I put a set like these on my daughters bike when she first started riding.

We didn't drop the front at all.
She was much more comfortable at stops, but quickly was scraping hard parts in sharp corners.
When she upgraded to a Harley Sportster she wouldn't let me lower it even though she was on tip toes when she stopped.
