tube bumpers are sweet, id like one but i dont have the resources to build one. as for the gears see how you like it stock with the 35's, you can always upgrade later. theres a lot of people that will have different opinions on the subject btu its all a matter of personal preference, why do it if you feel that you dont need to. i was origionally going to spend all the money on gears but put it off and decided it wasnt necesary, and used the money for something else.
