Also, with t-bar cars, depending on how tight you have the center screw it helps control forward bite and can be used as a more finite tuning aid. Looser is more forward bite and tighter is less forward bite. Similar to an Xray adjustable shock, I am looking to see if any companies make an adjustable center screw with settings? So I can say I have it on setting 1 (very loose) or setting 4 (very tight) so it's not a subjective setting, but more of an objective setting. I'm thinking this is probably too finite an adjustment that there probably isn't a part out there like this and probably not that marketable.
