So I ordered Bilstein 5100 series shocks for my '03 Rubicon. The front ones have arrived and the rear will be here next week. My question is whether or not it would be ok to go ahead and install the front shocks while waiting for the rear. Would it be safe to drive it that way? I have the factory shocks on there now. Also, does anyone else have these type of shocks and did you notice much of a difference. Ive heard good things About them. I'm upgrading to bigger tires soon so I'm doing the shocks. I just upgraded the brakes last week. Getting excited.
