Upgrade Double Check

Hey everyone, after many long nights of research, I finally have a good idea of how I want to modify my new Jeep. Although I feel like I have a good grasp on everything, I am no expert. I am looking for someone to look over my list to check for anything that does not seem right, things I should be worried about, anything els I may be missing or should be adding.

2012 JKU

TeraFlex 2.5" Lift (with coils)
Rancho RS9000XL Shocks
Goodyear Wrangler DuraTrac 305/70R16
Black Rock Series 997 Type 8 Wheel 5x5 16x8 Size & 4.25" Backspacing

My second question is which Rancho Shocks are the proper ones for my lift. I contacted Quadratec and they pointed me to these shocks which seem correct.
0-2" lift front (Extended: 21.75" Collapsed: 14")
2" rear shocks (Extended: 22.63" Collapsed: 14.5")

Although through my research it shows that Rancho has a 2.5"-3" shock but does not show the extended and collapsed numbers. Links below:
Front
Rear

Thanks for any and all input.

I chose 16" because they are a little cheaper, I like the way they look, and offer more sidewall (as little as that is). I can be easily swayed between the two if you have any pros/cons yourself.

I have the Rancho shocks and the ones rancho will recommend for your lift are the RS999329 and they are 15.6 compressed to 25.28 extended. The teraflex shocks I had, if they were really 2.5" lift shocks were longer and closer to the rancho rs999331 which is 16.6-27.32".

Those were the front numbers. I kind of think the shocks rancho specs for lifts are shorter than they need to be, I am not sure why they do this? The rancho rep used to be on here a bit and answer questions. Maybe my teraflex shocks were not the correct ones for the 2.5" lift, I don't know.

I run 15" wheels and like them. However, if I were to do it all again from day one I would have gone with 17" wheels. There are more tire options and you will be able to do a big brake kit later on if you feel you want it and you will have an easier time doing a steering and tie rod flip if you ever choose to do so.

However, with the 15's my tires are way cheaper than 17's. I wouldn't do 16's, it seems like they are going out of style too and it will become harder to find tires.

I liked my 2.5" teraflex coils. You should be happy with it.

x2 on the 17" vs 16" wheel. Lots of tire choices for 17" wheels. 15s were great for our TJ but won't fit without some modification on the JK. The big break kit option is nice too. I haven't gone that route yet but it is nice to have the option in the future.
