cool. i too am running LM60's but on my G35C. this season was the first time in 8 yrs of ownership i drove her through deep snow, salt, and ice.
it was kind of a test of deciding whether to keep her or sell her when spring comes around.
my 04 weighs about 3600lbs+ and gearing is taller in 1st and 2nd, and power is rated 280hp at the crank vs 330+ so, much easier to handle vs the Z in slippery conditions.
anyway, i felt so confident driving the G in the snow with LM60's i think i will end up keeping my G longer.
