But I'm not going to remove it because it makes the car feel different in what I perceive to be a positive way.

I propose an experiment to lay this matter to rest. With the GrimmSpeed, it is the easiest thing in the world to take it on or off. Here is the outline of the experiment:
1. Someone with access to a track, a GrimmSpeed brace and a twin does a series of timed runs, all on the same day and under the same weather conditions. Same tires and driver, obviously.
2. Half of these runs are with the bar, and the other half are without. I suggest either 10 or 20 runs with each configuration. The more runs, the better the data set, but there will be a time constraint: how much time there is available to make the runs in the same day. 10 each is probably adequate, 20 each would be better.
3. Run a t-test (statistical test) to determine if there is any significant difference between these run times. Or if you prefer, a Chi-Squared test since there is basically only one variable (with the bar or without).
4. Question answered.
I don't have access to a track where I live. I know that many of the Cali types on the list do. What about it? Is anyone willing to step up? I am able to do the statistical analysis, since I have both R and SPSS on my computer at home. Hell, you could do this in Excel if you wanted to.
Any takers?
Science. What a concept!
