I just put the rotor on a scale and it weighed in at 19 lbs., although the reading could be off by a bit as I used a bathroom scale.

I swear I didnt use much brakes to completely stop, just his body under the tire did the trick to slow the car down.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

24 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

On the 318mm C2 rotor, they are HEAVIER -- around 20lbs. Riad's 22lbs is probably about right for C4 or later C2 S 330mm (just caught that in his sig.) LOL!!!

POST 10Original post

Just had a set of front rotors delivered from performance parts. official word from the UPS guy was 'this box is damn heavy'

POST 11 / ORIGINAL POSTEROriginal post

any chance you can put one on a scale prior to installing?

I had a German Shepard stop my 3500lb '69 Camaro Convertible once. I swear I didnt use much brakes to completely stop, just his body under the tire did the trick to slow the car down. No more details....... Moral of the story: Dogs are not good brakes for cars........

POST 15Original post

I have a new pair of OEM front rotors, which I purchased from Suncoast, for my 2000 C2. I just put the rotor on a scale and it weighed in at 19 lbs., although the reading could be off by a bit as I used a bathroom scale.

POST 16Original post

I just had a set of rear rotors delivered, I'll weigh them tonight - but they are for the C4S and Turbo so they might be larger.

POST 17Original post

Quotes source post: 5209045

I'm curious to what they'll weigh! No front rotors?

POST 18Original post

Quotes source post: 5210108

I already replaced them... fortunately the front and rear wear out at different times

POST 19Original post

The rotors weighed exactly 20lbs with zero percent body fat.

POST 20Original post

My bathroom scales came in at 19lbs for the fronts - though it was flashing 0 then 19 then 0 - probably below the weight where it could get an accurate reading. So I did the old trick of me holding the rotor Vs me not holding the rotor on the scale... And I'm not going to give you the total, but the delta was 19lbs again As a comparison, 986 front rotors come in at 14lbs each

POST 22Original post

Hmm.. not bad.. considering lightweight options out there cost $2k+

POST 23 / ORIGINAL POSTEROriginal post

All, Thank you very much for taking time to get me these figures. I really appreciate it. Andy

POST 24Original post

No problem. Me weighing my rotor on the bathroom scale with my 6 year old daughter asking "what are you doing?"... "it's okay honey daddy is just weighing his car parts." Right before the wife chimes in "you're scaring us". Followed by me exclaiming "Wow, they're lighter than I thought - less unsprung weight is good!!"
