s4 NA springs and TII springs are they different? they are both S4's are the setups or the spring rates any different at all my car got hit i need to replace the fender door and shock/spring...so i was wondering if s4 na stuff would be the same as my s4 turbos..... thanx!

 

S4 and S5 springs/shocks are interchangeable. The only thing that may slightly change are spring rates but I wouldnt worry much about it.
