Adjusting front roll center with slugs

Has anyone done this at the track and can tell a difference?

Are you talking about moving the upper control arm?

Are you talking about moving the upper control arm?

Yes, either side or both.

Not with the slug setup, but yes. It is going to depend on how much you move it as to how noticeable it is.

Are you talking just the heighth and/or left to right?

Bill Frye told me years ago, he could adjust his 5" up or down, but during testing, he couldn't tell a difference. Of course, that was with the old style setups.

I have only adjusted up/down at the track. In/out during the week in the shop.

I would disagree with Bill Frye big time with modern setups.

The camber curve change will have a greater influence than the kinemetic roll center height. As one of my friends on another message board said:
"After many years of observation and participation, I submit the following hypothesis:
Of every subject discussed on racing message boards, "roll centers" have the highest ratio of words typed to actual importance to lap times of a vehicle."
