How many of you guys that bought the swaybar and notice significant improvements, are running light trucks? Like with a payload of over 1600 pounds? I don't notice anything that makes me anxious while driving mine, but I have a light truck with more than 1700 pounds payload.
I have the Bighorn level 2 with payload of 1749. I added the OEM sidesteps and my tires were about 13 lbs heavier each (Falken retail version of the ATW3's). So a little more weight added. I also have the 6'4 bed.
I think the following have added to my "feeling" the sway bar results more than others---
1. I take curves (and scrutinize them) most likely harder than the average bear. Autocross days allowed me opportunity to understand how a few PSI (tires) played a part in the curve and handling of vehicle(BMW at the time). When I get the opportunity of no other vehicles around and a curve is involved; I flashback and enjoy hitting the curve hard, make a smooth weight transition through the curve and holding the line.
2. Obviously the Sway bar itself and improvement over stock feeling
3. Have to say my tires felt grippier going around the curves over the stock even before getting sway bar--going from the stock all season Nexen to the all-terrain Falkens (I have ran both the Falkens and Nexen on my BMW trying many tires) You could add tire pressure too as that plays a part in the "feel" (along with smoother roads here in Florida)
4. The wheel spacers adding little more width over stock feeling (1.5" front, 2.0" rears)
I think the combination of my factors contribute to my butt-o-meter feeling happier through the curves.
A bit longer, a bit wider, a bit grippier, and much stiffer sway bar = better handling than stock and less roll/lean.
