How siginificant is it? Like how much of a difference does 18lb rims make vs. 22lb rims and so on?

Also, how much do the OEM 19" weigh?

Thanks in advance

 

i always wanted to know the same thing and also if aftermarket rims made any diffrance compaired to stock

 

Not real sure how much the coupe rims weigh... However for your other question, I have heard that losing seven pounds is about the same as gaining one horsepower.

 

Yea, I'm just trying to figure this out. I think it's different than the total weight, but I'm not sure. If it's total weight having 16 more lbs. really isn't going to matter to me.

 

it counts for bragging rights on the streets...in track applications its more of a "every ounce counts" issue.

Heavy wheels can be felt on the street, especially if your OEM wheels arent too heavy to begin with. You'll get sluggish starts and also see a decrease in braking if the wheels are heavy enough.

Also say your OEM 18" wheel and tire combo weights 45-lbs (25lb tire weight, 20lb wheels) and your 20" aftermarket set weights 55-lbs (25lb wheels, 30lb tires), you've added 40 extra pounds to your car, or more importantly 40lbs of extra rotational mass that you must now speed up or slow down.

for the everyday person, it may not matter and they're just happy they have cool wheels now, but for someone slightly concerned with perfomance it should be something worth keeping in mind.

 

OEM coupe 18s weigh about 24-26lbs. The oem Michelins weigh about 22-24 lbs.

When I went from my oem 17s (sedan non-sport) to the coupe 19s, it made a noticable difference. And these oem 19s are forged. Getting cast 19s or 20s would murder the acceleration.
