someone told me that coasting in neutral at higher speeds (80mph) is bad for your car. is coasting in neutral bad and should you downshift instead? one guy said that coasting in neutral wears out your brakes too much. what do you guys say?

well I think what he means by 'bad' is that when u put it back 'in gear' you might be putting lots of 'pressure' on the tranny at one time. but I dont see there being a problem if ur cruising...and the thing about the brakes? thats only if ur stopping right? u can down shift when ur slowing down, but that also makes the tranny work a little harder...

what he said:D basically the RPM is dropped back to idle, but the car's clutch is not engaged so the only thing that is moving the car is it's own momentum (sp?) if you want to get back into gear, try to rev match the car.

ahh i c. too much pressure on the transmission. another thing. my friend said that rev-matching wears out your clutch. i thought it did the exact opposite. what gives?

Where did your friend get his information? I think he needs to check it again.

you're both wrong, it saves wear on the synchros which do exactly what rev matching does, but physcially on the gears and they wear under extreme shifting conditions like what you mentioned and others. synchros are what prevent the need for double clutching like old cars did aka rev matching.
