machinehead Posted October 12, 2009 Report Share Posted October 12, 2009 Considering lowering my GT500, mainly for appearance. Don't intend to track the car and really don't push the limits on the streets. I would like to tighten it up though. I drove two Roush cars, a 2009 and a 2010 before I bought the GT500 and the suspension seemed "tighter". Not that they rode any harsher than the GT but they made less noise, less banging. Local speed shop is recommending Eibach Pro-Kit Lowering Springs. Said I can keep the same shocks and MAY not require an alignment. Wouldn't have to worry about the panhard bar, upper and lower control arms, etc... OK guys - educate me. Tell me why I should or should not go this route. Remember I'm not racin' the car and want to keep the ride somewhat civil. I know there's a bunch of threads regarding suspesion upgrades and lowering and I've read them, but there seems to be a number of different approaches (i.e. lowering springs, ford racing, coil overs, etc.) Just wanted some opinions on the Eibachs.

2nd2none Posted October 13, 2009 Report Share Posted October 13, 2009 I'm by no means a professional in this dept but I would definately get an alignment after modifying a suspension. Also, from reading other threads on here if you lower the car and dont get the adjustable panhard bar the rear axle may not be exactly centered anymore Link to comment Share on other sites More sharing options...
08 Mustang Posted October 13, 2009 Report Share Posted October 13, 2009 I installed the Eibach Pro-Kit lowering springs on my 2008 GT500 and couldn't be any happier with it. I am still using the stock struts and shocks (will replace later down the road), I did go ahead and install a set of camber bolts (everyone was 50/50 on these), I did get an alignment when I was finished (definitely recommend!) and I did need an adjustable pan-hard bar (was needed). Hope that helps alittle.. Good Luck! before after Link to comment Share on other sites More sharing options...
Aussie67 Posted October 13, 2009 Report Share Posted October 13, 2009 +1 Prop kit is perfect. Still a good ride but not extremely harsh, solid on the road, good handling, looks greaat. I would advise checking alignment and you will definitely require an adjustable panhard bar. I would also recommend checking dif pinion alignment after lowering to ensure you are still within spec. Pull the trigger and enjoy. Link to comment Share on other sites More sharing options...
SVTpower Posted October 13, 2009 Report Share Posted October 13, 2009 you have a coupe or convert..?? For a convert, get the Steeda kit which off a different spring kit vs. the coupe.........several photos I've seen of the 'coupe' kits makes the convert sit too low in the rear. For the coupe, I personally like the FRPP kit. Link to comment Share on other sites More sharing options...
dukenrock Posted October 13, 2009 Report Share Posted October 13, 2009 I installed the Eibach Pro with the Tokico struts and Watts Link. It's a nice set up. Link to comment Share on other sites More sharing options...

machinehead Posted October 13, 2009 Author Report Share Posted October 13, 2009 Thanks all. Sounds like an alignment and adj. panhard are in order whatever the lowering method. Link to comment Share on other sites More sharing options...
STILLEN Posted October 13, 2009 Report Share Posted October 13, 2009 Thanks all. Sounds like an alignment and adj. panhard are in order whatever the lowering method. An adjustable panhard bar is definitely needed, as are the alignment bolts (and alignment). With the pro kit springs, the panhard bar needs to be shorter (about 1 inch if i remember correctly) than stock. If you can, I recommend changing the shocks while it's apart to avoid paying double labor. The lower springs will kill the stock shocks pretty quickly.

Just the type of feedback I was hoping for. So if I brought my car to you (hypothetically since I'm in PA and you're in Cali I think) you would recommend the lowering springs, shocks, adj panhard, alignment bolts and alignment? Do you know if the ford racing kit includes all of this except the panhard? I can do some research on my own but REALLY appreciate the opinion of someone who knows. Thanks again.

So if I brought my car to you (hypothetically since I'm in PA and you're in Cali I think) you would recommend the lowering springs, shocks, adj panhard, alignment bolts and alignment? Short answer...yes. But the actual parts I recommend depends on your intended use of the car. Do you know if the ford racing kit includes all of this except the panhard? I can do some research on my own but REALLY appreciate the opinion of someone who knows. Thanks again. Yes, the Ford Racing kit includes springs, shocks, front/rear sway bars, and strut tower brace. Everything fits 07-10, but the strut tower brace only shows 07-09 GT500 for fitment. So you still need an adjustable panhard bar for proper installation. It's essentially the same thing as Eibach's "Pro System Plus". It's part number 35115.680 Eibach GT500 suspension Dan Link to comment Share on other sites More sharing options...
machinehead Posted October 14, 2009 Author Report Share Posted October 14, 2009 Short answer...yes. But the actual parts I recommend depends on your intended use of the car. Thanks man! Main reason is to lower the car for appearance. Don't want it radically lower/slammed. Just want the tires to fit the wheel wells and get rid of the "jacked up" look. No intention of tracking the car. I do want the handling to be crisp and tight. I would really appreciate your thoughts on this. Link to comment Share on other sites More sharing options...
