Help! Where did you find these one-inch 5x4.5 spacers?

Hello! I could really use some one-inch spacers. Are they hub-centric? (Note: I have the 2012 SHO wheels on my 2019 SHO, not the flower wheels). I'm having a helluva time finding:

• One-inch (0.984"/25mm).
• 5x4.5/114.3mm bolt-circle.
• 63.4mm bore-diameter.

The only spacers I found are the 0.984" ST Suspensions' 5x4.5/63.4mm bore, hub-centric spacers from Summit Racing, but they only come only stud-less, meaning I have to find longer, high-grade (10.9-12) wheel-studs to replace the factory studs. Not to mention having to remove the factory studs which are likely frozen solid and will probably require a butane torch and a lot of four-letter words to remove.

The only other option: Buy four brand-new wheel-bearing assemblies. Perhaps there's some performance benefit to this? Or maybe someone makes an upgraded aftermarket wheel assembly for our cars?

Does anyone know if the factory wheel lugs are pressure-fitted?

Note: TCE didn't show any spacers on their site.

These are what I have on my car, very happy with them. With the flower wheels I had to shorten the unthreaded part of the factory studs for clearance, but that wasn't a big deal.

Still searching for a 15mm (0.59") spacer, either hub-centric (center-hole to accommodate a 63.40-sized hub), or a bolt-centric, non-flanged, flat-spacer with an oversized center-void for the hub (making specific hub-diameter irrelevant). Now shopping on the Summit Racing site, I'm now deciding between:

• ST Suspensions DZX #56050137: 0.591 inch (15mm); flanged, hub-centric wheel-spacers. Specs indicate a 63.40mm center-bore diameter (Ford Taurus hub is reportedly 63.40mm).
• ST Suspensions DZX #56055012: 0.591 (15mm); flat, bolt-centric (non-flanged); in conjunction with the ST Suspensions #65250022 center-adapter (plastic hub-adapter).

Bolt-pattern of the ST Suspensions' spacers above are universal and fit the 5x114.3mm (5x4.5) Ford bolt-pattern.
Custom made mine, probably 70k miles on them. No issues or shakes. Checked them last year on cmm at work and still exact measurements when I had them made. IMG 6196IMG 6202

Update: These wheel-spacers have a hub-bore which are 0.01-0.03. too small.

Wow! I checked Amazon again today, and whudduya know? I found a set of 5x4.5/63.4mm-bore wheels in 25mm (0.984 inches). They offer them in up to 38mm- and 50mm-wide (1.5"-2")! Should be here tomorrow.

25mmspacer

Unsure why my previous searches never showed this result (I ended up searching "63.4 bore wheel spacers"). Hopefully, all is well now. Just received a pair of brand-new AC Delco digital torque-wrenches today anyway—they even come with a calibration certificates.

The problem was, the spacers from Summit wouldn't ship for several weeks, so this is a lifesaver. We're planning a quick ski trip to the local mountains since we finally had some precipitation here in L.A.—so that I could finally enjoy the AWD capability of my SHO—a huge reason I bought the car!

Thanks! As I wrote above before seeing your post, I just found a set on Amazon. By the way, these are one-inch spacers with a 63.4mm bore-diameter, correct? (eBay link no longer propagates?)

Glad you found some, and yes 63.4mm.
Not sure what happened to the ebay link, it worked when I first posted it.

Sweet! Wish I had your skills/tools!
Mind sharing the list of parts, still deciding how to handle my brakes project. I would love big brakes in front but don't want to cut/remove emergency brake in rear. Thanks for the consideration.

Update: I am officially an idiot! All hub-measurements were made BEFORE mounting the rotor. Everything below is basically written in error (ignore).

• Several Google searches indicate the 2019 Ford Taurus has a hub-diameter of 63.4mm.
• Measuring with a caliper, the hub-diameter appears to be 63.5mm.
• Problem no. 1: Hub-bore on spacer is 0.1-0.2mm too small to fit over the hub, even after completely cleaning/removing any debris—solution: ground the inside surface of the spacer hub-bore with an abrasive-bit to fit.
• Problem no. 2: There is a 1/4"-tall f1ange at the bottom of the hub—this measures approx. 67.7mm in diameter (see first photo). Second photo shows caliper-measurement of hub at 63.5mm.
• This "f1ange" prevents the spacer from seating all the way, not allowing full-contact with the surface of the factory-hub.

