational bit, the 94-98 Mustangs have different control arm bushing bolt sizes than the 99-04s. Go figure, huh?

Definitely does help to do that on an old car. I went with the nuclear option and swapped an IRS with a FTBR kit.

You've got that right. The rear end feels absolutely rock solid now. And I've thought about an IRS swap, but for the power goals I have in mind for this car, beefing up the IRS would get pricey very quickly haha.

Not anymore expensive than beefing up a SRA. I did the math. Not arguing for or against each one, its personal preference really and the stick axle is always gonna be better for a 1/4 mile car.

I have MM lowers and UPR Double Adjustable uppers with new bushings and I didn't really notice that much of a difference. Knowing what I know now I should have just replaced the uppers with an OE style, but I got a great deal on the UPR's.

Are the UPR arms the Pro or Extreme series? If so, it will allow for the proper movement.

Did you set your pinion angle when you installed the upper arms?

They are the Pro Series. I set the arms to stock length as I don't have an angle finder.

I did tubular on all four with new rubber axle bushings and poly spring rubbers and a new edge rear end. Rides nice.

 

[ViciousBlack97]

That's one of the most dramatic changes, the car just feels smoother going down the road now.

I did pretty much the same thing as you op, but I also change out the springs and shocks at the same time. Your right it was a world of difference in driving comfort and alot of noise that was coming from back there was amazing to me, all gone when I did the swap out.

Yeah, I just got the quad shocks in the mail yesterday and put them on. It's crazy how much, I guess tighter would be the appropriate word, it feels.

With the new control arms, bushings, and shocks, I did not need the quad shocks. With that it gives me more room for the wider tires I will be putting on when $$ becomes available.

See, I've heard examples from people who were fine without them and people who experienced awful wheel hop, so I just went with keeping them. Besides, when I put some 315 rears on, if it's too close I'll just flip the shocks around.

I need to start planning for a refresher on the rear as well.
Question:
Which Quad shocks did you go with? I haven't looked at all the options available but last time I looked on Summit, options seemed really limited.

Maximum Motorsports sell Bilstein quads, but they also claim you dont need quads if you install aftermarket arms (in most cases).

BTW if you decide for some reason to go with aftermarket rear UCAs.. Keep rubber bushings on the part of the control arm that connects to the rear. Otherwise using poly you end up creating unnecessary binding.

Also to fit wider tires, if you want to keep the quad shocks just flip them. That will help. Otherwise put on better LCAs and get rid of them. Coils helps too lol.

If you search Gabriel 14039 you'll find them. They're listed as a steering stabilizer, but they look identical to the factory quad shock. And they're only 33 bucks a side on Amazon. For something like those, I wouldn't splurge on Bilsteins or KYBs.
