For those of you with 20" Rims

IMO, unless you are autocrossing, go with what looks good to you.
BTW ... you can easily chop more rotating mass by going to a BBK!

Big brake kits usually utilize aluminum hats with 2 piece rotors vs one piece all steel rotor/hat combination. This allows for lighter rotating mass and unsprung weight.
This is a very expensive upgrade just to save some weight.

Would it be worth the 2500 or 5000 (assuming we're looking at both front and back) just to reduce the weight the extra wheel size produces?

They'll have data for the 2007 G35 shortly.

DH how would you rate the acceleration/braking ride and drive performance with the current setup you have now vs how it was stock?
And what were some of the major differences you noticed when you first drove with this setup vs how it was before? Can I ask you one more question....how is your gas mileage compared to stock like did it drop, did it go up or stay about the same?

braking is noticeably less too, it takes more effort to slow the car down.
ride it a little bit more rough, you can really feel every little pebble in the road but it seems to take pot holes in stride.
gas mileage went down maybe 0.5mpg.
all in all performance, ride and economy were sacrificed for looks.

i would assume these are the forged wheels people have been raving about as far as being light etc? Do you know their weight off hand the website doesn't have it listed.
BTW Tirerack has your 285/30 BFG tires weighing around 31 lbs a piece. Don't know if it helps but just wanted to put that out there
