I own a very low mileage 2006 g35 coupe and as the topic states I'm doing a swap for my engine and trans to multiply my power. As of now I have the engine the trans and full swap kits/adapters for both. I'm getting stuck when it comes down to my axles and rear end/differential. Which rear end would be my best bet to support the most power? And also any advice is appreciated

 

Any help?
