I think the biggest improvement is the steering rack change. I don’t understand Ackerman angles but with this change the steering is much more responsive, the car doesn’t drift on the road and it feels safe. Another significant improvement was using Dale’s rear leaf springs and removing the panhard rod. With 7" of rubber on the road, these changes, new front springs and new Konis all around this Tiger feels like it’s on rails.
Installing the new leaf springs does drop the rear end some so I did have to prune the inside fender lip a little at a time to eliminate tire scrubbing. I recommend these modifications to anyone. It’s truly a fun car to drive. Don’t forget about the positraction – incredible. Bruce
