4x100 BBS RZ center caps questions

[E21intheRockies]

Hey guys, my first post, hoping to get some help.

Looking for info on the right center caps to get for my RZ's.

My wheels are 15x7" 4x100 et 20

Very confused by the variety, so what interchanges?

I've seen pics of the centercaps for 14", 15" 16", euroweaves, style 5 and they all seem similar, but I've read that there are differences in the way the back attaches to the wheels.

Have spent hours poking around and can't figure it out . Some one break it down for me please

And is a 15x7" 4x100 et 20 wheel the same as an euroweave?

TIA-

the actual metal center cap is different, the black backing disc and the cap nut are interchangeable

So what you probably have are BBS RZ378's. The BBS RZ320 is a "Euroweave" is 15x7 et24. Yours will have more of a dished lip than the Euroweave. The 14"(BBS RZ305) and the 15" one piece cast RZ's in e30 fitment all attach the same way (with a hex tool, or your hands in a 1/4 turn clockwise to attach). The waffles that attach to the hex and locking rings are different between the 14" and 15". If you're looking for caps for the 15", you cannot use a waffle for a 14" cap. The 15" Euroweave cap is the same as the "ix" weave cap, and will work for your RZ's.

If you'd like, PM me your email and I can send you their hardware guide, listing all the part numbers and combinations.

I have a set of BBS RZ wheel caps, but I cannot make it fit on my euroweaves. The lock system is different, but looks like it'll work..but it doesnt. Any advice?
