Noob Rotor Question

Paskii

Hey guys,

Been trying to determine if it's worth it to replace the stock front rotors with an aftermarket one. Main reason being is the weight reduction and hoping to save some gas if possible.

Has anyone tried replacing the stock rotors and use the stock Nissan Sport Calipers?

Thanks!

The gas you save wont be enough to pay off those fancy rotors

The aftermarket 1-piece rotors weight exactly the same.

The aftermarket 2-piece rotors are expensive, and many of the rear kits have steel hats and hence weight the same.

You are probably right but I'm thinking long term like years, at the rate gas goes up I should save something LOL. Maybe if Donald Trump becomes President and does something to lower gas price.

I'm planning to only replace the front rotors for now, CZP seem to have a promising product with a 2 piece front rotor for around $800 or so with aluminum grade hats. Saving 7lbs per rotor making a total of 14lbs, sounds decent. Anyone know how to convert this to static weight? Besides changing the rotors I want to use my stock Sport calipers, not going to track the car just a daily driver vehicle.

You are spending $800 to save 14lbs on a 3350lbs car?

Paskii

LOL 14lbs but converting it to static weight it could be a lot, don't know the math but I'm hoping that it's 100lbs or so?

you will go .05 sec down a quarter mile.....

kenchan

oh noez not this again... (not you cossie, this weight savings mumbo)

ChrisSlicks

The bonus only comes in acceleration (and handling if driving on a race track which you say you're not going to do), and will be minimal given that each wheel and tire weights 55lbs.

There is no direct conversion of unsprung weight to static weight. Yes, removing unsprung weight is always beneficial but trying to save a few pounds on a street car doesn't make much sense. I didn't notice any dramatic acceleration performance improvement when I went to 2-piece rotors and AP calipers.

I think I'll be lucky to even get that but I concur spending that much money may not be worth it hence I'm asking about this and see what peoples feed back are.

LOL it's a legitimate question though.

Thanks Chris for your input, I saw on another thread where you upgraded to the AP set up its nice! I plan to change my rims and tires with a light weight setup as well, probably going with the TE-37SL not sure about tires. Any suggestions?

cossie1600

slicks. you will go faster with just a set of slicks than shaving 50lbs from each corner with regular tires

ChrisSlicks

For a summer only tire I like the RE-11's the best. If you planning on driving in the winter then you will need dedicated winter tires as well.

Minimizing unsprung weight improves your suspension and handling dynamics. Less weight means the unsprung running gear can follow road contours and recover more quickly. But yes, changing rotors to improve gas mileage is just silly. You should wax your windshield while you're at it .

It's like those Prius guys taping their grills, removing insulation to save gas...

Paskii

Cool thanks Chris I heard a lot of positive feedback on the RE-11's will probably go for that as well.

HAHA ok I get both of your points and the consensus is that changing the rotors will barely improve acceleration and have no impact on saving gas.
