I want to add my 2 cents now that I have actually been out on my 35's. Im on 35" rockzillas and I did a 12% across the board gear reduction. I went out last night and did some legit rock crawling on some pretty nasty trails. The 12% in low gear was plenty even on steep inclines going over boulders where the front end was pointed up so high the headlights weren't shining on anything. I am NOT the majority when it comes to gear reduction preference but I honestly dont see how the car is even usable when you do the 33 or 50% reduction. I fell in the back of a line of canned hams that were all struggling to go over stuff at one point that I was just crawling over effortlessly.
