RCLT questions

Sup gents, I just put in an order for a RCLT kit for my second gen tacoma. Just curious for you guys that have one installed is what wheel offset are you guys running? I'm currently running a set of methods 17x9 with a 0 offset and 35s and I barely rub on the uca at full lock. My plan is to hopefully run 40s in the winter because deep snow and then switch out to 37/38 for the summer. Looking at how much bigger the spindle is and wider tires I'm guessing I will need to be in the -12 range.
Also what are you guys running for a rear axle? I'm about to pull the trigger on a fusion 9' with a +5.5" width increase to match the front.

 

For the rear cost wise Id go 14 bolt, not a dually so its wider or an AAM rear. 14 bolt has numerous widths and just get 6 lug hubs

 

This truck is a money pit already so I'm going all out....

 

I don't have a ton of free time so I love the idea of just being able to "bolt it in"
