So when you say "bend down"....  in essence... it has more to do with making it
go lower,  than to change the shape, right?    Since a tech-pass was your main
issue, it was more about having it not appear to hang very low during a tech
check?

I could see how that might still apply for racing, but also, on the street...
it would be great that there's more clearance at low speed, in the city, etc...
and that it would lower itself when on the highway at high speed.   Trick.
