This is from the GTR maintenance schedule. - please note the service interval. 1- 1000 mile service, then every 12 months thereafter. First ones are performed free of charge, then after the 3 year interval they are woven into the normal 6k service interval, similar to other cars. Of course if the user breaks stuff, then all bets are off.
If you have a source that says every 1500 miles, please provide it, because this is what I do for a living and any new information or resources help me do my job.

Measurement and adjustment of wheel alignment if needed (unladen with fuel and lubricants full, including tire pressure adjustment)
Note 1
Note 1: This vehicle is equipped with a high performance suspension. As the suspension components "break-in", the vehicle's
wheel alignment needs to be measured and adjusted by a GT-R certified dealer at the recommended intervals.
Engine settings (balancing of air flow for left and right banks) Note 2
Note 2: Each cylinder bank of this engine operates independently due to the vehicle's twin turbocharger design. Each side of the
engine must operate at the same level of performance. The power output of each bank must be checked and adjusted as necessary
by a GT-R certified NISSAN dealer.
Transmission settings Note 3
Note 3: The design of the clutch and transmission requires inspection and adjustment of the clutch and shift forks by a GT-R certified
NISSAN dealer at the recommended intervals. Depending on driving conditions, more frequent adjustments may be necessary
to help maximize vehicle performance.
These inspections are required at the following intervals: 1,000 miles, 12 months, 24 months and 36 months.
These inspections will be performed free of charge at a GT-R certified NISSAN dealer only. See your 2009 NISSAN GT-R Warranty
Information Booklet for details.
After the period of GT-R performance optimization services in the first three years, these items are included in the regular scheduled
maintenance.
*Repairs and adjustments involving part replacement, etc. determined to be necessary as a result of these inspections are performed
at the customer's expense.
*See your 2009 NISSAN GT-R Warranty Information Booklet for significant limitations, exclusions, and possible voiding of warranty
resulting from failure to have these necessary inspection, repairs and/or adjustments performed.
