Sorry for starting another thread guys! I just got a lot of questions and no answers were found after hours of searching!

Well anyways, anyone with rpf1 15x7 using hubcentric rings? I know the center bore for the wheel is 73mm, and the hub bore on the GD3 is about 56.1mm, don't quote me on that. With the difference in sizes so huge, what hubcentric rings did you guys use if you guys used any, thanks in advance!

 

I'm using plastic hubcentric rings for my RPF1.
Any tire shop will have them, they cost about $20 in Canada so probably cheaper in the states.

You just need any generic hubcentric rings with inner size 56.1 and outer 73mm.

Many people don't use hubcentric rings without any issues, but it's such a cheap part so better safe than sorry.

There are also metal rings but apparently they have a tendency to seize onto the hub, plus they are more expensive. Plastic ones may deteriorate faster though, so it's really your choice which one to get. I would just get the plastic ones and call it a day.

 

I got 16x7 RPF1s from TireRack... they came with plastic hubcentric rings.

They're so snug, that when there's a coating of rust (I didn't buy the center caps)... they're a bitch to pry off when it comes time to rotate my tires (too much force, and you mess up the rings!). GAHHHH. I gave up and pretty much hoped that ALL four stay on the car... cause it's a PITA when two are on the car... and the other two came off with the wheel (needs a little knocking to get it loose there too!).

The reason why it could work without the rings... is because, when you put the bolts on, so long as you constantly shake the wheel as you tighten the nuts (by hand), the nuts will eventually center the wheel itself. edit: http://www.tirerack.com/FAQ/results....gory=Wheels#70
