alot of bilstein 5100 questions.. help lol

ive been thinking about this for a while.. with the winter coming and cash flowing in from selling one of my jet ski i think i might do it now.. just wanted some opionons

im looking at the kit offered by toytec.. bilstein 5100s all around with the aal in the rear..

so first question.. they offer a 1.5 and a 2 in aal.. i have stock suspension now.. i DO NOT have the tsb leafs.. so i plan on going 2.5 lift with the front bilsteins.. so im thinking the 2 in aal in the rear would bring it level.. correct??
here is the kit
389 plus 80 for the aal seems reasonable.. anyone get there setup cheaper anywhere else??

now ive read alot about the 5100s and correct me if im wrong it seems to be the easiest and simpleist way to add one or two inches.. i do not do alot of offroading.. i do some mild trails when i go camping/dirtbiking snowmobiling, but i do a ton of towing and hauling..so im not looking at building a huge lifted truck.. just trying to enhance the stance, while trying to keep the back from sagging under load so much.. is this route my best bet..

 

A 1.5" AAL will probably make the truck sit level, and the 2" would give you just a little bit of rake.

 

I have that exact same set up, the 2" aal will give you rake.

 

thanks guys

 

Question: truck is an 05 Tacoma 4x4 v6

My 5100's are on the way, with them set at 1.75 to level my truck out what is the biggest tire I can get on my stock 16 inch wheels to fit?

If i were to add a rear aal say 2 inches and billys set at 2.5 what size tire then.
