OP can you add wheel and wheel/tire weight to the post?

Sorry if I missed it being posted already, but I weighed my OEM 21" wheel/tire combo and it came it at 83lbs.

Thanks for sharing that information! That combo is pretty heavy.

Geez…my heaviest was 78.8.

OE wheels are always porkers. I had a SHO and did TCW wheels and dropped 12lb per side. Yeah 12lb per side.

I dropped ~15.5lbs per corner with wheels and tires then another ~35lbs total with a brake swap.

I was looking at wheels on some various websites and it appears Mustang wheels are pretty much identical based other than offset on what I researched. This opens up a lot more possibilities for wheel choices. Anyone know anything else that's different?

UNBROKEN · Jul 4, 2021

That’s well known…but the offsets just aren’t right for our cars.

TMac · Jul 4, 2021

I just wanted to make sure as some of the wheel options on certain vendor sites do show +35 offsets for certain wheels, which would, I think fit our STs. If you try to find ST wheels, most sites don't even have it as an option.

UNBROKEN · Jul 4, 2021

The offset will be driven by the width for what fits correctly. Personally I don’t like +35 even on a 10.5 wide wheel but some people do and it can help clearance with 22’s if you wanted to run a 305/40.

I need a clear understanding of what thickness wheel spacers and brand, I can use to bring the Street Pack 21" ST Wheels and tires to be even with the fender well edge, for both front and back wheels? Lots of choices out there but what is the correct offset?

The reason they were sitting with such high pressure is because from the manufacturer, they overfill the tires in anticipation of the vehicle sitting for potentially long periods of time without being driven.. it will keep the tires in better condition as flat spots won't form

Is the load rating on Mustang wheels the same as it would be for an ST? Generally, heavier SUV’s and trucks need a wheel with a higher load rating to support the additional weight. I haven’t researched this yet so I don’t actually know what load rating is recommended for the ST.

I know this is an old post but running into issues getting the correct rim size confirmed.

I am trying to get Vossen to make me a set of HF5s and gave them the specs for the stock 21in rims, but they're telling me the size is wrong and won't fit. Specifically the offset.

I'm hesitant to tell them to go ahead with the measurements I gave them as it would be a colossal waste of money if it's the wrong specs.

've even gone as far as getting a subscription to Ford Factory service info and they make absolutely no mention of rim specs.

Can anyone absolutely confirm that the 21in rim specs here are 110% correct?

It seems like the bolt pattern and center bore match the S550 Mustang wheels. Only other variables would be offset, diameter, and width.

It's called UNSPRUNG WEIGHT and eliminating it makes a huge difference in handling, as well as acceleration and braking. Each corner will react much quicker and lighter to bumps in the road as well as spinning up to speed and stopping quicker/easier.

Unsprung and rotational are the same but different. Wheels and tires, brake rotors…things that spin are rotational AND unsprung. Calipers are unsprung. Shocks and struts are 1/2 unsprung…etc.
Losing rotational unsprung weight pays higher dividends than just unsprung weight.
