Hey, I can help with this! I've got a sport coupe and have been deciphering all the different kits out there. My two main options are Goodridge and StopTech (these are what my what my favorite vendor offers *cough* ZSpeedPerformance!).

Cars that came stock with the Akebono
In the front and rear, these cars come from the factory with rubber hose that connects to a hard line sticking out of the caliper. So the order is hard line at the fender > rubber hose (in the wheel well) > hard line starting near the knuckle that attaches the caliper.
The Goodridge kit provides SS lines that replace the stock rubber line only (i.e. the ss line goes from the hard line on the fender wall to the hard line that is attached the caliper). I believe the Z1 kit is the same, however I haven't looked into the Z1 option too much.
The StopTech kit provides an SS line that replaces the stock rubber line and the hard line out of the caliper. Further, the StopTech Kit uses a different routing and mounting method (no brass blocks, just clamps on the line). This line is a long stainless steel braided line with a few clamps on. The routing is not ideal in my opinion.

Cars that came with the base model brakes
In the front, these cars came with a rubber hose from the fender to the knuckle, a hard line on parts of the knuckle and a rubber line to the caliper. Rubber > Hard > Rubber > Caliper.
All the kits replace the entire front segment (rubber, hard, rubber) from the fender wall, to the caliper.
I am not sure of the routing for the Goodridge kit.
The StopTech kit provides a single SS line that replaces the entire segment. The routing isn't particularly nice.
In the rear, the factory setup is a rubber line from the fender to the caliper.
I am not sure what any of the kits do here.


My recommendations:
If your Akebono BBK comes with the hard line sticking out of the caliper, you should purchase the Goodridge sport kit for sedans (I recommend Goodridge as the routing is close to stock, and it makes use of the hard line; I'll be going this route soon).
If your Akebono BBK does not come with the hard line and you find it difficult to obtain these hard lines, you should buy a StopTech kit for the sport sedans. This will come with the right hardware to mount to the Akebono and the lines are long enough as to replace the hard line into the caliper.

Other notes:
If you buy a kit that goes directly to the caliper, be aware that the banjo bolt is different (length and perhaps threading too) on the stock and Akebono calipers. Akebono calipers require a shorter banjo bolt!

Hard line part numbers (from 2008 Sport Coupe, pricing from sewell parts):
46246-JK60B left front ($6)
46245-JK60B right front ($6)
46315-JL00A right rear ($7.76)
46316-JL00A left rear ($7.76)

Banjo Bolt sizes:
Akebono 17mm m10 1.0 banjo bolt
Base model 20.3mm m10 1.0 banjo bolt

Links/References:
-370z isntalling StopTech Lines, good pictures of the routing used I do not like how the lines are between the rotor and knuckle, I prefer them to be behind the knuckle (as per the stock design).
The FSM for the coupe, BR-21 has an overview of the piping layouts for the base/sport brake piping. It will help you understand what is being replaced.

The calipers I picked up do NOT have a hardline included - they were unfortunately cut during removal from donor vehicle. Therefore the StopTech SS kit will be the one I am going after. Looks like you can purchase both front and rear for ~$130.00 or so depending on where you shop.

This is the information I have gathered regarding application and part numbers:

FRONT (950.42012)
2009-2013 Nissan 370Z with standard and Sport brakes
2007-2008 Infiniti G35 Sedan with standard and Sport brakes
2009-2013 Infiniti G37 Sedan with standard and Sport brakes
2008-2013 Infiniti G37 Coupe with standard and Sport brakes
2011-2012 Infiniti G25 with standard and Sport brakes

REAR (950.42503)
2009-2013 Nissan 370Z with standard and Sport brakes
2007-2008 Infiniti G35 Sedan with standard and Sport brakes
2009-2013 Infiniti G37 Sedan with standard and Sport brakes
2008-2013 Infiniti G37 Coupe with standard and Sport brakes
2011-2012 Infiniti G25 with standard and Sport brakes

Help

I purchased Stoptech SS lines 5 years ago. I noticed my front driver side is chaffed from rubbing. I want to get Goodridge lines. My car is a 2009 Infiniti G37 sedan Journey. I added akebono sport brakes 5 years ago. The Goodridge lines use OEM mounting style brackets. My current Stoptech lines used clamps. They didn't require hard lines. My question is which Goodridge part number fits my vehicle. I picked up Goodridge 22054 cheap and trying to see if it will work on my car. I need to get the hardlines that go into the akebono calipers. Are the part numbers for the coupe the same for sedan. I contacted dealership and they wanted my VIN to confirm fit. However, my VIN doesn't show sport package as it is not how my car was built. Need help to make these lines fit my car. TIA

Hi JayDeePee,

I reviewed the parts.infinitiusa.com drawings for a 2009 G37 Sedan Sport (i.e. a vehicle that came with the Akebono brakes from the factory), the hard lines coming out of the Akebono calipers are the same part numbers as the coupes.
46246-JK60B left front ($6)
46245-JK60B right front ($6)
46315-JL00A right rear ($7.76)
46316-JL00A left rear ($7.76)

Goodridge 22054 is what I purchased for my coupe. My gut feeling is that it will fit. The service manual (BR-20) for a 2009 sedan shows similar mounting points for the OEM rubber hoses with standard or Akebono brakes.

Hope this helps!

Thanks for the info. Once I get my lines I'll check length with stock brake lines. Thank you once again.
