What is the savings with buying the mark hubs and having them redrilled? Looked at new hub-88's and with shipping was going to be around 100 a piece, then having to purchase studs, pay for redrilling and shipping back, wouldn't the cost be close to the same as buying the cobra hubs off summit for 156 a piece with free shipping? Just trying to make this decision myself. I have new front hubs and cobra bakes, still trying to decide how I am going to spend my money on doing the back half.
