Hi all,
I got a certified pre-owned 2003 G35 RWD (w/ premium & aero package) this past summer. The car has been great to drive. I recently put Blizzaks WS-50 on the car (205/65/16" - went with a narrower profile that fit my car). 2 cars ago, I used to drive a RWD Isuzu Amigo that was really light in the trunk. I weighed down the back with a ton of weight.
On the G35, I currently have 200lbs (4 bags of sand). Is this too much or little?

I got clobbered last week with 6 inches of snow and the G35 did really well. Traction light came on for a nano-second coming up a hill. I live in a very hilly area in Pittsburgh that gets mediocre attention from the PennDot salt crews. Last night, I hit a little black ice and the SLIP light came on again so I want to make sure that the back end is weighed down sufficiently.
Thanks for your help.
