Lifted the Wrangler (01) to 4.5" but I'm still on the factory wheels with 31" tires.

As I understand it, I now need to offset the lift with some outward movement of the tires to regain my center of gravity. I believe that I need to move the tires at least two inches to regain the stock figures, correct?

So how can I determine the offset of the stock rims? Is it stamped on the rim somewhere?

As soon as these tires show some good wear I plan to replace them with 33" x10.5's and regear to 4.10's. Don't thinke the 3.07 gears will like the larger rubber.

Factory backspacing is 5.5".

If it were me, instead of decreasing my backspacing from 5.5" to 3.5" to run 10.5" wide tires, I would go with 12.5" wide and around 4" or 4.5" of backspace to regain the COG. The lower backspacing you go, the more strain you will be putting on the heim joints...

Just my $0.02

"heim joints..." as in the ones on the track bars?

Not so much the track bar. The heim (ball) joints at the steering knuckle will be taking extra strain with lower backspacing.

Thanks, I kinda like that concept as it helps to solve both problems at the same time. I was alittle concerned about the extra rubber weight and braking too. Should I be?

You will notice that it won't stop as well with the larger tires due to both the extra weight as well as the larger diameter of the tire. It should be alright at 33" though. A quick fix would be slotted rotors in the front. They help disipate heat better and thus increase stopping power.

You could always do a rear disc conversion down the road to beef up the rear brakes and increase stopping power. There's lots of writeups out there on swapping ZJ stuff in.
