I would not recommend removal of you rear sway bar,it ties the lower control arms together helping to keep your diff centred. Also if you want to gain traction you want to remove weight from the front not the rear ie.weight transfer.As for removel of bumpers think about that, we all think we will never get into a accident! What do you think would happen if you got rear ended or head on i know i would like to have my bumpers it aint worth the extra 10th
