I have a 2001 Tacoma Extra Cab TRD with the V6 and 5-speed with the 3" Cornfed lift. The kit comes with everything you'll need, spacers, add-a-leafs, diff drop kit and all the necessary brake adapters. The truck rides a little stiffer, similar to a 3/4 ton full size, with the kit. I also installed Daystar greasable shackles on the truck, these things make a significant difference in the ride, they are well worth the $$$. Engine power suffers a little bit, I really only noticed the loss of power at top end, i.e. going up a long steep hill at 65 in fourth gear floored, you will lose some speed. I'm running 285-75R/16 (roughly 33x10.5) Bridgestone MT's on 16x8 Wheelers Off Road Steelies with 3.75" back spacing; the front tires rub on the back of the fender flare under any kind of suspension compression while turning. I wouldn't recomend 33's with only 3" of lift, the rubbing is really annoying, go with 32's, or you can do as I am, run the 3" suspension kit with a 2" body lift and have plenty of clearance for the 33's. All in all, I'm much happier with the Tacoma lifted than in stock configuration. As for options, BLOCKS SUCK, I had them in my Tacoma for a couple months and didn't like the sh!tty ride; add-a-leafs and shackles increase your load capacity and provide a better ride. Coilovers are very sweet, they giv you great ride and provide 3" of lift for the front of the truck, If you can afford them, buy them, I highly doubt you would regret it. If the money is available the ultimate is the Fabtech or Trailmaster 6" lifts (roughly $1500-$1800), plenty of clearance for 33's (35's will rub), you still retain a lot of the stock suspension parts so the ride is pretty good.
