Philostang,
Ahh makes sense now, thanks. I like the pure function looks of those matte black FN01R-C's but those PF01's are really sweet and -4lbs/wheel is significant.

Thevesh,
I'm seriously considering the RPF1 18x10. What are the fillers rings that you had made? Were they necessary in order to install the wheel?
Thanks!

 

As a hub bore on the wheel is slightly bigger, couple of millimeters, I have made approx 1mm thick rings which I put inside the wheel for better centering on the wheel hub. To be honest I don't really think those are necessary. Just tighten the screws precisely to center the wheel and you are set even without the ring.

 

Awesome, thanks for the clarification.

 

See this thread

Mine came with the rings installed by the supplier.

 

Sleeper_08,
Thanks for the link to that thread, I was a little fuzzy on some of the math but got the gist of it.
So your PF01's came with rings for Mustang diameter bore?
Thanks again!

 

Yes they did. I've had it up to about 100 mph with no vibrations.

I should find out tomorrow how they perform.

 

Cool, let us know how they performed.

 

They were great. I'll hopefull post video and data later in the week.

 

Excellent! Can't wait to see it.

 

I've had the Enkei RS+M wheels for over three years without centering rings. As Thevesh says, a little care when installing the lug nuts (be sure the first two are centered in the bore) and there are no issues.
