I would follow UnlimitedLJ04 advice. Also, just my 2 cents worth (adjusted for inflation it's a bit over 1 cent) but at 6" your center of gravity is going to be high. I have a 97 and a total of 4 1/4" of lift. With some modifications including what UnlimitedLJ04 mentioned I could fit 35's if I wanted. It would take some work on my part. On yours, you should be able to run those 35's with a bit of modification to what you already have so that they don't rub. Quite a bit of work is required if you're going to add another 2". Remember that the TJ's are not as wide as the JK's so there is always risk of raising that center of gravity.
