Thanks guys, there’s something about it I don’t understand. Now I’m not a young guy anymore and don’t want to get hurt in a car but when I open it up and it hits second gear hard the tires will break loose and it goes hard left. I lift because it scares me.
Is there some way to adjust the rear suspension to stop this. I’m not going to race this car but I like to open one up now and then.
