RE: ABT Upper Stress bar & misc susp. Stuff.



Heh, you think yours is bad? Try 205/40-16 Yoko A520's with a slightly more agressive wheel alignment and a smaller Momo steering wheel. You ABSOLUTELY MUST pay attention when driving on the street. It took some getting used to, but on the other hand, I don't have understeer problems on an autocross! :)
 
If you want to make your car more stable in a straight line, I'm pretty sure you would want to add more toe-in.

I've got a problem /w the steering/handling on "rippled" roads though.  You know, the roads that have sunken indents where heavy trucks have squished the pavement into ruts?  When changing lanes (at any speed) my scirocco intermittently madly resists turning, or lurches in the intended direction like a Ninnyhammer.  This sort of happens when cruising straight at regular speeds, and steering lightly/changing lanes.  I realize that this would sort of happen with any car, but I've driven a few different cars down the same strip of road and they don't do the funcky noodle all over the place.

There's your problem right there:  The 195s.  The wider the tire, the more likely the car's going to try to follow ruts.  With my 185/60-14s on Teardrops, I was absolutely fine.  As soon as the 195/50-15s went on, watch out!

Also, the added stiffness of the frame and the lowering of the car both will contribute to it.

You can mess with your alignment to lessen the tendency to wander, but I don't remember what the proper settings for it was -- I just deal with it. :)
