Shaved off some weight, balanced, and milled out to 3mm. And lets just say it ended up being MUCH cheaper then racing beats set.

 

Nice they look clean

 

how did you balance them?

 

You would be surprised at how often the balancing is done wrong though.

 

im pretty sure i can trust the guy that did them
and yes ive heard horror stories about balancing gone wrong lol.

 

how much weight did you remove?

 

Looks good, was the weight removed for balancing only? Any of the lightened rotors I've seen have large areas behind the sideseal grooved milled down.

the fresh 3mm slots should serve you well

Now install them and come to DGRR

 

from what i was told .. roughly one pound if i recall correctly

 

One pound? Someone's fishing and I'm not biting. You removed 1/19 of the entire rotor?

 

like i said from what i recall. i dont know the exact weight that was taken out/off.

 

It honestly looks like from the pics that they were just balanced. The places where one would normally remove material are barely touched. But any material gone is a good thing.

 

not sure why you would lighten the rotors if you're not going to use a light flywheel

 

You mean around 1/9...

 

Each rotor is 9.5 lbs. 1 lbs was claimed to be removed from both rotors or .5 lbs from each. .5 is 1/19 of 9.5

 

That rotor has not been lighten. if you look by the side seals are there is no material taken away. Also were the roll pins are Racingbeat installs snaprings to keep the inner bearing hub from coming out. I think you got taken.
Thanks Robert

 

Misinterpretation on my part.

 

no weight taken from the side areas ... it was taken out from the inside

 

Do you have pics?

 

i have the weighed amounts and pics of in progress (didnt receieve em yet) from the guy that did the work.

 

why are you using the stock flywheel? is this going to be a drag racer on slicks?

 

Lol... lightened rotors with a stock flywheel makes no sense to me...

 

Thats the first time I've heard of that being done.. I would think removing weight from the outside areas would be much better than removing weight from the inside. All the lightened rotors I've seen have had material removed from the outside. It does look like your rotors just had some removed from the outside just for balancing..

 

has your guy done other rotors the same way?
im no expert, but it seems that if I had a rotating mass that I wanted lighter it would be less stressfull on the rotating assembly if I removed the weight from the outer edges, this way there is less rotating mass.

Just discussing thats all.

 

yeah they dont look like lightened rotors that I have seen, i am interested to see the pics of how it was done.

 

was told that removing weight from the side seal could cause those areas to collapse under high rpm runs (keep in mind this is auto/roadracing .. so lots of high revs and on/off throttle constantly)

i wanted the benefits the flywheel had for the autocross purposes.
