Does anyone know if I can change out the small OEM brakes that come with the sport model for the OEM Akebono found on non-S models? I am assuming that it would be a straight replacement, removing the old caliper assembly and replacing it with the new caliper and pads. Another question I have includes; will the rotors I have now (14) work until I can replace them with sloted/drilled rotors?

 

Ummmmmmm....what??!

The sport package comes with the akebono set up and larger rotors already and the non-sport doesn't. What exactly are you asking?

 

you mean you want to sell your OEM 14" akebonos and just install the small 12.6"/12.1" g37 non sport brakes?

yes you can but you'll have to make sure you get the OEM lines as well

 

Keep the larger brakes and just upgrade the rotors, pads, lines, and fluid.


What is the stopping distance between sport and non-sport?

 

maybe he's going aftermarket and selling his OEM's

 

wow I'm so confused...

I'm going to assume you want cross drilled, slot rotors to upgrade your tiny 14s to some bigger like 14.25? I mean they don't get that much bigger.

You would have to swap out most of the the associated parts connected to the brake rotors and knuckle. it'll set you back 3 grand per axle... I mean you can probably get away with like brake lines... but i mean you might as well spend the money on the braided lines and such.

are you tracking your car? racing brakes are very very very expensive to replace for a daily driver.


but if you actually mean you want to replace your sport S akebonos(4 piston 14") w/ the non-S sedan brakes (2 piston 12") . shouldn't have any issues w/ the fitting. you just need the knuckle, rotors and lines and then replace fluid.

selling the big brakes won't be an issue either.

 

maybe whoever sold him the car told him he had a sport but he really doesn't. so he thinks the smaller brakes are what is on the Sport model. LOL

 

I did notice i neglected to mention AWD. It is a G37xS.
I have gone back to the dealership on this a number of times and the 2009 x sport sedan does come with the smaller brakes. My only assumption on this is they do not consider a AWD a sports car.

 

I think you are asking to do the same thing I would do with a G37XS, which is replace the non-sport smaller brakes with the ones from the RWD "S." The AWD sport package is cosmetic only.

So yes, you can easily put the sport package larger brakes on the car. The wheels are the same, so we know that fits. There are third parties who sell OEM kits and/or your dealer could put together the same "kit." The dealer or someone else could install. Riverside Infiniti is known to do this...and I just got confirmation that my dealer in Ontario Canada is also willing and able to do this (with their own parts or a third party I would provide myself).

Now that I answered your question, I will add one to the thread: assuming one did this swap to the bigger brakes upon delivery of a brand new car, what do you do with the standard brake parts being pulled off the car? Will dealers give a credit? Does anyone need or want them on here just as standard replacement parts for when theirs are worn out? What would the whole lot be worth?

 

The answer is they wouldn't be worth much. More than likely the dealer would give them back and you;d be left trying to find a buyer. Good luck. Calipers rarely "wear out" and the rotors and pads are consumable items.

 

Thanks Marc. I think you summed it up perfectly.

 

yeah unfortunately 07-09 owners are fairly new. maybe in 2 years?

 

I'm sure you could sell the pads/rotors for a decent price though. The stock pads runs like $80 front and rear, and the rotors are probably a couple hundred for all four. I could easily see making $500 off selling them to people who need new pads/rotors. The calipers are a different story.

They're the same brakes off the late model 350Zs, G35 coupes, and G35 sedans so there's a bigger market.

 

only thing though the wheels on the X and the RWD '09 S model are not the same.
For the x the rears are x7.5, while the RWD has x8.5.
However, they still might fit because technically the x7.5 wheels up front clears the bigger brakes up front.
Still it's not a guarantee. You might need a spacer.
I'm going the same route, but might be getting the 19x9 Coupe S wheels.

 

Sorry to resurrect old post as I am also looking to upgrade brakes with an akebono brake kit (akebono caliper, stoptech rotors, centric pads) . I have a 2009 G37XS sedan with stock 18" wheels. Did some research and contacted various vendor. Some said its a direct replacement, and some said it requires offset. (dealership said the sport model comes with brembo which it wont fit on stock 18s, only on 19s. I thought I read we have akebono relabel as infiniti brakes on G37s)

Question to those that actually done this; For MY specific setup, is the akebono brakes a direct replacement or an offset is required? Is the offset/spacer a separate item from a brake kit? What is the disadvantage of an offset? How many man hours required if I bring this to a shop?

Finally, debating on slotted/drilled or slotted rotors. I also researched on this as well and have a basic understanding of the pros & cons of a slotted vs drilled rotors.

I dont track, just want a peace of mind knowing when I need to stop, it will stop, rain or shine and smoother braking(currently feels jerky when coming to a stop or this normal?). I also get a bonus bling with the upgrade. To those with real life experience, does slotted/drilled rotor exhibit the disadvantage of both slotted and drilled rotors or the advantage of a slotted/drilled rotor out weight the negatives? Again, I dont track, just once in a while a little spirited drive and for peace of mind.

Or dont bother, the stock brakes are good enough, just get better pads? Thanks everyone!
