Add to that, even as little as 4.5" of BS (stock BS is 5.25") on a 15x8" rim will give you a even wider stance. Approx 2" wider at each tire, so 4" wider in total. Use a 4" (or 3.75") and gain about 5-5.5" of stance, not including the wide of the wide pattern over the 8" of rim.
Keep the sway bars on the front and back, and there will be little to no change in the handling. If you are worried about the rear getting a little sloppy, summitracing.com sells some bolt on load leveler helper springs that will actually tighten up the rear as well. These units are easily bolted on and off.
couldn't have said it better......
33x12.5 tires are nice and wide.....really stable!!
4.5" of lift isn't really that much compared to today's lifted trucks. You are proposing a 4.5" w/ 33s. This is a great combo: the typical small lift with big tires setup (low COG). Some guys run 5.5 to 8" lifts on XJs, now for these your step dad would have reason to be concerned.....
I run what you are proposing, it is great, and very stable. It isn't a sports car obviously, but thats not the point. I used to run 31s, now I run 33s which are even more stable. I only use my front swaybar, sometimes not even it, and I'm still fine.
You could try to argue that sitting a little higher may actually increase safety a little, around all of the monster SUVs on the road today. Sedans/ small, low sitting vehicles get crushed in accidents by the heavy weight trucks/SUVs of today.
By the way, there are countless engineers who offroad with their lifted 4x4 vehicles. They know what they are doing. I know an mechanical engineer who works for the University of California and owns an amazing '71 Bronco modified to run 35s.......
