Or as often? Or is the stress a result of the bad Ackerman angle in the Tiger, putting stress on the pins in a full; /html/tigers/2006-06/msg00192.html (7,954 bytes)

Here is why. The car has a weight distribution of about 50/50 and it weighs around 2500 pounds. That puts 1250 pounds on th; /html/tigers/2006-06/msg00195.html (10,834 bytes)

Materials all have a fatigue limit- stay below it and the part should last forever. The fatigue limit of aluminum is zero, as the pe; /html/tigers/2006-06/msg00196.html (8,532 bytes)

Less weight on the front also means that it willbe more responsive to steering forces so maybe more fun to boot. Unfortunate; /html/tigers/2006-06/msg00204.html (8,302 bytes)
