Slow 0-60, whats wrong?
Slow 0-60, whats wrong?
So I got a 2010 G37x Coupe with FI HFC,Takeda Long with 20s on it. Now my concern is I've done 3-4 0-60s already with DS mode and manual and average times im getting are between 6-6.2 seconds. I thought the stock coupe whether it be RWD or AWD got a 5.2-5.4? What am I doing wrong? 
No tune yet waiting to get a catback system and the Z1 plenum before I go ahead with the tune. Weird that upgrading from 18s to 20s would make me lose that much time off of stock. Wouldn't think the stocks are that much lighter. To be honest I felt the stocks were heavier.

Inertia. The weight of the wheel is spread out more on your 20s than stock 17s.
I think the prime example is an ice figure skaters when they do the spin move. When the skaters want to spin fast, they hold their arms closer to their body and slow down by extending their arms apart. The skater weights the same but speed can drastically changed by distributing the weight.
Also wider tires or sticky tires will create more rolling resistance

Reset your ecu the tranny is probably learned for a conservative driver. I actually reset my ecu every couple of weeks to get optimal response it makes a huge difference. Make sure the traction control is off too and brake torque to 1800 rpm's.

The wheels are slowing you down, tire sizes also make a difference. You could keep stock wheels and have the wrong size tires on and they would be a percentage slower than they should be. Plus, aren't the X models heavier than a standard coupe?

What are you using to time your car?
How much gas?
How many miles on your car?
Are you on level ground?
What is the weather/elevation like? Are you going against the wind?
Most of the published times you see in magazines are atmospherically corrected to a standard day at sea level, and are an average of runs in both directions.
Considering as others have said about the wheels, I don't think there is a real significant difference in the ranges you're quoting

A couple quick thoughts:
What are you using to time your car?
Stopwatch
How much gas?
20-25% left in tank
How many miles on your car?
Around 38,000
Are you on level ground?
Yes
What is the weather/elevation like? Are you going against the wind?
No wind, just a hot day.

Smaller wheels help with acceleration just by being smaller. Your car with 20's and 18's that weigh the same would be faster on the 18's. Bigger wheels, in a sense, change the gear ratio making your car accelerate slower but will have a slightly higher top speed. Smaller wheels have the opposite effect.
The 20's probably are a bit heavier, combine this with the slight change in torque multiplication and you're surely going to be slower than you would expect.
