I have sports packaged g35 so it has 17 inch wheels

it is 5 spoke wheel and looks sporty
but it becomes dirty too fastly.
It even get dirty just after a day from carwash.
especially front wheels get more dirt than rear ones.

they soon turn their color silver to gray.
it makes car look dirty. i don't like it.

is it only my problem (because of my location) or all sports package wheels naturally easy to get dirty?

 

Brake dust. Change to a better pad.

 

My wife's 17" and my 18" don't get much dust at all. As far as I know, they're the factory branded pads.

 

^^You have an 05. This was a big problem on 03-04.

 

Brake pad is the problem?

 

yeah the brake dust is horrid, im gonna try to upgrade to brembos when my brakes need to be replaced

 

Hawks Ceramic low dust pads.

 

this is correct. Get hawks

 

reverse - this is common on 04 sport sedans. the brakes have great bite, but the brake dust generated is excessive. i have the same problem. just wash your wheels (and car) regularly, about once a week. try not to leave the brake dust on the wheels for too long.

 

also remember that your wheels are the closest thing to the ground besides your tires.

 

I've got an 04 G35x Sedan... the dust is real bad...

I use P21S wheel cleaner, then hit them with Poor Boys Wheel Wax.. they rinse off so much easier after that.. the wax is good for about a month, but it's worth the effort.. they don't get all nasty and black as quick and clean with a lot less effort too.

 

+1 try hawks. worked wonders here.
