lightweight

Are the any rotors on the market that drop a decent amount of weight?
I really don't know how to drop rotating mass besides a aluminum drive shaft, pullies and rotors.

Racing Brake rotors. They are 26 lbs lighter than OEM. Apex-Speed has the best price on them btw.

There aren't really any options for the v6 brakes. I have some R1 Concept rotors and after replacing all 4 I only saved a little over 3lbs. If money isn't an issue then I would upgrade to the brembos and then buy the Racing Brake rotors that were mentioned.

Racing Brake is the lightest option I am aware of and they perform great as well. You can save a lot of rotating mass with wheels and tires as well.

Isnt the equation supposed to be,roughly, 1 lb of rotational weight is worth 10 lbs of regular weight and shaving 100 lbs of.regular weight is worth .1 in your 1/4? Talking about shaving off a 1/4 second. Not a cheap way to get faster but hey it works

[ender2664]

26lbs I assume is 6.5 at each corner, right?

[ender2664]

I am sure it is probably posted on here somewhere, but is there a list of rim weights?

[ender2664]

Is there a calculation for how much 1lb of rotating mass shaves?
Or does it depend on speed, diameter rotating and other stuff

[tanur420]

I said .1 in your quarter time per 10 lbs of rotational weight. 26 ,lbs would be .26 which os just over a 1/4 second off your 1/4 mile time

had the racing brake rotors on my 2010 SS and they are nice. In fact I have them for sale now, see my sig. They will get you the most weight reduction of any rotors I have seen and they run cooler than others as well.

[ender2664]

You still selling those?

That is only taking into consideration straight line acceleration but reducing weight, specifically rotating mass that is also unsprung weight, improves performance across the board; acceleration, handling, and braking. Not to mention that the rotors themselves will perform better than stock and run much cooler.

5.5 off each of the front rotors and 6 of each rear.

Tru Dat! Mine should be here tomorrow! Then MSR Houston on the 3rd.
