I've got 18" rims on my car right now and drove a buddy's that has the stock GE 16" rims on. Both of our cars are NA and slow. Well, I noticed his accelerated so much quicker and smoother than mine did. I figured it was because he has smaller rims on so there isn't as much of a rotating mass. These NAs are so slow that with 18s on it feels like I'm having to floor it just to get to 60 mph.
For a car making 180 rwhp, what difference is there if I downgrade rim and tire size from 18s to 16s? I'm just tired of not being able to accelerate comfortably. This car can't even get out of it's own way. It's also not comforting when like, minivans are passing you in traffic. Are my wheels too big for the NA?
I'm not going turbo for a while now and am just looking to make my ride more comfortable to drive and accelerate faster in the meantime. Also seems like these bigger wheels are killing my gas mileage.
Who knows a lot about this? Not looking to get flamed or ragged on, just lookin' for some advice.
