Need some direction

[SfSerge]

So looking for some direction from those with some suspension mods and bushing replacements. I just got a 15 GT with PP and its gonna be a street car 90% of the time with canyon carving and track days a few days out of the year. The car came with Steeda linear springs on the stock shocks. The plan based on mustang collectors reviews is that the combo of Steeda springs and Ford performance shocks was the best package. The real what next question is should I do alot of the bushings at once? is there a specific order so I'm not taking apart the same piece multiple times? what bushings are worth it and what can I skip? I was leaning towards the G brace, BMR cradle lockout kit, upgraded sway bar and diff bushing replacement. Any advice would be appreciated.

Dont mess with the bushings leave them stock instead get the stop the hop kit steeda pro action shocks and struts. i have them with steeda sport linears. My car is firm and planted and it handles like its on rails, i have no noises or vibrations. Of course with my auto I don't have to be as extreme as a manual car. I was gonna add sway bars but the car handles so good i wont need them.


Here is the list:

1) steeda pro action shocks and struts.
2) steeda sport linear springs.
3) steeda camber plates.
4) irs support braces.
5) steeda adj. toe links.
6) steeda vertical links.
7) steeda 2 point g track brace.

You and I are in the same boat! I got bored with my 8 second drag oriented S550 so I picked up another car to enjoy daily and occasionally track. After rigorously testing out every mod possible on our development cars, which are PP cars, I have a pretty cool plan for my PP.

I am going to use a combination of the OE PP rear monotube shocks and front GT350 Monotube shocks that can be had for $350. For springs, I am a linear spring fan....so I will be testing a new set of springs we are working on. For sway bars, I am going to stick to the stockers for a bit until I get a feel for what kind of bias I want from it, then will likely use and adjustable rear bar to fine tune.

For the fun stuff, making the IRS perform....I will be doing the following based on extensive experience.

CB005 cradle bushing lockout kit. This will remove most of the deflection within the rear IRS assembly. That layer of deflection causes many issues. Bouncy ride, unpredictable handling and acceleration and intense oscillation during heavy braking. This kit also positions the cradle in a more centered position compared to the factory set up. In my experience this is really all that is needed for most. I'm not personally a fan of adding too many components to achieve lesser cradle/subframe movement.

BK055 rear lower control arm bearing upgrade. This part is actually the very first part we started on when digging into this IRS system. The amount of deflection in this pivot point is staggering. Under load, the rubber bushing in this location enables the wheel/knuckle assembly to shift fore under acceleration and aft during braking, so much that you can actually experience tire to fender well clearance issues.

TCA045 vertical links. These are a must have for a handling application. The factory links are put through serious extension and compression forces...which leads to erratic knuckle movement that in turn causes inconsistent geometry. I am a fan of our dual bearing kit for a few reasons. The main reason is because the Delrin versions can often require disassembly to clean and regresse, to rid of NVH. I have yet to have anyone swap from bearing to Delrin, but I have people swap to the dual bearing every week.

FRPP knuckle bearings. TOE deflection is a bad thing when trying to achieve maximized performance from your S550 IRS system. These bearings eliminate the toe change that occurs when heavy loading the toe link in corners. This part should have been installed from the factory.

Those are the best few mods that will be kind on the ears in terms of NVH increasee and will provide you with the best improvements for your rear IRS system.

If wanted to take it further, you can grab the toe links and some differential mount solutions.....but they are not going to give you the kind of performance improvement that the parts above will, and often times the diff mount upgrades will cause nvh levels to be more than what you bargain for.

As expected I am bias to our brand, but any quality company you find that you think offers good parts for the money should work.

Happy Modding!
