Yes, I have the sport suspension and am sticking with my stock shocks. I don't understand how the shocks will wear out sooner with stiffer springs. The shocks will see less travel with stiffer springs for a given impact. On the rebound there will be increased force from the spring rebound but I can't see that destroying the shock unless you are maxing them out all the time. If this was an offroad vehicle I would be more concerned. Please let me know where my thinking is off.
Thanks.

 

After I install my 350z springs can I run 19" OEM coupe wheels with no rubbing issues??
