Drag Racing Tech - Drag suspension gurus in

I have a question regarding rear springs and relocation brackets for drag racing. I hear that the stock springs are the best for dragging on Adj shocks, but what about relocation brackets? I currently have a 1" drop on the car with reloc. brackets and I need to know if I should keep or remove the brackets when I go with stock springs in the rear. Will I see more traction by doing the swap? What's the best combo for traction in the rear?

I currently 60' 1.61 on a YTP4200 on a 17" ET Street.

Thanks.
