Did you have to grind the rear lower control arms to fit the Ohlins springs ? Otherwise this seams very close to what I have as a suspension setup still need to install Whiteline endlinks and send Ohlins for rebuild before getting proper corner balance of the chassis though.

Yes we had to do that!!
I also followed your example with the Steeda Mustang IRS Subframe Alignment Kit!

You might need to fallow my other one with the Steeda Diff Inserts Bushings in order to protect the OEM diff bushings. I'm going with Red there and that alone make a huge difference to lap times. I'm sure this is supposed to work together with the Subframe Alignment kit.

Ok sound like a good idea!
Now it’s time for the setup of wheel alignment, cornerweight etc.
Would you be able to provide me with a good starting point for a track car? Camber front and rear, Toe front and rear, Ride-height front and rear(and were you measure it)!

Great info thanks!
Im going to use Wengard for the ECU and Transmission tune after recommendation from ESS. Hopefully you all have good experience of them as well.
So are the clutches a good upgrade? Valvepack? Ive bought the Mishimote transmission cooler hopefully that will work.. After reading all the posts here im thinking of adding another cooler in series, any thoughts around that?

A huge IC I have and after your suggestion i going to try to box the front cooler in and i have a GT500 hood for trying to let the hot airflow out..

Final question around your 10R80 tune, are you sure you can trust the "manual" shifts? (I cant right now with the stock auto)
I dont want it to start auto shifting in the middle of a corner or shifting when I want to stay on a gear since I know a corner is coming up..?
Im not familiar with the new auto gearboxes but can you make sure it lock up under power or is it always slipping like a older Auto?

I also read your posts around the bypass valve and just have a question around cold climate.. Any experience there? lets say down towards close to +1celcius? what happens before it gets up to working temprature?

Regarding the engine Oil cooler i read some of your post somewhere that the 2018+ S550 have a quite good oil-water cooler?! true?
As mentioned earlier i went with the mishimoto water cooler after reading another of your posts somewhere.... ;-)


Finally whats your suggestion on getting the weight down?
My list is:
LILO battery.
bucket seats
rear seat delete

What else in weight reduction if I still want it to be usable on the streets which was the issue with my old car it became to crazy....

thanks for your input!

Rsa "built" And stages is an ...interesting MARKETING CONCEPT.
Stage 1 "build is : better clutches
U can buy them for 600$ (McLeod requests clutches)
U don't need a "better" torque converter cause the stall thing is just for drag racing.
And a good tuner can lockout the clutch at 20mph anyway.

There is one torque converter that is better and us the SUNCOAST PERFORMANCE ONE but cost more than TRANSMISSION.

U can have better valve body circuits but the efficacy has to been proven still.

Better trans pump? Maybe.

My thermal bypass together with a bigger cooler is what is working for me.

Note on the supercharger. You will be pulling timing. Pretty soon.
Also keep in mind. You want to have a big engine oil Cooler.a big trans cooler. And u need a huge intercooler too. Not sure where you going to get the space. And does that ruin the whole cooling? Probably.
For a time trial car the supercharger or even better twin turbo (lighter and the weight is waaay lower so better handling too)
Is a great option. If you plan to do more than 5 laps you may want to reconsider that and use a full bolt on engine keeping it NA. Oztuning is the way to go
many real racers use KEN and he is great!
Get a better manifold. And you are more than 500whp. Than the secret is weight reduction. You drop 200kg. U gonna love the car!

Alex @flyhalf I have not driven my Mustang much but I feel the gearbox is quite slow and hard to control and not stayin in gears despite me having it in manual race setting... Whats your opinion? How do you control it?

I didn't do a proper corner weight so my ride height is where the Ohlins are initially setup around 370 mm from center of rim to fender. Regarding Alignment my current one is F: -3.3 degrees camber, -3.3 mm (-0.33) total toe R: -1.5 degrees Camber, +3.0 mm (0.3) total toe in. Here is a link to a Dark Horse R setup sheet which might help you: https://performance.ford.com/conten...-challenge/pdfs/DHR_Customer_Set_Up_Guide.pdf

A couple of months back I bought a S550 Mustang GT 2020 (10R80).

Its my first Mustang and actually my first American car but Im in the start process of trying to build it too a quite fast but versatile track car..


As a background Im a real rookie to Mustangs but been racing(Circuit and TimeAttack) and building a Porsche before on a quite high level.
The thing is that in the US the Mustangs are super common but over here in Sweden the are only known for running of the road all the time due to really bad handling... ;-) That was quite impelling to me since ive been reading up on them a bit and realize they we have some hidden potential here to scare and potentially surprise some Porsches at the track.. I set my goal pretty high and the idea is to be able match a Porsche 991Gt3RS at the track... I think going after a 992 would be to much of a ask but a 991 should potentially be doable...

Any way im right now in the process trying to figure out the recipe for doing it but the issue with mustangs is not that is hard to find parts, its the other way around with to many options!! ;-) ;-)

Ive been "stalking" threads from FlyHalf and others on the forum but not written anything since im a rookie with not much to add to the discussion but eager to learn a bit more and think I picked up a little from your great and fast builds on the forum, especially FlyHalf..

The recipe in my build right now look like below and I would be super grateful for some suggestions, objections, tips and tricks!




Mustang GT 2020 PP2 EU model

Engine/transmission:

Mishimoto trans-cooler

Mishimoto main cooler

Mishimoto 71C termostat

K&N catch-can
ESS G3X supercharger with G4-IC

WG controlled boost to get a little more midrange and less top-end.

Arcane dual pump fuel system

1000CC FIM injectors

E85 fuel

Boundary Racing Pumps Billet Oil Pump Gears; MartenWear
Boundary Racing Pumps Billet Crankshaft Timing Sprocket
X-Pipe
Cat-delete


Wengard tune for engine and gearbox
 Idea is to run aprox 700-750hp on track and try to keep the cooling in order which Ive seen is really hard on the 10R80(Next step is potentially a RSA built transmission).



Body:
GT500 vented hood

GT-style rear wing
Ducktail rear spoiler
Front splitter

boxed coolers in the front.



Wheels:
Velgen 20x10 front
Velgen 20x11 rear

pilot sport cup 2 305/35/20 front

pilot sport cup 2 325/35/20 rear


Chassie:
Whiteline front swaybar
Whiteline rear swaybar
Whiteline vertical links

Adjustable Toe-link s rear

BMR Rear Camber Adjustment Lockout Kit
Maximum Motorsports Caster/Camber Plates
Coilovers not bought yet but the idea is Ohlins Road & Track, what do you think of those? Also some suggestions on spring rates would very much be appreciated!?

Overall around chassie im very confused because of IRS braces etc and other stuff that I never seen on a Porsche?!?

I'm also not sure what else I should do to get the most out of the chassie with out re-doing everything Ford built, im not sure what give the most and I dont want to through money in the ocean that does not give anything useful.

Its also a lot of stuff sold for the IRS back-end but not much for the front?!? Any ideas suggestions?!



What do you think overall, what have i forgotten and what am im doing wrong?

Just checking in to see whether you ever got this beast on the track and whether you were able to keep it cool with the ESS supercharger and how well the WG boost controller worked.
