I have a 2003 G35 Coupe with 6-speed manual transmission, 18" rims, sport package and Brembo brakes.

Unlike most of you crazies who feel the need to upsize to a 20 or 21 inch rim, I would actually like to go down in rim size.

A smaller rim with a higher-profile tire will ride better and be quieter than the stock 18" rims and Michelin Pilot tires which, quite frankly, are killing me. They're too hard and noisy for daily driving.

Also, large rims add significant rotational mass to the drivetrain. When the G35 Coupe was first released, an article appeared in Sport Compact Car magazine in which they attempted to increase the performance with a few tweaks. They were able to shave a few tenth's off the car's quarter-mile time by going down a wheel size. Large rims may look "bling", but they actually make you slow er.

On other G35 sites I was able to find two people who mentioned that they found 17" rims which will clear the Brembo brake calipers. These people were using:

17" Black Racing Pro N1
17" Eagle Alloy, Style #196

I'm having difficulty finding these brands or models at local tire shops.

Does anyone have any experience using 17" rims on a 2003/2004 Coupe with Brembo Brakes? Know of any particular brands/models that will fit correctly?

 

Tirerack sells the Kosei K1 TS. Very light weight.
Also, the 5zigen fn01r-c is pretty light and priced right.
