I have the toytec boss w/ 600lb coils up front & OME 890s in the rear on a stock set up and it rides really well as my DD. It feels slightly stiffer (in a good way) compared to the factory suspension. Toytec also offers the 550lb front coils if you wanted something a little softer. When I called them, they told me that the 550 coils would feel closer to how the factory suspension feels and the 600 would be a little stiffer but would handle turns slightly better & have less body roll & I'd have to say they were pretty accurate in how they described it. I have driven a 3rd gen with the toytec ultimate set up & I couldn't tell the difference. The ultimate I drove had the same front and rear coils that I have but don't remember which shocks they had in the rear. I went with the boss mainly bc toytec said it would have a slightly better street ride then the ultimate. But like I said, I couldn't tell a difference between the two. The ultimate is a little cheaper so you may want to take that into consideration.
