Well I made a change I didn't initially think I would do. I ended up buying a set of TRD lowering springs and replaced the Tanabe's that I installed before. The Tanabe's dropped the ride height 2 inches, which I liked, but on some sections (bumps or dips) of certain roads in my daily commute, the tires would briefly rub on the inner fender
liner. If the tire/wheel combo was "tucked" (more offset?) closer in to the car, there would not have been any tire rub. However, with my choice of rims, I had no choice in the offset.
After further research I found out that the spring rate on the Tanabe's are linear and the TRD's are progressive. Plus the TRD's don't lower the car quite as much. More like an inch and a half vs. two inches. That slight increase in ride height plus the progressive spring rate has eliminated any tire rub! I am
VERY happy with the TRD springs. Hind sight is 20/20, but I should have bought the TRD springs to begin with. Live and learn.
The Tanabe's work quite well and are a good set of springs, but with my particular offset and the width of the tire/rim package I bought, they were not a perfect match for my car. (Anyone interested in a set of "like new" Tanabe DF210 lowering springs?
