I did a search, found no results ...


Does ANYONE know the weight of the stock brake rotors? Front and rear? Does anyone have a set laying around they can weigh?

I'm trying to find out if these Rotora slotted rotors are going to be lighter than stock.

Rotora front is 18lbs and rear is 10lbs a piece.

Come on someone must have a set laying around they can weigh for me...

maybe your parts department owes you a favor...

i chucked my warped stock rotors the second i got them off, heh, pretty heavy, but my slotted were lighter judging by my arms, not much lighter, just a bit

Every little bit counts

yup, less rotational mass... too bad my 17" rims weigh in at 25.5lbs + 235/45 tire, oh well

18lbs? seems a bit much

Thats what Excelerate said (the guy running the GB). I guess he would know, for shipping purposes and stuff .. they did seem pretty heavy when I was installing them yesterday

If you were installing them why didn't you just go weigh the stock rotor?

cause we don't all have scales around and think, oh, let me weigh my stock rotor, heh, its just not what comes to mind, the first thing im thinking is "i can't wait to get these shitty stock rotors off my car"

LOL take it to the grocery store and put it in one of those produce scales. Just do it quickly so no one sees you.

OEM Front Rotors: 17.8 LBS ea.
OEM Rear Rotors: 9.8 LBS ea.

hmm they are lighter by exactly .2lbs. Were those rotors you weighed completely stock, or were they ever resurfaced? I'd assume resurfacing can shave a bit of weight off them.

I weighed the rotors on my home scale which is probably off by a little. Both the front and rear rotors have very little wear (within a few .001 of original thickness) and were never resurfaced.

hmm so I guess the rotoras are the same as stock weight. oh well, I guess better to be dead even than adding weight.

That's one of the reason I went with the Brembo BBK. The Brembo front rotors are about 7 LBS lighter. The calipers are also lighter.
