FYI,GM has started adding a $50.00 core charge to each new Lower C-6 control arm.So that going add a $100.00 to the cost of a complete sub frame package.I will not rise my pricing until Oct.15th. 2013.Giving those of you wanting a sub frame a little more time to save.And I will lower the cost of complete sub frame's by $500.00 unitl Oct.15th.Also.Making the cost of the first design frame's $5350.00,New design $6350.00.My powder coater shut down and I haven't found another yet.So no powder coating for a while.Thank's Scott.
