I personally don't like the guide bolts. In my opinion they make getting the wheels on/off more difficult, especially in front as the hub tries to spin while you are trying to line it up. I've had my wheels on/off my car probably 20+ times.

For us plebs without an impact drill - I recommend loosening the wheel bolts while the car is still on the ground, and then jacking it up from there.
Also, the way I was taught - don't fully torque wheel bolts when the car is still up in the air. Get them "snug" (without exerting much effort), lower the car to the ground and then torque them at that point. Don't forget to re-torque the bolts after 50-100 miles, too.

And yes, no final torque wrenching until the car is on the ground--see my step 10.

Ah, sorry, I missed the torque note between all of the pics!

Here's another source. These are smooth rather than have the knurled end which would appear to be better for the paint on the wheels. https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1

You can easily make wheel guide studs from 3 1/2” (90mm x 14mm, 1.5 fine thread) hardware store carriage bolts by cutting off the heads with a hacksaw and tapering or rounding off the cut ends with a bench grinder or file.
Use two of them when mounting the wheel and the front hub is less likely to rotate.
