5100 with OME dakar leaf pack

Hey guys, sold my 07 trd with a 6 in adjustable coilover back in may and just took delievery of my 14' dcsb sport. I purchased a set of OME dakar leaf packs and nitrosport shocks for lift in the rear. for the front I ordered a set of 5100's and I plan on setting them to 2.5. I have a fiberglass cap ordered and down the road I plan on adding slide out drawers in the bed. I am also going to be putting a steel plate bumper on it. Should I get the 885 coils and set the 5100s at .85 or will the stock coils at 2.5 be fine?

OME Lists the leaf pack at 2.75 and from what I've researched the stock coil set at 2.5 I will give me close to the same. Plan on installing a set of 285x70r17

Thanks for the help
