I cant find my set of sockets. What size socket do I need to remove the wheel on the 21" rims? 19mm or 21mm?

 

19mm.

 

Turned out to be 21mm

 

Nope. Lug bolt is 19mm.
If your LC is on lug nuts, it might be 21mm as other Lexus lug nuts.

 

The factory lug bolt is 17mm......

 

You are correct. But his choices were 19 or 21mm. :P

 

I thought I made it clear I was looking for the correct "socket" size to remove the lug nuts. It's 21mm on my car.

 

Nowhere in your post saying that it's a lug nut.
Anyways, you got your answer.

 

Thanks Nick!

 

I should've done a better job. But when you asked if it's 19mm or 21mm, I took those two sizes and the 19mm spun the lug bolts I got and the 21mm did not. So that' why I said 19mm. But in fact, it's 17mm for lug bolts and 21mm for lug nuts.

 

So whatcha doing with your wheel off down there?

 

Spacers, when I get some time.

 

Im confused now what just happened
