Question 02 Tundra Lift and INFO (sorry newbie)

[Pancakepete]

02 Tundra ext. cab 4x4 SR5. 4.7L
I have been searching all over the site and wondering from what people have done and why?

I purchased:
6" RCD
20"x10"-4.56 BS. xd Rockstars chrome w/ 35x13.50" procomps
edelbrock single to dual cat back
k&n intake.


I see alot of people that run 35" with rcd also do the 3" body lift.
I am wondering why this is?
ANd how can you run 2 steering extensions if you do so ?

Also I see on alot of pics that people run 35s that look wider than 12.50.

I am wondering what problems with only running the 6"rcd.
The lift at the 6" setting also looks like it sags in the rear ?

Im kind of a dear in the headlights here. Thank you for any help.
