A friend of mine had a Tiger he did up for racing. The chosen race track for its debut was in Calgary. Nice track, gone now, except for a concrete wall lining one corner. Not a ten-tenths course by any means. Out he goes and sets a blistering pace on his first lap. By the third lap, he's making a gap. Charging down the straight towards the concrete wall and the pedal hits the floor at his braking point. Somehow he lived and saved the car. Towed it home and fit uprated brakes but was never as fast again.
I worked on a mint, 20K mile Tiger II (the one with a single Chrysler penta-star emblem on the side of there RH front fender). The brakes were scary awful. You would hit the pedal and it was not only rock hard and unresponsive, the pedal would actually rise slightly! Stripped the booster and discovered that one valve had been put in backwards such that line back to the master cylinder received the assist, bizarre. Seemed to have been that way from the factory. Brakes were much, much better afterwards. Still stock Tiger not-great but at least they worked well for a few stops in a row.
