the 247 is much better than the 249. in 4low its the same as any other jeep tcase. NO worries. keep the AWD on the street, 50/50 split in the dirt
BB from Modern ran me 475, that was with rubicon express monotube shocks. they had it in stock. i run a 245x75r16 mickey thompson ATZ (measure 30.7 or something like that) as far as streetability, i can't tell any difference at all. its stock. i haven't wheeled it yet, but i plan on wheelin the WJ at the 101 this year with TREVORS WJ as well (yes buddy i AM pressuring u)
moderate trails it'll be juicy i bet.
as far as 4" lifts go, checkout
www.zoneoffroad.ca they have a 4" WJ kit thats ridiculously reasonable (900 to your door) or something like that. you can clear a 32" tire with that lift. that tire will probably be laggin on the stock drivetrain (especially the 4.0L but V8 should be ok)
i've researched the thing myself and can't find much to be honest. I really wanna up grade from my 2" to that 4" and run a set of rubicon takeoffs............ Ironrock offroad makes similar products i guess, but its all USD......... heres a link to that particular kit.
http://www.zoneoffroad.ca/default.cfm?fa=products&ProdCategoryID=39as far as the WJ, it resides in Edmonton and i almost bought the damn thing but somebody beat me to it! he's already swapped a new motor into it and all that too the lift on it is claytons, and it retails 2999.00 USD
ps, W squared, if ur buddy wants to come by and take a look at a WJ on 2" with bigger tires, he's more than welcome to take it for a spin
