i would do the support so you dont run into tunnel cracking like people haveing with the bdx bumper kit. thats why i went with van amburg
I didn't even know this was an option, too bad because it looks great. I did the BDX kit on my 04 last year and haven't seen any issues with cracking and I get stuck a lot This year I dumped the garbage BDX gusset things and put on 09 edge grips and gussets.
