I installed a Speed Steering Dampner today from Magic Racing. I used the same style dampner on my EX for years with great success. I raced this past weekend in New York, and I wished the whole two hours I had a dampner. I ended up 4th out of 71 riders with my Z for its First Race Ever, and the competition wasn't shabby, Chris Borich (Pro #5) Won the Race. I will be trying out the dampner in PA this weekend and I will post how well it does.
