What did you do with your Z today IV

I don't know much about 370Z springs specifically but I'm guessing that these are progressive or dual-rate springs (less space between some coils, just by physical appearance.) These work out so that some of the coils end up compressed and touching under normal load and expand to keep the spring positioned when the springs are unloaded (like when you take it over some sweet jumps.)

If that is the case then the rubber is there so the springs don't clank when they compress and touch as the suspension is loaded/unloaded in regular driving (speed bumps, things like that.)
