My stock sport wheels are powdercoated black, but they couldnt do the center caps because they are plastic.

I dont really like the look of the silver ones with the black wheels.

Do they sell black centercaps for them anywhere, or do I have to paint them? Also, what about black lugs & locks?

 

you'll have to paint the centercaps yourself.

and for lugs check these out. they are great

Thanks, but yikes, $250 is a little out of my budget.

 

those are the BEST locking lugs you can get. you won't be able to get any kind of quality locking lug for much less.

I've got some very high quality brand new lugs (WePro FORGED 7075) I'd sell you if you want them, but they aren't locking

 

If you have stock wheels, you'll need to use stock type lug nuts, not tuner lugs.
