The OP reported from the first post that he got 2.3" (#5) on a stock front end. I also recall reading others getting less lift than advertised.
I also recall reading some folks getting more than 2" with 2721. Seems like the lift estimates are not perfect. I'm happy i ended up in the lower range.
What's your current rake?
My current rake is about 1.25" (Front 19.25", Rear 20.5"). This is all stock with a Prinsu rack and a ~full tank of gas. I found a few more posts along with Slee that 2721 on a stock LC would gain 2-2.25". So I am thinking perch 5 with a 2.3-2.5" lift would reduce or maintain the current rake. I would prefer the stance to be more even but don't want to put too much of a load on the CV joints with even a higher lift from perch 6. Thank you all for suggestions.
