lift question

I have searched the archives and read several threads that cover some aspects but not my complete question. I have an 09 access cab TRD Offroad in the much faster speedway blue colour.

So far I have stayed clear of touching the suspension but now my warranty is up and my original tires are nearing replacement.

I bought a set of the Bushwacker flares and want to take advantage of the extra width the flares offer. If I went with a mild lift say like the Bilstein 5100/Eibach Toytec kit, what would I need to do to get the wheels safely out farther to fill those flares? WHat size tires would be best with this setup?

Vehicle has 3 leaf rear springs. I like a little rake. Should I get a leaf pack or AAL?

Thanks guys.

 

Wheel spacers.

 

Or new wheels

Wider tires help too
