Those are some awesome looking rims in the last posts.

My ex-wife would have been pissed if I put the rims on the counter (lol). Very understanding.

Question: does powder coating effect the method of mounting the tire, so as not to scratch the rim?

A good tire shop won't scratch the face of painted or powder coated wheels. Because powdercoat is a thick coat, I'm told that you should remove the paint where the inside of the wheel mates to the hub b/c it acts like a gasket and affects the wheel torque value. Also if it's thick in the lug bores, that should be ground down as well. Apparently in track applications the heat of the hub can soften the powdercoat and 'weld' the wheel to the hub when it dries. I didn't want to take any chances so I ground off the surface of the inner wheel where it meets the hub.

EDIT/UPDATE
If you plan to powdercoat your Panamera wheels, ALSO grind all powdercoat off of the inner bore of your wheels - the area where the wheel fits over the hub shoulder. This is absolutely critical to do! ..and I'll tell you why:
The tolerances between the bore/hole of the Pana wheel and the front and rear hub shoulder/lip is tight to start with - as it should be. However, if you have a quality powdercoat job, there are a few coats that adds a couple mm to the surface of the wheel. This reduces the size of the wheel bore and makes the fit even more snug - to the point where bolting the wheels on is like pressing a bearing into a race.
..and guess what happens when you do that? Your wheels are pretty much pressed on to the hubs. Get a flat, or decide to change your wheels at the track, you're SOL.
I had to take my car to a capable tire shop where they jacked up the car and whacked the hell out of the inside of wheels with a huge rubber mallet until each wheel broke loose. It was painful to watch.
Lesson learned :rolleyes:

To my eye, the 928 looks better with a more 'solid' wheel. By that I mean a wheel with more material between the rim and hub. I don't know why that is, whether it's what I'm used to seeing or because the car looks a little unbalanced somehow. Not trying to rain on anyone's parade, and I don't think the cars look bad with more modern wheels, but I prefer them on older style wheels. Purely a personal aesthetic.

I put a set of 18" 5-spoke wheels on my 928 and went back to the stock phone dials because the look just didn't work for me. They look amazing on my 951, though.

After 2 years of owning the panamera 10-spokes, my advice to anyone is buy a set of these brushes. The medium brush is awesome at getting between the spokes and the large brush is great for cleaning the barrels. I imagine the 5-spoke guys would just use the large brush. The small brush I use around the lug nuts. I'm not a concourse guy who spends a lot of time cleaning rims - these make the job super fast.

They're different because they hold water unlike a plastic brush. And they're made of wool so they don't scratch the metal.

Anyway, if you have the 10-spoke and you want to get some of your life back, give them a try. No affiliation.

For those of you wishing to add spacers to the rear wheels, I've done it on my S4. Here are the results:

Very happy with these as-new Panamera pull offs, including the center caps.
