1. What year did jeep start coming with the sunrider soft top?
My 08 and 09 had it. Not sure about 07.
2. Is the lug pattern for jeep the same through the years or is JK different from TJ and so on?
no... TJ 5x4.5. 2007 on JK is 5x5.
3. At what lift height do you have to change your driveshaft for length?
Depends on 2 or 4 door, auto or stick, year model etc.
TJ's almost immediately.
JK's 2.5" no problem for me on a auto 4 door with the rear. I always change the front immediately with a lift to protect the transfer case (were some exploding transfer cases on hwy with stock shafts). At 3.5" I should replace the rear now.
4. Whats the biggest tire that can be run on the new rubicon wheels?
I had 40's on mine on my previous jeep waiting on my beadlocks to arrive.
