A few more additions to add:
Good:
Shifter has a 5-speed Rx-8 knob
Shifter has been shortened about 1" and rethreaded for better feel (not a short shifter)
All shifter bushings have been replaced:
-top and bottom cup bushings and springs
-groove bushing
-lower ball bushing (custom made Delrin piece made by a forum member) makes big difference! OE piece requires tailshaft removal, this piece slides in like s4 bushing
Not Good:
-A/C is not functional. Car was bought without equipment, so I do not have the components to reinstall. Convertibles don't need A/C
-Wiper switch has typical relay problem. Works on higher speed, does not work intermittently, will need new switch or relays replaced.
