Does someone make a metal dust / grease cap for the front hubs?
I have some 15 mm spacers that the thick plastic factory dust covers interfere with.

It's why our 15mm spacers were made to put the cap in the spacer. You may run into issues with that 15mm spacer on your hubs. The hubs protrude further than the spacer is thick, unless the hubs have been machined down for clearance. Depends on who made the spacer but math is math.

You want to verify the spacer sits perfectly flush on the rotor before putting your wheels on.

Ok, I am running your spacers.
By your response, I assume I pull the grease cap, install the cap on the spacers and then install the spacers.
There was nothing that came with he spacers explaining this.

All of this information was clearly explained on our website:
1. ***Application Note: 2005-2022 Ford Mustangs with a spindle mounted front hub*** The hub/wheel mounting centering ring protrudes approximately 0.100" further than all the other hubs. Our 12 and 15 mm spacers will not work on the front of these cars. All Magnetic-Ride Mustangs, GT350/GT500's are not affected by this.
2. All the 4th generation spacers allow the use of the OEM Dust cap found on millions of Ford vehicles. If you use wheel spacers in the rear, you can utilize a dust cap in the spacer to cover the Axle Nut. This also prevents track pickup from making its way into the area of the hubs. It provides a nice, clean, finished appearance.

Thank you
Could have saved a lot of time if someone had answered the emails I sent.
