like the title stats what is the point of these is it just for looks so your lug nuts stick out further or what i dont understand. if anything you'd think it would be weaker since its easier to break a long skinny thing compared to a short stubby thing.

Pros:
-easier to install the wheel
-allows safer use of wheel spaces by using all the threads of the wheel nut
-more warning of a loose wheel nut before it falls off

Cons:
-takes more turns to install and remove wheel nut

Assuming you are not buying junk, strength will be the same or better than and OEM. Extra length makes no difference in strength - you aren't using the threads past the lug nut.

It is preferred to use the style of extended stud with tapered ends, easier to install wheel and wheel nuts.
Be sure to check the knurl diameter. Some extended stud kits may require you to drill the hub holes out as the knurl diameter is larger than stock.

 

Using spacers to adjust wheel offset will generally require the use of extended studs to make up for the spacer thickness. These studs should be very strong, as moving the rim off the hub flange will cause the wheel stud to bear the load of the vehicle, making snapping a stud a very real possibility.

You should always use rims that are hub centric with the correct offset from the manufacturer, this puts the weight on the wheel hub flange, where it should be.

Using lug centric wheels leaves too much risk in the area of snapping a stud, or losing a wheel.
