New Rotor Recommendations
Was actually looking to order new brake pads, and i have ordered from KNS before and they sure are stand up fellas! I think i purchased from Ken before. What would you say is the difference between the 3 different HAWK pads? I want to purchase the 5.0 pads , but it shows that they only have them for the rear. Would it be fine to buy a different HAWK pad for the fronts?
For the most part, yes. Street cars driven responsibly... there's no reason at all for a BBK and fancy brake parts, other than for looks and bragging rights. Simply put, the Akebono BBK is there for marketing, not for performance.
However, you do both.
So if you were to put on your Daily Driver hat... don't you think losing 10 lbs of un-sprung, rotational mass at the front corners, and 6 lbs each in the rear, is something you would notice?

As a daily driver you will never notice a reduced un-sprung weight of only 30lbs. I have been tracking cars for a very long time and I would never be able to notice a difference of 30lbs. even at the limit on the track. However, the difference in heat dissipation would be noticeable on the track.
That's an experienced opinion, and I have no personal background to refute it. But why is it people readily declare an improvement in the car's performance when going with light-weight wheels? 10 pounds reduction in a wheel & tires... 10 pounds reduction in a 14" rotor...
On the street- impossible to tell any difference, especially with rotors. What is someone going to claim? "Yea brah I can acclerate so much faster with 10lb. lighter rotors!"
I can start to feel a difference on track with a loss of about 100lbs. If you can feel that difference on the street- you are driving like a moron.

Someone with more physics can elaborate, but a rotor is a relatively small spinning disk compared to a wheel (14" vs 26"). Therefore, the spinning effect of a lighter wheel may be more pronounced than a rotor.
On a motorcycle, 10 lb at the wheels would be very notiecable.

I dropped almost 9 lbs on each corner going to forged rims, no noticable difference in acceleration or stopping, but I am getting between 55-70 miles more per tank of gas. I bought the 2pc rotors, but haven't installed them yet, switching from the regular brake to the akebono set up, waiting until spring to do it
They are probably trying to justify spending a ton of money on really nice wheels. On the track you might notice a few tenths of a second in lap time if you are lucky, but it is difficult to be that consistent every lap to notice the difference. I remember a magazine article compared different size and weight rims/tires with lap times and the differences were very small. In racing, those small details are sweated to the last ounce because sometimes that is the difference between 1st and 2nd place.

Spoke to Ken at KNS and he suggested getting the Hawk HPS for both front and rear for $150 shipped. Gonna try to change my pads one of these days when we get another 60 degree winter day in January!
To a point. I had a 370Z too and it is a bit lighter. Fortunately with the G37S sedan they basically took all the parts from the Z like the suspension, brakes, engine, transmission, chassis, etc. so the performance between the two is pretty similar. Great news for those of us who still want some practicality like a back seat and a trunk.
