The reduction in that lift and dive is where bigger bars give up performance at the drag strip. However, they are much more consistent in the e.t. department and are a significant improvement in street manners. I think Dr Charles will find the 1.03 bars for his dual purpose car will give me a much better mannered street car but will cost him some in the ultimate e.t. at the track. IMO, a fair trade off for something that is 90% street orientated.
