I have Volk GT-7's and I just purchased the Volk centercaps, but I just can't seem to figure out how to put them on. I have tried twisting them on from the outside and even tried taking them off to realize that I put them on completely wrong compared the pictures that I have seen. Please let me know what I'm doing wrong. Thanks.

 

where did you get the caps? I want 4 of them too for GT-N's
