Totally different animal, but I just installed a 3" OME suspension from Kurt on our FJ80 and it's a pretty impressive difference compared to stock. The suspension is more firm, really feels like the SUV is 'planted' both on and offroad. We actually jumped it tonight...
There's a
perfect roller out past Glade Park, our tires barely left the ground, but we were weightless for a bit... the suspension felt very controlled as the 7k pound 4x4 came back down, it was honestly impressive.
Like Kurt said, you can pick out the optimal spring rate package based on how you use your vehicle and where you have added weight with winches, aftermarket bumpers, etc. The coils we picked out are built for added capacity, so even when loaded up for camping, it should ride well.
I also picked up a 2.5" OME suspension for Catherines '03 V8 4Runner, which the front suspension should be pretty similar to your Tacoma. I haven't had time to install it yet, but if I get mine done soon, I can post up the impressions of before and after.
