i think the reason i was stripping servo horns and breaking servo savers was because if you add an alloy steering arm instead of the stock plastic one, you need to back off the servo saver almost all the way to allow it some flex. I guess they used plastic for a reason. Basically if I hit hard with the wheels turned into the wall it would break the saver and strip the threads on the horn. Fixed it.
Also since my track changed to click-track, its much more forgiving on the cars. Before we had solid solid wood/steel as barriers...yeah wicked ghetto.
