I heard someone say when your trying to pass someone in a stick shift like on a highway you need to drop down a gear to get high RMPs to pass him.Is this the best way?I'm new to the manual transmissions thanks

Depends on what kind of car you're driving. If it has enough torque to pull you past the other vehicle in a higher gear then you don't need to down shift.

But if you're driving a little car with a little motor, odds are you'll probably have to bring it down a gear... or in some cases two gears to get enough grunt to get around.

The best way to pass someone with my truck and have a good speed, time my rpms, get a medium high rpm and shift up as I pass them. It's about getting your rpms up first.

let's not forget that road situation also plays a part.
How fast you're going, how fast they're going, how fast traffic around you is, whta car you're driving, what car they're driving, etc.

ok on a multi lane highway...i dont worry bout downshifting.

as for single lane dashed lines... i down shift my stealth and go, shift as i go by then get infront of him.

it just really depends on the amount of tq u have and where ur rpm is
