Precision MotorwerksPrecision Motorwerks makes replacement FPR and Dampers that should work on the 911 as they are the same for the 928. One thing to keep in mind with the aftermarket dampers is that most modern cars are sequential injection instead of batch fire like our older Porsches. Batch fire requires a larger damper volume then sequential. most of the drop in units do not have the volume capacity to support it. the ones from Precision were specifically designed for our batch fire systems. You may have to call or email to get the details as his website is very limited.
