Got my Mazda all fixed up, so I spent some time and money on the Bronco. I went from 1.9 tires to 2.2's, so now it has 4.8" tall tires on it. The math works out to roughly a 44" scale tire, since the body is about 1/9th scale. I also stuck the longest shocks I could find on it, they're just under 6" long. I've got zip-ties as down-travel limiters on the front and rear, and they don't interfere with articulation much and the front one is only there so it doesn't throw the front driveshaft so easy - my driveline angles are absolutely horrid - about 50 degrees on the front transmission u-joint at full droop without the limiter. I'd re-locate the tranny, but the lower suspension links attach to it. I'm working on a fix - I'll probably have to make a drop bracket setup that has integrated suspension mounts, but I need to keep it strong, I run this thing pretty hard. I'm very pleased with how it drives now. I also killed my rock crawling motor - so I went back to stock. The huge jump in power was probably for the best with tires this size. It powers through about any mudhole I can point it at.
