I've been presented with a great deal on a brand new G37S BBK setup for my 08 G35. For those of you who have upgraded to this BBK, was it worth the money? Did you feel big improvements in brake performance on/off the track?

Looking for thoughts and opinions.

 

Of course there is a huge differance, they're better than the old Brembo on the 350z, and they're 14.1", also you have a wide range of options for rotors and pads, but keep in mind that you need at least 20mm spacers all around, i'd recommed Project Kics spacers, they're pretty nice.

 

You'd have to ask yourself if the increased weight of the rotors (seriously heavy) is worth the improved brake fade resistance.

I don't have the numbers but I don't think the Akebono is stopping any shorter than the oem setups?

 

^ correct.
Track is a different story though.
Temperatures are almost cut in half.

 

bbk for most people are pretty much aesthetics, but if you want to shave some weight off of it, then swap out the stock rotors with the new 2 pieces that will be coming out soon

 

Ian,
Could you really feel a difference between the S brakes and the Akebono's? Would you attribute that difference in feeling to having SS lines (if you did) versus the larger brakes?

I would think that without the ss lines, there would be no difference in feeling as the stopping distances are roughly the same. The main benefit is fade resistance imo.

 

i have plan to buy akebono i have 20" with 35 offset
still i need spacers ?

 

^^ Depends on spoke design but I don't think so.

Anyhow, brake distance can be slightly decreased with race rotors and pads. The Akebono's are better on the track due to fade resistance and better braking at high speeds as opposed to the stock S brakes. 4 pistons "should' provide better brake feel (smoother with better modulation) over the stock 1 piston. I'm getting my Akebono's in about a week so i'll let you know how it works out.

 

There's a clearance template posted by COZ in the Vendor Marketplace.

 

Few areas in improvements:

1. Long life on stock pads (currently put on more than 25,000 HARD miles)
2. Quiet
3. GREAT performance improvement
4. Minimal brake dust (less than the 07 sport brakes!)
5. Looks great

Overall, it would be more than sufficient for the daily driving duty.

As for tracking, I have experienced severe fading after just about 5 hard braking. You'd want to change the pads and brake lines if you want to track these. Of course, you'd want some better fluids as well.

 

I have a bad habit of driving fast and hit the brake pretty hard, even at street, sometime at street light i come in too fast and press my brake very hard to see how would it performe, and i tried that once with my friends G37 coupe, the Akebono BBK is amazing, the car didn't suffer any fade like it would with my stock brake, usually after i do that with my car, the brake pedal feels like a sponge, so i'd recommend those BBK, and i think in the future those BBK gonna be a standard issue on all the infiniti models.

 

^ for a couple of stops like that, if you experience fade and a spongy feel, it's not your caliper/pad/rotor at fault, but your fluid.

I've had the stock S brakes (non-Akebono) on the track, and with proper fluid that thing works pretty darned well -- and i've had it haul down to 30-40mph from 130mph multiple times on OEM pads without issue. It does start to lose it's kick eventually.

I just put on the Akebono's, also on OEM pads for daily driving. So far, it's really no different in daily driving from the non-Akebono "S" brakes. I didn't really expect initial clamping forces in daily life to be that much different.

Once this baby goes back to the track, i'll bet you i could do more laps without much change in feel primarily due to the larger rotors.

 

Thanks for all the input guys. So it looks like other than just cosmetic appeal, I would be spending extra cash and adding more weight to my car for not too big of gains as far as a braking performance. I don't track my car nor do i ever expect to.

 

i would think if you were to get that kit, 2 piece rotors would be a must.

 

I have them on my 2005 coupe with the stock 19" Rays. No spacers. The rotors went right onto the stock hub and I have about a half inch of space between the caliper and rim.
