Does the Tiger have any “weak” points that will come to light with increased horsepower? For example, I have heard that rear spring mountings are weak and will break under stress.


In preparing a Tiger for autocross or just for safety’s sake for street use, the front cross member welds should be reinforced, particularly around the shock towers. The CAT shop notes do a very good job of outlining these points to be reinforced. The reinforcement of all welds on the suspension mounting points is a good idea. These can fatigue and fracture over the years. It is also a good idea to reinforce the frame cross member around and underneath the openings for the Tiger exhaust pipes by welding 5/32″ thick plates to the three sides of the frame box. Cutout cardboard templates were required because it is a tricky geometry problem to get the plates the right shape.
