Personally, I don't any color of IS300's are bad. I like them all. I would drive any colored one, but I ended up getting the color I wanted
(silver). Anyhow, I like the lowered look with the new springs. How much did you drop it, and did you replace the shocks too?
Don't lower springs put more stress on your stock shocks though? I would like to get mine dropped about an inch and half too, but I'm worried about how it will affect my warranty, and whether or not it will wear out my suspension.
