ive been through three different lift kits since i purchased my 2013 trd off road in december:
1) bilstein 5100 with eibach coils notched to 1.75 and toytec aal in the rear.
2) icon extended travel 3.5 front coilovers with icon 2.5 rear shock and dakar leafs w/ overload in the rear.
3) pro comp basic drop bracket (icon suspension pending cause it never made it in time for install)
this is my take on the three that i have bought. the billies is a good budget option, you might be able to get away with 285s with some cutting of this and that. it basically looks like a stock height truck with anything you do.i always had people asking me if this was the stock height; kinda annoying lol. the icon setup definately sits higher than the billie setup, you definately can do 285s with very LIGHT trimming. i honestly could have gotten away without cutting it cause it just BARELY touched where i had to trim, probably due to the tread lugs on the mud terrain im using. the drop bracket lift is the head turner. people are gonna look at your sexy beast. even the lay people will know youre lifted. truck looks aggressive now. theres a big debate on wheeling with 6" truck--rest assure people do all the time. you will easily clear 285s. people go to 35s but im comfortable sticking with 33s.
5100- budget, stock looking, no spacers
icon w/dakar- little bit pricey, looks good, no spacers, cv angles in question
procomp- very pricey, (especially if you went with the icon, or other suspension to get rid of the barrel spacer in front and the procomp shock in the rear), head turner, basic=spacers, cv angles reset
