First round of IRS mods

[texasboy21]

With 13,500 miles on my 17 GT PP I have decided to start doing some chassis, IRS, and suspension mods.

I am starting with Michelin Pilot Sport 4s tires (stock PP sizes) and the Steeda rear subframe alignment kit and busing support kit.

I am hoping this combo will reduce the amount of wheel hop and stabilize the rear end. I plan on adding the Steeda rear braces as well.

Regarding the suspension mods, like most of the PP cars, my suspension has become bouncy. Overall the car does not feel as tight and stable as it did while new so the research process has begun.

I would appreciate any tips, suggestions, or feedback. :cheers: :ford:

I've added wider tires and that feeling of the rear end being disconnected seems more pronounced to me. I've been looking at the Steeda stop the hop starter kit which should help. Once they have a sale I'll probably be buying.

I friend of mine is starting his mod journey and tracks his car like me. He installed ONLY the Steeda rear IRS brace and front IRS brace and constantly raves about the change, stating he felt the rear actually was part of the car. He does time trial racing on a basically stock suspension and is quick. He's a good driver. In fact, he's replicating my suspension soon for the most part and at that point he's going to destroy me... haha.

I have both BMR and Steeda products on my car but the BMR CB005 should be your choice to stop cradle movement.

For the bouncy ride pick what spring you like and use steeda's fixed or adjustable pro-action struts/shocks with their billet rear shock mounts. I have BMR SP080 springs with steeda's fixed dampeners and steeda's billet mounts. ALL the bounce is gone and handling is greatly improved.

It was a toss up between the Steeda and BMR cradle solution, and I believe both get the job done well, but a local guy had the Steeda parts available for an incredible deal.

Hi there

I have 8000 kilometres on my Australian RHD pony. I have installed the BMR Cradle lock out kit and BMR Vertical links. The car is much more planted in the rear end. Cannot speak more highly of the improvement in the car stability. The BMR products are really very very good.

I'm not a technical person and so the next bit has taken quite a bit of research - because from here some of the modifications that you might choose to make will generate additional Noise/Vibration/Harshness (ride quality) - the dreaded 'increase in NVH'. Some of those things (basically) are where you are replacing bushings in the IRS that are rubber with harder compound (teflon etc) bushings and so there is less play and soaking up potential vibration etc. So at this point you have a choice about what is important to you (I think) between progressively more impressive road handling or ride quality (comfort).

Next up is coilovers - in my case Vogtland coilovers to lower the car by an inch all round. At the same time I will have installed camber plates for the front and camber arms for the rear together with whiteline swaybars and end-links.

Last up (yet to purchase) are new spherical bearings, adjustable toe links and Ford Racing Toe Rod bearings. I think that this should give me the kind of feel I am looking for from the car - and how the car should have come from the factory.

Good luck on the journey

Front IRS Brace?

I have the new tires and Steeda bits installed, and there is most definitely an improvement in traction.

I havnt pushed the car yet, but the rear end does feel much more stable. Overall I am pleased. Mods are fun! :headbonk: :cheers:

Front IRS Brace?

I think they go on the left passenger side.
