Thanks!!

Are you doing the gearing swap? If yes, please report back with your thoughts about how the car feels with the change.

Did you get the gears swapped out? Curious about your impressions.

Had the gears swapped out for a few months now and you definitely notice a difference in acceleration. The only issue I seem to have is when driving at normal speed the clutch seems to be a lot more sensitive to shift or atleast it’s harder to shift smoothly now

Hey thank you for that update! Do you have any increase in gear whine from the differential? I've kind of gotten used to the factory 3.73 gearing but still have the FRPP 4.09 kit sitting on a shelf.

There’s a very slight increase in gear whine but I only notice it with the exhaust valves closed and even then I can barely gear it

Good to know, thank you.
