Looks pretty easy to me, I'm surprised they are quoting as much time as they do, maybe just for newbie wrench turners.

 

One inch lower new springs, and 4 shocks, and rear bar from CDC for $350.

 

Not the right parts for what the OP is looking to do.

The CDC $350 kit has struts/shocks and a rear sway bar, no springs.

OP is looking at springs and a adjustable panhard bar.

 

Why would one need a PH bar if the rear is still centered? Is there any noticeable performance gain?

 

It has a fixed length panhard bar from the factory.

When you lower the car it pulls the rearend off center so you need an adjustable bar so you can center it again.

 

Wasn't saying it was hard, just saying it wasn't worth the amount of time and work when somebody else will do it for $50.

 

I'm too cheap to pay someone to do that stuff that I can do myself I guess.

 

I got the Steeda PHB and brace for $125 off eBay. If the '11 brace is like the '10 and prior, it is a flimsy POS. Simple install.

I had a UMI PHB before with the roto-end and it was terribly noisy.

 

Only if you want the car to go down the road in a straight line (watch a Nascar race one day and look at how the cars crab down the track. This is on purpose for their left turing ways. They call it a track bar...Southern for Panhard)... Some people don't care.
my 1" drop resulted in the Rear shifting quite a bit. An adjustable bar alllowed a perfect alignment.

 

Actually it does or did have springs and they were free.

You don't need a adjustable panhard bar for a 1 inch drop..1.25 and above yes

 

Oh? I and several others here would argue that. If you don't care that it could be off by 1/4-1/2 inch then no, you don't...

 

What he should do is lower the car first, measure the rear axle shift, and then decide if he wants the panhard bar. I've heard of members on here whose stock car's axle was shifted, and lowering brought the rear end into alignment.

 

There's no doubt you need to measure. I'd like to think the cars are built straight, but that, in fact, may not be the case.. Measuring to the bodywork may not be accurate as a result. An accurate centerline reference, or a Laser set-up would really be the only "true" way to get it perfect.

 

Actually my rear must have been off center to the right because it's exactly centered after my mild drop....go figure. I was wondering if there would be any noticeable improvement in handling by replacing the stock one for an aftermarket unit.

 

Times two or three or four. For crying out loud guys. Don't waste your money if you don't need to.
I didn't need it with the Steeda sports. And the OP does not need a stiffer panhard for tracking either. So, lower first and see. Even if it is off slightly car will not go down the road sideways, nor will it affect the front alignment. Lots of Shelbies come from the factory with the rear off-set.

Most after-market springs should fit the 5.0 (the Steedas did) but the front struts and shocks won't. In this case, you will have to replace the front strut mounts with 2010 or older ones from Ford. After-market hasn't caught up to the new car yet.

Cheers.

 

But is it easier to install the adjustable panhard bar while the springs are up and being installed anyway?

 

1.0 inch drop can be measured as off track by about 1/4 inch out on the drivers side. Visually you can't see that difference...I added Eibach pro kit with sway bars and a Steeda adj. pan hard bar to my 2010, and with factory rubber i couldn't see the difference. When i added fatter tires on the back the rear was out about an inch more on the drivers side, It was visibly noticeable!! I got under the car and made the adjustment.

 

As measured on your car. Agreed. Also agree that wider tires will acerbate any differences. Remember that the Eibachs will lower the car more than the Steedas and thus acerbate (can I use that word again?) the problem.

Maybe that's why it shows up more on the Shelby. Wider tires.
My car looks fine from the rear and so I am not going to measure it.

Cheers.

 

That's the spirit....Ignorance is bliss!....
