Well I'm a fan of the 2/1 , and still would love it , but I drive a lot sometimes at higher speeds , so I want to keep the handling there for now.
My 4R has taken me a lot of places with no offroad mods except bigger tires . So right now I want to keep the ride as close to the same . I drive 20-25 K per year and its my daily driver so at THIS point I just want to get a happy medium , between , look , stance , and practial function.
In my belief the more you alter something like height it takes away from handling ( by that I mean higher center of gravity ) also aero dynamics of the vehicle ( so will a leveling kit to a lesser extent extent ) and wear on drivetrain to some extent ( although not really documented on 4th gen. on the forum from what I've seen )
Dont get me wrong I think the 2/1 it a perfect size spacer lift and yeas I do get tempted , but I already have the 1" leveling kit so I'll put it on with my new rims and tires and see how it looks and drives and if I'm happy I'll leave it alone.
BUT , everyone here knows were never totally happy with our 4R's unless we are trying to modify something else .......

it's a given especially when you hang out on here.
edit: also if my xreas ever takes a crap it would pull it off and go to an ome set up with new springs and shocks.
