It is bad up there as well, but at least they are fixing it, unlike down here

 

I'm down here in NO now- you're right, man. Seems like every parking lot entrance is 3" above the road and no two slabs of pavement are aligned. Wish we could have Atlanta quality roads!!

 

The roads down here are just a hot mess. They seriously make Baby Jesus cry.

 

I like Ground Control..

Steeda has a good kit as well. You can get custom length Eibach Springs as well as spring rate...

Stinger,

Is 1.5" drop OK for street? I'm not sure if it is because of the Roush front end but you car seems lower than other Mustangs I seen with the same drop. The Mustang is so high from the ground that a 1.5" drop is consider moderate by Eibach, H&R Springs and others. I seem to agree but want the opinion of people that have done it.

 

I might just go with the mild roush springs. I dont plan on dragging it,or tracking it, so I'm not too worried about not being able to pull a G on the skidpad.

 

This setup sounds pretty hardcore...so pretty much perfect.

I haven't been around here that long... but long enough to know that Stinger is worth listening to.

 

While I agree, I've taken the impression that he's sponsored on some of the parts on his car, so it makes a difference for someone who is neither competing on a regular basis nor gets the parts for free/cheap. Please note- I am not at all attempting to dismiss Shaun in any way/shape/form; just stating that if it's between spending $1600 for a complete suspension swap or driving with a slightly unideal ride until I can swing new struts and shocks... I'll take with the unideal ride. It appears new struts/shocks all around are ~$400-500, which isn't bad, but I'm nervous to spend that much on top of the springs and install and risk not liking the height for actual every day driving on Louisiana roads. We'll see what happens, but I'm thinking I'm going to throw the springs on the car and drive it for a while with the adjusted height before I decide to go all in and match the rest of the components to the new height. It's quite possible I'll decide it's simply too low and go back to stock springs.

I do appreciate all the input and again, Shaun, I meant no offense in what I said.

 

No problem Freshmeat.

I do want to address some points from your post.

I know that I am given special treatment by some companies, some parts are discounted, some are given to me etc.
However when I accept something from a vender I make it CLEAR AS DAY to them that I will post my true opinion of their product or service and am not shy about speaking my mind. Part of how I get the hookups I do is by remaining impartial and a true 3rd party. That way I can say to part maker "X" hey let me try your part on and I will post independent dyno results to back up or disprove your claims (I have actually had a venderback out when I said I would be doing before and after dyno pulls to prove their merit LOL)


now onto the topic of the thread.

I DO NOT RECOMEND THE 1.5" DROP SPRING FOR ANY STREET CAR PERIOD. THEY ARE BEING SWAPPED OUT OF MY CAR NEXT WEEK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The FRPP 1" drop spring is in my experience the best spring for the S-197 for both a street car or an open track car.

You can change just the springs, its safe to change springs without shocks. HOWEVER I feel its a bad idea. The factory dampers were designed for use in conjunction with a spring of a certain spring rate. when you DRASTICALY change that spring rate that’s OEM shocks ability to control that spring is greatly reduced. With MI roads as crappy as they are and the unknown (something in the road you need to swerve and say there is a bump in the road) I have never and will never put an aggressive spring on an OEM shock.

IF YOU LOWER THE CAR EVEN 1" YOU MUST PUT AN ADJUSTABLE PANHARD BAR ON THE CAR PERIOD!!!!!!!
The panhard bar's job is to locate the axle left to right in relation to the body/chassis.

When you lower the car you change the angle of the Panhard bar and that causes the axle to shift to one side.

 

Thanks very much for your input. I honestly hadn't thought about the Panhard bar, which is insane given my experience with off-roading (we loosely call it a track bar in most instances.) I simply hadn't thought of applying the same basic thought process to going down as I do going up.

I already have the 1.5" springs sitting at my Mustang shop. I'll see how I like it, since they're already paid for. If I don't like the height I'll either go back to stock or I'm going to swap to the 1" coils and order new dampers to match.

There are actually a few guys around here who have 2" drops on their Mustangs. I don't know how they don't drag it on EVERYTHING in existence.

Again, thanks for your input. It always helps to have a more rounded understanding of what I'm getting into, even if it's after I bought parts.

 

Interesting you're not liking the springs. Is it the spring rate? Or are they just too low...because your car looks suction-cupped to the track! Hahaha

 

In all honesty, if I don't like the ride of the 1.5" springs I'll very likely go back to stock and see what Air Ride Technologies puts out. I've seen their kits on lots of classic cars and it's always been just right.

 

The 1" and 1.5" are the same spring rate.
On the street the far is too low
On the track I was bounding over a curb and it scraped the bottom of the splitter and hit the bump stop too easy (need more travel)

The 1.5 look killer just not pratical

 

I don't have a gt but I am lowered 2" in back and 1" in front on tein s-tech springs/stock shocks/struts using a massive adj spherical endlink phb with relocation centering bracket cut rear bump stops current setup on my 2011 3.7.
I can tell you after getting back from a trip to hilton head with my wife the car rides great to both of us, especially when compared to my 2006 which was lowered on H&R coilovers 245/35/20 tires on 8.5" wheels
or my 2010 which was lowered with the same setup as my 2011 except the 2010 was on 265/35/20 mounted on a 8.5" wheel and my 11 is on 245/45/20 on a 8.5" wheel so either they did a much better job stiffening up the 2011's from the factory or the 45 series tire sidewall makes the ride a lot smoother? Speed bumps and getting in and out of parking decks/lots is not an issue either and **** does it look good imo anyways slammed

fyi the 245/45/20 size is stock 20" size for chargers/challengers and 300's about 1" bigger overall dia than stock coming in at 28.1" when mounted on my wheels with my stock 225/60/17 bfgs measuring right at 27" overall dia

 

I like your car a lot. What is your ground clearance if you don't mind?

 

Gotcha. I figured it was just too low. From the pics of your track day, you couldn't see ANY daylight under your car! What is the diameter of your slicks? They look shorter than the 19" street tires, no?

 

Since the car is only 1" lower in front and the tires are 1" larger in dia its about the same as stock ride height I think about 5" on a level surface give or take, I'm thinking of doing a chin spoiler if/when some brilliant company finally decides to release one for the v6 models I hear RTR is supposed to have one out by the fall have to see what that looks like

 

Hi Shaun,
I'm planing very soon to get me a '11 GT Brembo. In one of your posts, I readed that you got a '11 Premium (leather GT). Do you see any advantage of going for leather seats VS cloth seats, regarding that the seats keep you planted firmly in the cockpit during high-G cornering?, also since I'm planing to lower my car with 1" springs with better shocks, which adjustable panhard bar do you recommend?, I also saw that you got a 3.73 gear, Do you see any advantage of this one VS a 3.55 or a 3.31 for tracking purpose?

 

I would love to drop just the rear about .75" to even things up. Did this on my 05 with Roush rear only springs. Not sure how to proceed on my 11 Brembo to achieve the same.
