No, I didn't measure it, but then agian it's not a racecar, it's a hot rod. I'm not a racer, I'm a regular car guy. Everyone seems to be chashing tenths... Anyway, the bumpsteer is not a problem with this setup, we have bad roads here in Norway, so I know. It has less bumpsteer than my 2013 Audi A7.
You have a very nice car!
What is your definition of bump steer?
This is a common subject of obscurity for many people and it would be helpful to hear which side you are coming from.
When I see a highly modified suspension with stacks of washers locating a tie rod end, I do tend to question the "it has less bump steer than a 2013 Audi" statement. It doesn't take much, at all, to induce bump steer in a suspension. Some people are luckier than others though!
