I have been thinking about changing to 410 gears. Was hoping someone with them could tell me how you like them. Seems like I should be able to use 6th gear more on the highway instead of 5th.Around town it seems like I hardly ever get out of 3rd with the stock gears. What I'm wondering is how bad will my mileage suffer under normal driving if I switch to 410's. As always thank you for your comments.
