Are these the rears from Roush everyone is using? http://www.roushperformance.com/part...2005-2012.html
I would like to level my 05 GT out too.

 

Best I can tell, your wheels are 18 x 8.5", which really limits your tire size to 255/45.

I also note that your car is a 2006 . . . about 7 years old and how many miles on the shocks and struts? You might not have to replace those right away, but I'd keep them in mind and do them before getting involved with any further mods.

It has 77k miles on it. I asked my mechanic and he said they should not need replacing and should be fine.

What does Ford say?

 

I've never put that many miles on OE shocks without it being pretty obvious that they were not just well past their prime, but ready for retirement. And that's with original springs rather than firmer aftermarket replacements that'll beat the shocks/struts up more.

The Scheduled Maintenance Guide for 2008 recommends "Check shocks and struts . . . for leaks and damage" as part of the service at every 7500 miles. Nothing I found mentions either a specified replacement mileage or a check of their damping. But Monroe's 50,000 mile replacement recommendation is well advised, and certainly so in the presence of ABS (a wheel that's bouncing more than it should because its shock is getting tired can and will trigger ABS at too low a level and needlessly increase your stopping distance).

Those are the ones I used. #401295

 

If you put taller tires on it, you'll mess up the speedometer, and it can jack around with the abs and traction control. I wouldn't go that route.

Here's my car on UPR/Eibach Pro springs. (same specs as FRPP K)

 

I really like the way it looks and I want to lower it but I don't want to spend all the money to upgrade struts/shocks and other things, and that would be the best thing to do.

I don't want to mess it up doing it myself either.

I think I'm going to just do the rear, and hope nothing goes wrong.

As far as the adjustable panhard bar, I'm pretty sure somethings off with my rear end anyway as I notice a slight difference back there with the tires. I will have to take pics to show you guys.

 

Take Norm's advise he knows suspension. I just lowered my rear 1 1/2" but my pony
has 15,000 miles. The reason to lower is to correct the roll center as these cars stock
will float and fishtail. You will need an adj. panhard as I needed to re-center my body
1/2" to the drivers side. Brackets are also needed for grip.

 

Ok so I'm ordering the Roush rear springs to level out the car. That's all I'm going to do for now. Maybe an adjustable panhard bar, as it seems my rear is slightly off already. I'll see how it goes after the spring install.

Does anyone know of a good install video/instructions for the rear springs?

Thanks!

 

This adjustable panhard bar works well. (it's what I'm running on my car)
