How much will the stock rockers take? I really want to get this project going for this year but the budget is taking a big hit. What are the limits of the stock rockers? I planned to buy a set of T&D but I just can't swing it. What upgrades are worth it? Using Thitek heads (reason for the budget hit) I know the stands are better so are the tie bars worth it? After market shafts worth it? What has been everyone's experiences?
