2013 Scion FR-S: Installing Mag Locks

August 22, 2012

Excuse me if I call them mag locks. I know full well that our 2013 Scion FR-S doesn't have magnesium wheels -- they're forged from 6061 aluminum. What can I say? It's a habit.

On the other hand, the 6061 aluminum alloy does contain between 0.8% and 1.2% magnesium, so I'm not 100 percent out to lunch.

Anyway, our new Ray's/Volk TE37 SL wheels were mounted with skinny 17mm lug nuts that don't fit the supplied lug wrench. It's made for 19mm lug nuts.

No big deal. I have tools.

Installing the new wheel lock requires a special socket, of course, keyed to the match the shape of the external fluting. The only problem is the smallest step of the key fits with a 19mm socket. You can see where this is going.

No problem, for the moment, because I've got one of those, too. The wheel lock package suggests a tightening torque of 75-85 lb-ft. I decide to go with the high end of that range.

All done. All I need now is a lug wrench for the trunk that can handle 17mm and 19mm lugs because now we've got both to deal with from here on out.

I think I know just the thing, and it isn't shaped like an X. Stay tuned.
