I have see Vas' video. I have already put 125k in all the diffs. I know I need higher in the center. I have also put 50 wt in the shocks. I don't know much about tuning a car. I usually just grip and rip. I have read, studied, and looked up on most of it. Maybe I just don't get it. These high powered, 1/8, 4wd cars are new to me. I would like to be able to run it with out breaking it due to a setup error. I know cars break, especially cheaper ones, but most of my issues are user error. I saw Vas' 4 and 6s runs and my runs are ugly compared to that. Again tires will change a lot, this I know.
These things are always broken.
