ok so i replaced the rears, had all 4 wheels road force balanced and got an alignment and things have improved greatly. i think i still feel maybe 5% of the vibration at over 80mph but i have to really pay attention to notice it.
maybe that's a speed range that's predisposed to vibration if there is any?
in any case it's not something that i will pursue for now, i have other suspension parts worn that need attention before i can be anal about a vibration that's virtually unnoticeable.
here are my before and after alignment results:
for some reason some actual values didnt print but the technician said they were in the green range.
can one of you suspension guys let me know if these values are good ? i asked them to go for the stock setup, i'm not trying to do anything fancy and the car will be daily driven with the occasional autocross.
thanks,
Cristian
