I've been reading all I can about the different lift options, to the point I'm getting confused. I've got a 2007 SR5 and ultimately would like to run 33" tires. I feel like that size has the best balance for my tastes. I'd also like to retain a slightly visible rake.
I've got a set of FJ springs and need new shocks so ordered the Bilstein 5100's front and rear (maybe I'll get them next month...). I'm sure I probably need more lift in the back to get the 33's under there comfortably. I was thinking along the lines of the 1.5" lift spacer from daystar.
With the order delay on the bilsteins it's got me thinking I might be better off just getting a complete 3" setup from somebody like toytec since it will all be designed to work together....... Not sure which way to go now am I over analyzing this or what?
there are def those much more knowledgeable than i but i'll share my experience because my 4r is my first lifted anything. in fact, i've always sought to go low baby (porsche 911 guy here). i know how things can get a bit daunting with all the crap info out there so let me distill it from a conservative setup vantage point that's worked out perfectly (factory like).
I have the full 5100 setup with OME rears which gets me the typical 2.5/1.5 lift. it sounds like the 5100s are on perpetual backorder. my 4x4 shop told me these 5100s were designed to be a drop in replacement with the stock 4R setup so not sure why people go with FJ springs. prob nothing wrong with it, but i didn't want to mix.
i run 265/65/18 BFG AT KOs on oem 18" wheels as u can see above. you're going to want to go higher than 2.5 for 33s, but understand there is a give/take here.
my mpg tanked from 17-18mpg to 13-14mpg mixed city/hwy driving. if i went w/ 33s, the additional weight and aero hit i couldn't tolerate as i'm already feeling a little guilty driving such a gas guzzling car close to stock H2 efficiency which is absolute dog sh!t. i immediately noticed the weight as well. i didn't like the feeling of accelerating slower though with the v8, the hit is not as bad as with the less torquey v6. as a speed guy, i have no desire to go heavier/bigger wheels for this reason.
but i wholeheartedly agree that 33s look better than 32s so to combat the less aggressive size, i decided to keep the running boards because it visually balances out the slightly shorter sidewall by making it look a bit lower than without RBs. in your case, i'd def go with the adjustable coilovers at 3" and whatever the dudes hererecommend for the rear. you do not want much more than 1.5" in the rear as that'll have way too much of a nascar/dragster rake which looks horrible.
so at the end of the day, i'm super happy with my results. i can cruise on the hwy on road trips as it's still lexus smooth, pound the urban pavement hittin up the nightlife all the while enjoying the rugged good looks of a nicely lifted truck that doesn't look overbaked.
good luck man! enjoy the process
