370z weight ratio? Front to rear.

phunk · 03-01-2014, 05:22 PM

if all you want is a 50/50 weight distribution, you guys are approaching this the difficult way.

Just put 150lb of ballast in the hatch.

Actually not sure what I want. I just know what I have now and I don't think its ideal.

Lol but that undoes all the work I did to remove everything.

You could rework the firewall and move the engine and tranny back a few inches.

electric motor and battery in the back!

I think stock weight distribution with full tank was like 56/44

Here are some more ideas.

Move oil cooler to rear.
Delete AC
Dry sump with oil tank in back of the car
Dry carbon hood pinned
Electric PS pump
Custom steering rack

And yes losing brake rotor weight is huge.

Might do AC. Oil cooler still needs installed.

But when talking about weight distribution the wheels, tires, rotors etc don't move, they stay planted. So rotors in that sense would be pointless. Still doing them though for overall weight.

Cordially,

Well, I say..

Seriously, you want to maximize weight transfer you need more rear wheel bias. This is why 911's while not really great handling cars from a balance standpoint are extremely fast cars at the track.

Rear wheel weight bias gives a nice advantage under braking where weight transfer is larger. The car also has brakes on all four wheels meaning that traction limitations on the front wheels are not the only force at play. The rear brakes are more useful with more rear weight and also they tend to have more rubber on RWD cars.

Rear weight bias also gives an advantage on acceleration on corner exit as it allows more weight to transfer over the rear tires. The rear end being able to grip is what will allow you to get on power earlier.

You may want to do a little more research on sprung verses unsprung weight. Your first focus should always be on unsprung weight. Those stock rotors are freaking boat anchors and losing that weight makes huge difference in performance. From your suspensions ability to hold tire to pavement to accelerating and braking. Bottom line those heavy rotors are still putting more weight on front tires along with sprung weight. Your tires must overcome that weight whether it be sprung or unsprung. By removing excess rotor and wheel weight you effectively remove weight tires must overcome in a turn. Weight is weight but unsprung weight is even more important. Our cars are nose heavy to start so getting lightweight rotors does help with getting weight off the front tire load.

just run 275-295 tire sizes all around, help control that foward weight bias

Trying to if someone buys my wheels. Either 285/35 or 295/30.
