Any clue how much faster will you go after swapping your wheels? 0-100

As topic, How much faster will you go after swapping your wheels, for example from 17-19?Or 10lb different for each wheel?

Man, there are so many variables to consider here that it's starting to hurt my head. Wider is better than taller. Rotational mass play a huge roll. Tire compound and air pressure...

I don't think anyone can answer this question without extensive telemetry data on the scale of, like Sport Compact Car Magazine or higher.

You just gotta roll the dice, hope you made a smart pick on your wheel and tire combo. I'm gonning thru the exact same thing... 16x8.5+27 @ 16lbs or 17x9.5+15 @ 23lbs... Decisions decisions decisions...

I would think weight, and tire diamater would be the two largest variable.

Assuming your gearing could handle it, the shortest/widest tire, and lightest (and wide enough) wheel would be the fastest. assuming you could get a proper launch with out roasting the tires off.

diff ratio too! (assuming you go with something other than stock ratio)

i was gonna be a douche....but this one is just too easy, and im in a good mood today, so i think ill lay off

and why the hell would you worry about speed with 19's on a z33???

I thought the same thing.

Just curious....Anyway was thinking to get a CE28N on my car, and wondering would the difference be significant...

I assumed all the mechanicals stayed the same, just changing the wheels and tires.

As compared to what? And for that matter, what are the specs for the wheels you are looking at?

Like I said wheel weight and tire size will probably be the largest determining factor.

Lighter wheels have less rotational mass, and less unsprung weight. Which will help with not only acceleration, but deceleration and cornering as well.

A fried I race with dropped approximately 12 to 14 lbs from each wheel between a lighter weight wheel, and lighter tire, it may have been a shorter tire too, but I can't recall for sure. He said the difference was SIGNIFICANT.
