I like driving fast off road even better than crawling. Nothing serious, just weekend fun. I built a Ford Focus and a 2wd Ranger for fast dirt road work and they were a hoot to play rally racer with.
I would like to do some fast work with the JKUS. The suspension feels pretty good, but it feels like there is a lot amount of unsprung weight. The Goodyear SR-As are no good as they are passenger tires shouldn't hold up against punctures. I blew one out in my first quarter mile of gravelled logging road at only modest speed.
However they only weigh 36 pounds and a suitable tire of the same size is going to weigh quite a bit more.
I found that even with my light weight standard cab short box 2wd Ranger that standard shocks would overheat and quit working properly in short order. I would think this would be an even bigger issue on the heavy Jeep.
Anyone already been down this road?
