COMPOSITE LEAF SPRINGS for MGA -- RS-202

Now this one I rather like, for a number of reasons. For no holds barred competition there WILL be some advantage to using composite leaf springs, but this may also put your car into a different racing class. Read the rule book first.

For street use there can also be significant improvement in road handling and in ride comfort. It is not often that I get to put both of those improvements in the same sentence. This is a direct result of a HUGE decrease in unsprung weight. A pair of original steel leaf springs on the MGA weigh about 40 pounds. A pair of composite leaf springs will weigh about 10 pounds. Removing most of 30 pounds from the rear axle assembly will reduce rear axle tramp considerably.

Less unsprung weight means quicker response to a bump and less energy being transmitted into the frame of the car (less bump in your seat). Less mass also allows the shock absorbers to catch the upward motion quicker with less travel so the springs can return the tires to the ground much sooner. Tire compliance, keeping the tires in contact with the road, is the holy grail of "sticktion" (continuous grip).

I have not had the opportunity (money) to try these things myself, but if you are so inclined, you can buy composite leaf springs for your MGA and find full instructions on Doug Jackson's British Automotive web site.

As always, if anyone without a vested interest in selling these parts has used them, I would like to have a user report.
