I am somewhat puzzled. My TR3 with worm and pivot box responds quickly and
predictably to minimal inputs from the standard 16+ inch wheel in fast-
road/ track like turns. This using 165R15 radials, slightly lowered springs,
modern gas shocks and a vintage TR4 front anti sway bar. It also tracks just
fine in a stright line. (Though I do experience cowl shake between 55 and 65
mph, it disappears at 70.) Its hard for me to imagine how a much quicker
steering response would improve handling, as cornering does require a firm,
mindful grip. However I am finding that throttle input has as much if not
more effect on turn in and grip as steering.
