ARB bumper and winch suspension

I've recently got a smoking deal on an ARB summit bumper ($500) and just had to buy it. However, the additional 170ibs as well as the addition of a winch, slider, and skids in the future make me concerned about suspension. I have not mounted the bumper as I don't want to have the stock coils bearing all that weight and I wanna do the lift and bumper at the same time.
I want 700ib coils to minimize the amount of pre load of the coils. I've looked seriously into wheelers off road and their Bilstein 6112 with 700ib long springs. However, for the price, I like the eibach pro truck lift (as seen on tacomabst) since it would let me save some money for tires. However, the I'm not sure how the kit would deal with the weight. Any experience with dealing with a lot of weight? Thanks all.

 

i’m in the same boat man, what i’ve seen other people doing is going with the bilstien 5100 3” full kit and changing out the springs for OME 883 springs for the added front end weight...i’m considering that myself

 

I've heard mixed things about the ome nitrochargers and I kinda wanna stick with Billies also like Eibach a lot. However, I wanna use 700 ib coils like the ome 886 and I'm not sure they're recommended for use with the 5100s
