[MENTION=216416]Mutant138[/MENTION] a couple of notes that I had for you- I realize this process is sort of mind-numbing but I think you're on the right track and making sure the details are fine tuned to your liking will pay off on the back end.
Speaking of back ends, regarding the rear lift... yes I believe my 1.5" T13s got me the slight amount of additional rear lift I was after- I've seen the posts about them only yielding 1" also. Not sure what to say about that other than I'm still glad I did it the way I did. To my eyes the 1" spring that comes with the EPT kit has everyone using it with a very slight but identifiable amount of squat that mine does not have. Obviously everything is weight dependent and every 4R is a little different.
FWIW, I bought the components separately- front shocks, rear shocks, front springs, and then bought the T13s from Wheelers, so I'm not sitting on unused rear springs from the kit. Everything was the same price separately that it was together, but obviously the T13s were $40 more than the 1" Eibachs from the kit. Also, I confirmed with Wheeler's that the extended length of the rear shocks is the same as Bilstein 5100s (and Ryan @ Eibach), so putting more than 1" lift on wasn't going to cause damage. I wish Eibach would offer this kit with the option to choose your rear spring height.
Lastly, unless you absolutely need a ball joint UCA, check out the UCAs from Dobinsons- no greasing necessary, like OEM. Nothing against the other options but why grease of you don't need to? They're my next purchase.
