New To TW NEED TOYTEC HELP!!!!!!

I just got a 13 Tacoma Sport DC and want to get a 3 in Toytec Ultimate kit because I'm want to put some 275/70/ 18 Trail Grapplers on it. But I'm new to the lifting process and when I went to purchase the kit it has options such as
Front coilover options
Front coil spring rate
Front diff drop kit
Spanner wrench for adjustment
Rear Shock options
Add adjustable upper control arms
Rear Lift Options
Do these come preset or what should I choose for each option.
Thank You In Advance

 

They come set but you should just buy the coilovers from them and then get 5160 shocks for the rear shocks plus go with icon upper control arms

 

If you really don't know what you're doing, I would suggest you call Toytec and have them help you. I wouldn't go in blind and spend all that money hoping you got the right stuff. You need to pick what you want for each of those options, hence the drop down menus.

For the front coils just pick your color, if you don't plan on adding a plate bumper and winch get the lower spring rate as well. If you plan on off roading, I would upgrade the CS047 OME Dakar rear leafs. The new upper control arms are a good idea. You may have issues getting a good alignment if you don't get them. The differential drop is a waste....don't get it.
