Question about new wheel setup

[djhtech]

Well, I've decided to purchased all new 4's -- here are my contents in route:

- Toyo Proxes 4 275/35/18 (front)
- Toyo R888 305/35/18 (rear)
- XXR 521 Black/Polished Lip 18x10 (all around)

During my order process, I was prompted for this "install kit":
http://www.nlmotoring.com/Circuit-Performance-Wheel-Installation-Kit-p/wheelinstallkit.htm

I ordered it as well with these specs:
1/2" Black Bolts
73.1 -> 70.6 Aluminum Hub Centric Rings

Now, the question is.. Do these rings serve the same purpose as the LFP hubcentric spacers as they look nothing like each other? Are these "rings" spacers or just special adapting rings? Do I need the LFP 3/8" spacers (18x10 setup) AND these rings?

..or should I toss these things? .. I just received them today, they look like big c**k rings.

Thanks!

I suspect that those are adapter rings as the XXR rims are usually universal--fit more than one type of car.

I dont have any experience with them so you may need a spacer to get fender flush/make those tires fit without rubbing.

That's what I've been told (universal fit). I will check for pricing on the LFP. Anyone else?

The hub centric rings allow the allow the wheel to fit properly on your hub not loose. They help by eliminating vibration/wobble and reducing stress on lugs.

These centric rings will fit on the lfp spacer.

Okay, great. Thank you for the answer I've been looking for!