The only solution I can think of is to have a local machine shop bore-out the bottom 1/4" of the aluminum spacers to allow them the clear the 67.7mm-diamter f1ange on the bottom of the factory hubs.

The Taurus SHO Rotora kit includes everything you need except the spacers necessary to clear your wheels (distance varies based on your wheels). I did buy some rubber stops to prevent the brake fluid from sprouting from the open brake-line once the old calipers are removed.

Rotora kit key components:

• Custom bracket for calipers.
• Custom stainless-steel brake-lines w/banjo bolts, etc.

The only other thing you need are 5x4.5 wheel-spacers. Depth will depend on your specific wheels. My wheels are from the 2012 SHOs and require 20-25mm of additional space at minimum from my best estimate.

Typically the only difficulty in adapting other big-brakes is finding or fabricating the caliper-brackets (e.g., someone made some custom brackets which fitted brakes made to fit Porsches able to mount to 2003-2004 Mercury Marauders). TCE Performance and Wilwood make big-brake kits to fit various Fords, but I think the engraved Wilwood logo is so ugly I never considered them.

Thanks for that overview.

Alternate solution: New wheels!

Well, I've gotten all kinds of hub-diameter specifications that don't line-up, so I'm buying new wheels. Unsure if these will clear the Rotoras, but the seller claims they will assist with any necessary spacers or adapters. At least, buying from WheelHero, they have the wheels in-stock and can match-up any necessary spacers to test fitment right there in their Florida shop.

Below is a Photoshop mock-up with the new Petrol P2C alloy-wheels (right photo) I just ordered, and the wheels from a 2012 Taurus SHO (left photo) I had powder-coated black, then mounted onto my 2019 Taurus SHO PP.

1742266004708
1742266110998
1742266870999
1742266550206

I actually quite liked the 2012 SHO black powder-coated wheels I put on my 2019 SHO. I think the after-market wheels are a slight improvement; though, it's difficult to tell until they're actually on the car. Below is a better vantage point to visualize the difference, with the mocked-up wheels in the bottom image.

New tires, too . . .

Since I'm getting new wheels, I figured I'd splurge and get new tires as well, a set of Goodyear Eagle F1 Supercar summer tires. WheelHero will mount, balance, and install new sensors prior to shipping (and will now include the necessary 25mm spacers I need), so all I'll have to do when I get them is bolt them on!

Thanks! Woohoo! So, it looks like WheelHero is going to solve all my spacer problems!

WheelHero: [seller is providing necessary spacers/adapters at no charge!]

WheelHero's website states a 100% fitment guarantee (if ordering via their vehicle-specification database), and if the wheels don't fit, they will assist with any spacers or adapters needed to fit your vehicle free of charge. I just received a reply to my email confirming they will supply the correct spacers/adapters for my wheels.

They work fast—WheelHero mounted new tires, balanced, installed sensors, and palletized everything for shipment all in one day for an order I had submitted just the night before. So in a few days, I should be all set and should the front-calipers installed soon!

Custom Offsets: [NJ-based custom-offset wheel superstore]

FYI: I found another online wheel dealer with an incredibly vast selection—I believe it's literally the largest wheel inventory in the world. Notably, they custom-drill each wheel per order, so custom offsets (plus many other custom options) are available, and most, at no additional cost. If I ever order wheels again, this is where I would go.

Bonoss 7075 T6 forged-aluminum spacers/ISO 12.9 studs:

FYI: In my search for spacers, I found a SHO owner's posts on another SHO forum who successfully installed Bonoss-brand spacers onto his SHO. I emailed Bonoss a detailed report of my fitment issue with the Ford wheel-hubs and they replied immediately with a request to send some photos of the hubs.

Though pricey (double or more than spacers sold on Amazon), Bonoss' spacers employ higher-grade, 7075 T6 aluminum and stud-strength specifications (12.9) superior to that of every other competing brand I found. The only downside is they're not in the US; they're located in mainland China.
