Lug Nut Upgrade

I've yet to meet anyone who likes the sheet metal wrapped OEM lug nuts. They are universally hated. It's just a matter of time until your tire technician spins the sheet metal with an impact gun. My Blackwing came with M12 X 1.5 stainless lug nuts (and lug nut locks). I decided to preemptively replace them and since my wheels are satin graphite I switched to black.

In the past I've used McGard but the RPO SPY black lug nuts (GM 85553525) are actually nice. Instead of ordering as a $275 option, I paid $100 less and installed them after I got the car.

Magnetic Oil Drain Plug

In early 2007, GM switched from using oil drain plugs with a magnetic tip to drain plugs without. The obsolete part number for the OEM version is 88891787. These pop up on ebay from time to time. The threads are M12 X 1.75. These are also available from the aftermarket, e.g. the Dorman 090-936CD.

A magnetic oil drain plug will pick up ferrous metal particles that are smaller than your filter can trap as well as those that it can trap. Since I don't always cut my filters open they give me a quick check for junk that might be in the oil.


Aluminum US Flag

I'm not really big on putting decals or bumper stickers on my vehicles but I like displaying the US flag. I got this aluminum flag from ebay.
