Difference of wheel size

[whitebeach]

Just trying to get some advice on wheel size for an E85. What is the difference in handling etc between 16,17 or 18" wheels?

Thanks

18 look better and Falken tyres transform the ride! Every one says it and its true - by ditching the run flats my Z has been transformed!

Yesterday Had Goodyear Eagle F1s 18 fitted to each corner, totally different ride, worth every penny. My run flat rear are up for grabs though.

All of the above - 18" with non run flats

Aside looks and cornering performance being the best on 18's the downside is that they make the suspension firmer and more 'crashy'. Not an issue for most drivers of sports cars, but a factor.
The bigger the tyres the more expensive too and can increase rotational mass (reduced acceleration, impaired braking, etc.) but you'd probably never even notice it.
