Given our endless potholes and curbs that jump out at WAGs, I decided to forgo my desired custom forged wheels in favor of some flow formed Ferradas. With limited options in the 5x108 market, some friends assisted in some semi-custom pieces to get what I was looking to achieve:

Ferrada FR8 | CONTINENTAL EXTREMECONTACT DWS 06 PLUS Ultra High Performance All-Season
20x9 ET35 | 245/45R20 | 52.0lbs
20x10 ET45 | 275/40R20 | 55.8lbs

*Ford OEM GTPE wheel + 245/45 PZero combo weighed 60.4lbs each. So I’ve shaved ~26lbs off the rotating mass, while adding a bit more contact patch.

Maintains OE height and balanced stretch. Outer sidewalls are pretty close to flush with fenders, which was the target. Initially we planned to mill down the fronts ~3mm and rears ~2mm to target ET38|ET47, but these off the shelf offsets look like they may work out good as-is.

I really wanted the maximum concave I could do, but given OE offsets it’s tough to accomplish unless we go pretty wide. Curious how a 9.5/255 & 10.5/285 setup would play out (maybe next round), but really not too much room out back to work with… The rear plastic fender liner is pretty close with 10”|275, but this can be pulled back some without much work

*Weather here has been crap the last week, so parking garage photos will have to suffice... Also note the susp is likely not settled on the ferrada side comparo shots

I went to a shop looking for a similar setup and they said not to do the staggered setup on all wheel drive. Thought?

Did you find load rating for these? They look great but flow formed wheels have gained strength on the barrel and not the face or hub of the wheel and given the weight of our cars I worry about that design.

Tesla Model Y Performance and ID4 AWD/GTX have staggereds.
Maybe be we are not connected to a transmission. Cool I'm thinking of the Vossen HF2 in a 22x9.5 f and 22x10.5 rear. What are your thoughts on that set up.
Thanks

But, the MME chassis engineers were instructed to maintain a neutral chassis balance/handling traits to go with the 50/50 weight distribution. Because that’s part of the Mustang handling balance they wanted to emulate. Staggered setups by design increase understeer, which, for handling fans is generally a no no. Most OEM staggered set ups are done to specifically tune out some inherent oversteer, and thus, make the car “safer” on the road for drivers lacking talent/track experience, i.e. most drivers.

I’m not saying staggered setups are bad, just that they are generally specified as an integral part of the chassis tune, not just for looks etc.

And who wants to tear through expensive tires because you cannot rotate them. Staggered look good, but I'm an autocross guy myself. Square is best.

Amen brother! My car has a factory 245/40 275/35 stagger and even though the handling is a high point, I was able to tune out most of the corner entry and mid corner understeer by going to 275 square. The understeer was slight owing to the 50/50 balance but now it’s almost all gone. And as you said, tires cost $$$. So I only buy Conti EC Sport or Michelin PS4 summer tires since they have 30K mileage warranties, when I wear them out at 20-22K I get the next set for 30-33% off at Discount Tire. With the stagger the warranty was only 15k miles.

Nice rims choice. I hope that you like those DWS tires. I bought a pair for a different car and handling went completely out the window. The rounded & soft sidewalls made it handle as well as a minivan. Have you had a chance to take the car out for a spirited drive yet?

Nice setup, I went with 22’s myself for mine.. I got a question though, where can I get a set of GTPE rims… I got another Mach-e coming for my wife and it comes with 19’s that I want to replace without breaking the bank

I think GTPE rims go straight past breaking and into robbing the bank. Isn't the Ford msrp around $1K/wheel? Even the usual discount Ford parts sites aren’t going to get you below $3200-3600 a set. Maybe eBay?

I'll sell you mine with tires under 500 miles. Has the 245/45 p.zero
Make me an honest offer. Shipping might be tough. I'm in so cal
