do you guys know if there is a difference between the 09 g37s rear differential and the IPL REAR? I need to replace mine and there is one close by I want to pick up but want to make sure it will work before I pull the trigger because I see on driveshaftshop.com the upgrades say "except IPL" so I'm worried now there is a difference

 

The IPL is a coupe, so if you have a coupe you should be alright. The extra length of the sedan means it uses a longer driveshaft which may be why the site shows the exception.

 

The differentials are compatible sedan, coupe etc. I can put a 08 g37 S vlsd in my 7 speed auto sedan and be okay. I'm pretty sure the differential on the ipl is the same as the diff in the g37s coupe. I think compatibility will be fine

 

Yep, same part numbers, all the same.

 

Just make sure you match auto to auto and manual to manual otherwise you will need to change the flange

 

Anyone know the weight difference between the lsd and standard?

 

I couldn't tell you exactly, I cant imagine much if any. But, even if the LSD weighed 50lbs more, its well worth it.

 

what do you mean change the flange?

look at the driveshaft flange with AT vs MT
