Do you also sweat those cool little details?

I think it's worth the $15.

If I had a set of TE37s, I'd spring for the valve caps, too–and probably a couple of bags of replacements as well.

Now you need centercaps :)

In 1985 I bought little steel caps for my 1985 Nissan 200SX.  A coworker stole them from one side planning on the other side in the future.  Another coworker saw a guy bend down by my car and told me but wasn't interested in getting involved.  

I asked the guy and he started yelling at me so I've learned not to care about those caps.  The black plastic ones work fine.

Would you believe that I have them–but am too afraid of losing one on the road. 

OG Volk TE37 center caps:

Never...

I would certainly never order a set of green Bentley valve stem caps to go on my green Bentley. 

Or a Bentley tool bag to go in the trunk. (I couldn't find a green one. Trust me, I looked.)

Never. 

Small update: I now see those Rays valve caps on sale for $12.76.

I've tried to but it seems to go down the dreaded OCD loop: You get all those little details just so and then see one more detail that would be that little bit better with one minor tweak, and that tweak begets another and another.

In reply to Tom1200 :

I hear ya. Somewhere there has to be a hard stop.

Rays valve caps? Yes.

Refinishing the wheels to like-new? No.
