I'll have a pic posted tonight. model is rs300's. I think they came off of a toyota.

 

on my old sets of bbs rims i just used shorty acorn lug nuts and it came off a nissan oem/option..i am not sure if it was correct but i did not experience any vibration..etc

 

Probably conical aftermarket lugs.

Since you have the wheels, just look at and feel the area around the holes, the area where the lug nuts are in contact with the wheels. If the shape is tapered, it needs aftermarket lugs with a conical seating area; if it's ball-shaped, it needs OEM lugs with a spherical ("radius") seating area.

 

found these pics online. mine looks eaxactly like it.

 

It's hard to tell from a photo. Sometimes it's hard to tell by looking. I find it's easiest to just feel the shape of that area with your fingertip. You can do the same with a stock Honda/Acura wheel (like your spare) for comparison purposes.

 

yep..ken is right..just get a feel for it..that's what i did on my old rs rims.. and they worked fine
