Drivers' Rear shock was leaking fluid so I started to investigate.  Once I removed the boot carpet and floor I was able to access the top of the shocks.

I removed both coilovers and the shock was completly empty of fluid and pressure.   The passenger side has minor leaks starting.

decided to replace both as they were sealed units and not rebuildable. 

Decided on QA1 DS502 with 17 inches extended, 14.5 ride and 11.6 compressed.  With the 125lb spring, this should be more effective than the stock 104 lb with 12"x 2.5" spring

18 position adjustable for compression and rebound. 


ordered from Summit Racing

Installed and adjusted to softest setting.   Next year I may select a softer spring that is 10" long to allow for additional adjustment.  possibly 115lb for 10" spring
