I love the look of the 9" wheels. Did you go up a tyre size (225) ?
Thanks Enzo.
Hi, yep 225s

I join in congratulations! Have always loved the C4, wonderful understated car. I had oversize 15" wheels on my 365GTC, the prototype Campagnolo star mag wheels, first on a road Ferrari. I love that color - looks like blu Pozzi.

You will (may) notice two differences, possibly a third: with larger circumference tires, you've changed to a higher final drive ratio that will slightly affect acceleration negatively and fuel consumption positively. Also on full steering lock you may (or may not) have a bit of tire scraping wheel well. Since you're not racing ;-) all very little price to pay for a significant enhancement of the 'stance' of the car, seriously good-looking! Again, congrats!

Seth- I bet he only put 225/70 15s on the rear. Difference in diameter is only 27.40"-26.85"=0.55" which is 2.0% larger than OEM.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.

Yes, that is the standard fit tyre for the 9" wheels
