Rear Suspension Spring Rates

If you want to play around with the suspension of your 33, the first thing you will probably change is the springs. To get some idea of how the standard car is set up or to find a standard Alfa spring that can do the job, here is a list of the standard spring specs for the rear of the 33.


If you find any errors, or have any extra figures to add then please mail me.
