I currently have the non sport brakes, but I'm looking to upgrade to the akebono brakes full kit. Will they fit? Someone told me I'll have to order some extra parts in order to make it work.

 

Here's the kit from CZP
Akebono Infiniti Front and Rear 14 Inch Big Brake Upgrade Kit 07-08 G35 Sedan, 09+ G37 Sedan, and 08+ G37 Coupe CV36 - performance parts
Here's the Nissan kit from nismoshop (same setup w/ Nissan on the calipers and in nice gunmetal finish)
Nissan Akebono BBK Big Brake Kit Basic Upgrade - Infiniti G35 G37
And if you want to source the parts yourself here's a thread about that

You'll need wheels that clear the big calipers, a new spare tire that will clear them, and longer banjo bolts.

For the wheels, you'll need at least a 18'' set to clear the caliper. A oem sport wheel set gonna fit just fine.

 

I just put on some new Akebono pads yesterday and my slight brake squeal I used to hear every morning is now gone. Still on the original rotors though and I really cleaned the caliper pins. 66K miles on the same factory brakes and they were still good actually. OEM pads are so dusty. Also felt some wheel vibration at high speed braking (>130 mph) so needed to upgrade.
