Rob, sorry, not making my point well. Springs don't go soft, their material changes and thus their spring rate. Usually their free height reduces, and their rate changes - both affect the handling.
Alfonzo - we need to buy tickets to watch anyone trying to do that. It would be better entertainment than watching them race!!
Just fire up this torch, hold it near the spring... Oh s*!t, I;ve melted it!!
Like Rob says, springs are so cheap, so easy to fit - so buy some!
