This post contains the wheel alignment specs for the various M models.

Also note that the 2006 M35 AWD model has different alignment specifications than the non-AWD M35 and M45.

Of course, remember to set wheel alignment with a full tank of gas, and items like spare tire, tools, etc. are all in their correct places in the trunk. No other unladen weight either - i.e., remove all the other "stuff" from the inside and the trunk!

Note that our resident Infiniti expert, Q45tech, also says the following (quote mildly edited):

Q45tech wrote:YOU OR YOUR WEIGHT MUST BE IN DRIVERS SEAT! Otherwise the alignment will be off when you get in the car! Assuming you drive alone. If you always have a passenger, the same loading situation must be maintained during alignment proceedure ... assuming you care about perfection.

Your weight [150 -300 pounds] in the seat will lower the drivers side by 0.2-0.4" which will change the drivers side camber by 0.16-0.32 degrees.

Of course, the above applies to the alignment, not the wheel arch height data!

This post contains information on the transmission and gear ratios of the various M models.

This post contains information on the final drive ratios and related information on the various M models.

1. The OEM 2006 M35/45 wheels have a very high offset and cannot be used on other Infiniti models (using spacers is not recommended!)
2. The OEM 2003/2004 M45 wheels can be used on other Infiniti models since the offset is compatible with many of them.
3. The NISSAN Matic J Automatic Transmission Fluid (now NISSAN Matic-S Automatic Transmission Fluid) is required for the Infiniti transmission warranty to remain in force. Do not substitute any other ATF.
