Alright so ive been researching BBKs, mainly Akebono, and i've read that if i were to buy the Akebono 370z set up it would add a good 20+lbs.

I'm guessing thats what this one is, "14" 370Z Sport Brake Rotors"

But what about this one, its got stoptech rotors instead of stock ones. So i'm guessing this would be the better route.

Any thoughts/opinions would be great

 

any 1 piece rotor is going to weigh within a 1lb or so of any other. Only a 2 piece rotor will be lighter (by 6-7 lbs vs the 1 piece counterpart)

 

This is true.
The Akebono kit is HEAVY.
Another reason why some people like the Brembo's more.

 

I've had and compared a couple BBK's. I had a full set of Akebono's and wasn't happy with them, the kit was complete w/little issues that were addressed. They're a little wider than the OEM Brembo's so finding wheels that clear are more of a PITA. The Stoptech set up was HEAVY... and you could probably get a better Wilwood, OEM Brembo, or a Stoptech.

 

Thanks for the input all!

I do have another question, I know that people have felt the weight difference when adding the akebonos, so my question is, if i had other weight reduction mods such as, lightweight pulley system (5lbs lighter the stock), lightweight clutch set up(15lbs or more in weight reduction), etc. would the weight from the akebonos cancel out, or since the weight is right at the wheels would i still be able to feel it?

 

Nope...

 

mass, whether adding or subtracting, has different effects depending on where it is being added or taken away from

 

I'd much rather have extra weight just about anywhere besides the brakes/hubs/wheels. Unsprung weight (anything not held up by the springs) is your enemy when trying to get a nimble car.

I've had some pretty quick street cars and never needed anything beyond upgraded pads and rotors with better fluid. I did do stainless lines on one of my old cars, because one of the stock rubber lines was leaking. My point is, unless you're tracking the car then I wouldn't worry about a BBK. Even then, you probably don't need the BBK.

 

I'd imagine the difference in moment of inertia between the stock rotor and akebono rotor wouldn't be that big of a deal but i guess I could be wrong if people are claiming they "can feel a difference"

 

I was at one point looking at the akebono, but 14" wilwood 2pc rotor bbk isnt much more and you get a 6&4 piston setup.

 

i have always wanted a bbk and they look great, but they are pricey. you would be surprised by what a good set of pads, rotors, and ss lines can do...for about 600 or less with the stoptech stage II kit (not sure if fluid is included in this kit). its a nice upgrade from stock and not that expensive. anyways, good luck with your decision.

 

I have Akebonos with DBA 2 piece front rotors and don't feel any handling difference. The brakes feel great and I like them very much.

 

racing brake for akebono makes 2 piece rotors front and rear, I have a set they look very nice. But nothing to compare it to I am still building

 

ive pretty much come to the conclusion that im just gonna get some better stock rotors and pads for now. and put my money towards the tt kit im saving up for. as a bbk would mainly be for looks since i dont race or show my car. i may also track the z *someday* and when that day comes ill look again at getting a bbk. i also realized i would want two piece rotors all around and for that i might as well just buy a wilwood or rotora or another 6/4pot

thanks for all your replies everyone.

 

I strongly suggest you stay away from Rotora... and do you really need a 6/4pot set up? Wilwood and Stoptech's are a solid choice. Going FI is going to be expensive so save up and have extra "oh ****" money but it's fun nonetheless.

Just lurk in the classifieds and something good will pop up.

 

Well said.

I wish there was a simple formula where you added rotor diameter, weight, number of pots to arrive at clamping power. But there isn't one. You would have to be a mechanical engineer to make sense of all the variables.

 

Big brakes to forced induction? Quite a leap here.

 

Yup that's my plan. It'll be at least a year before i actually put the tt kit on the car. and probably at least 6months to save money until i buy a kit.

Other then to just be able to say i have a 6/4pot no. Which is the main reason im only replacing the rotors/pads right now. and will continue to think about a brake kit..

And once again davidv, thanks for your nonconstructive feedback. we can always count on it, cant we?

 

youre going TT? is the weight of the akebono bbk really gonna make you feel a difference when youre pushing over 4xx-5xxwhp? Just curious because I plan on getting the akebono kit, and later on boosting my z.

 

no, but if your gonna go faster your going to certainly want to be able to stop faster.

spending money on mods never ends btw...next thing you will want is a body kit, wheels and tires, suspension, and the list goes on.

save your money...then get a gtr
