I ran mine with the rear lowered 3/4 of an inch and stock height front for 2 years.
It handled better in sand and was a little more stable at speed in dirt, it still cornered fine, it didn't push the front in corners. I never noticed any difference on pavement.
I raised it back up to gain clearance under my skid plate as I was getting hung up more than my buds bikes. It turns a touch quicker now that's the only thing I notice until I'm in sand then the fronts wants to dig in and stop while cornering easier than it did before.
This bike handles fine either way, if I rode in sand a lot I'd keep the rear lowered but I don't spend too much time in sand.
The down side to lowering the rear is slower turn in and possible pushing of the front tire in dirt corners.
Try it with the rear lowered and see if it corners to your liking, if it doesn't lower the front until it does.
