Upgrading Suspension with either Roush performance single/triple coilvers or Ford performance M-FR3A-M8A.

[EddyB21]

if you have Rousch 3-way money you have money for actually good suspension be it Ohlins, RideTech or MCS. Rousch is just re-labeled KW. Blech. Ok, it's not hot garbage but you can do better.

great thanks for the reply. That's why I wanted to post on this forum to get experience from others

Hi Efi,
I haven't been to the track as of yet. Right now they are the stock PP1 package.

Just as a suggestion, and others that track their cars regularly will probably agree, but you should first start with learning the car on track as is and maybe doing some minor brake upgrades and better tires. Then when you feel like your skills have expanded so much that the stock suspension is holding you back is when you should upgrade it.

By all means, do what you want with your car but I would agree with others; if you want to get into the track life, start with brake pads and wheels/tires.

For reference: the stock PP1 equipment feels pretty good on the street but is a sloppy mess on track.
I have the Ford Track Pack - it feels amazing on the street. Stiff but not overbearing. I dare say perfect for street/canyon use. On the track, it's definitely an improvement but still undersprung. These cars are heavy and it takes a lot of spring rate to control the weight.

The Steeda Dual Rate springs at 350 lb/in are probably the best rates for a dual purpose car. Anything higher will be better for track but going to be less comfortable on the street. It's all a compromise as @NightmareMoon said.

Steeda Dual rates are too much spring for most over the counter shocks on the street, the daily ride was way to busy for my tastes. With like Ford, Konis or Steeda or Bilstein shocks, stick to the other handling springs from Ford, BMR, or Steedas non-dual rate springs (unless you have magnaride, in which case IDK).

on track the dual rates felt great paired with Koni adjustables on stiff settings. Street not so much.

if you’venever been on track before, you really shouldn’t throw parts at the car yet. Its a misguided belief that parts are needed or will make you faster. The reality is that when you’re starting out on track, the driver is the part that needs a lot of upgrading, not the car. (But do the recommended /service/ items like brake fluid, pads, alignment etc).

after a *bunch* of track days, then maybe consider upgrades. You should have a better idea what the car needs by then.

I think that’s a bit unfair. PP1 might not be the fastest way around the track, but it’s totally drivable and enjoyable:



at the very least, it will re-enforce that smooth is fast.

edit: time dropped from 108.695 to 105.858 after replacing suspension parts, but the videos look basically the same.

I installed the Track Handling kit on my 2017 PP1. I found it to be a Dramatic improvement in every regard. I found the PP1 suspension to be way too bouncy, and would unload in the middle of a turn causing a steering vagueness and requring a quick correction when you least want it. For the money, the M-FR3A-M8A is excellent and easy to install. If oyu have the cash for something better, go for the Ohlins goodness.

I have a ‘15 PP1 with the Roush single adjustment coilovers and I really like them. Mind you, when I bought the car it had air ride (which was meh in performance to me)
The Roush coilovers are just a name as they are rebranded KW’s, but it provided a major improvement in suspension.

Drivable: yes but technically so is a mini van.
Teaches smooth driving: agreed.
Enjoyable: no, but that's subjective.

It'll definitely teach smooth driving as harsh inputs will quickly result in a sloppy line and horrible response time with that wet noodle suspension.

OP could absolutely drive on PP1 suspension for awhile, completely agree. However, driving various cars back-to-back and comparing to a PP1 Mustang, it becomes very apparent how soft the suspension is.

@EddyB21 this disagreement @Dana Pants and I are having is a perfect reason/example as to why you should drive the car on track completely stock for awhile and see what you like & don't like. A lot of it is personal preference.

Agreed 100%. The PP1 package is just fine on track for a 'showroom stock car.

Sure, some swaybars might help, and people like 500+ ft/lb springs on a track car, but a PP1 is still faster than 90% of cars on most tracks. You absolutely don't need some custom coilovers to have fun out there. I drove plenty of track days with only very mild mods to a PP1 setup for the first three years I owned this car.

Pictured: PP1 car with only shocks and one stiffer swaybar at Circuit of the Americas at the apex of T10.

^not to mention that with aftermarket suspension I can do exactly one hot lap before oil overheat. At least stockish I could do several engaging laps until my brakes and tires overheated.

You overheat your oil in 1 lap at Canaan?

Out lap in 3rd gear, one lap shifting, oil temp right into the yellow.

Wouldn't consider that "overheating". Have you checked all your cooling system, something seems off. I can go 10+ minutes hard at Canaan and barely get into the yellow.

Maybe… I could of course just keep driving, but power de-rating kicks in and it’s not that fun.

Coolant was at least 230F and rear axle at least 250F. As those are the temps I saw when I checked randomly in paddock at one point, but I was mostly just watching calculated oil temp.

coolant is there, cap holds pressure, no airflow obstructions, so I have to assume the coolant system mostly works.

My buddy with a stock C5 Z06 was having similar problems with very fast transmission and differential overheat warnings.

Hey Nightmaremoon, what shocks and swaybar did you go with?
