You have Gen 2 Konis.....Which Konis?
-The 1999-2000.5 ACR Konis? Sounds like THESE
--The 1996.5-2002 Non ACR OE Konis?
---The MoPar Perf SCCA T1 Konis? Could be THESE
The answers to the above, coupled with your driving venues, aero, and tires will dictate best spring rates. As far as best deal? Fair price, coupled with good, solid Viper advice? I bet a couple of your club vendors would be worth a look ...... even if they might be $10 higher or so than flea-bayers who KNOW NOTHING and certainly not that there are multiple Konis on Vipers !
