used a protractor set at 18 degrees for the correct angle. Somebody correct me if i'm wrong as that's what I read is the best angle to use.
and installed them.

This was just a first try as I soon found out this is a bad spot as the rear hatch hits them. Also not to sure there current location is effective as its after the break for the rear hatch and I may move them forward. Also may up the size to 1"Hx2"L. but this is what I had lying around.
noticeable changes? Not really but the rear end did seem more stable when cornering at speed.

Damn drive a yaris in md and have a long commute to fabricate...we must be brothers.
