Nice summary, Mr Smalls.
Sadly, because people read it in the Detroit News, and know a "test" was done by Eibach, 13% fuel savings from a 1 inch drop is now the "truth".
Carlos: that's exactly what they're doing - promoting the springs as a cost savings device. They even do the math for you on their site.
None of this deters me from wanting to lower the Firefly, but I'm not fool enough to expect a 13% (or even
a measurable, for that matter) improvement in fuel economy.
Edit: HA - I just noticed the Google ad on the bottom of the page now is for Eibach springs. Don't click!!
