Yes springs wear out. I have never seen a specification for the spring
rate for a TR3A. I bought new springs from TRF but they could/would not
tell me the spring rate.
If you know the spring rate you can test your springs with a tool called
a spring compressor. It is a manually operated press with a guage on
it. With the spring in the compressor you compress it one inch and take
a reading to see what the spring rate is.
If the spring does not meet spec then replace it. If your springs are
original and you have the front end apart replace the springs on general
principals.
TRF has two sets of springs available. In their catalogue the stock set
is notated as not needing the aluminum spacers. The competition set is
notated as needing the spacers. When you buy the competition set Dave
will tell you not to use the spacers. Do not believe him. If you
remove the spacers from the car with the competition springs you will
lower your front ride height by an inch and a quarter. This will affect
ride and handling. You may like the change but if you don't you have to
do the spring removal and reinstall the spacers.
