The stillen is the same size (roughly) as the SE/SR sway bar but is solid and not hollow like the OEM. The RL bar is also solid, a stronger material, larger than the stillen, and adjustable. Both will work well for your application and you can't go wrong with either as far a an upgrade goes. But the RL will perform better and I have yet to receive a complaint that the RL swaybar created an uncomfortable ride.
Hope that helps you decide
