S650 R&P - 3.55 v 3.73 v 4.09

A few people here have done it. Please chime in.

What's are shops getting to change the R&P?

I went from 3:15 to 3:55 but I did complete differential. Local dealer did the work. About $2300 all in.

Do you feel a significant difference in acceleration or fuel efficiency?
