So i have finally got my toy from my wifes clutches, 00' xj 4.0 np231 and d35, i had decided to peice together my lift, 3.5" re springs, rc shocks,rc bar pin elims,sye with an rc driveline, and i plan on using 31s for now, my first question has to do with the factory abs system, ditch it? Or use it? And the rear swaybay gets tossed as well? Thanks
