Here are a pair of Mazda OEM Engine rotors from a 2007 RX8. these are high compression engine rotors with a 10:1 compression ratio. They have been machined over to use 3mm apex seals and have also been machine and lightened and matched balanced to within 7 grams. front rotor weighs 4038 grams and rear rotor weighs 4032 grams. The bearings are in excellent condition and ideally broken in for competition purposes.

come with the broken/stuck sideseals? or whatever that is

i dont really see any lightening...

rob20rx7

There is no broken seal or any of the sort. that pic was taken before the milling of the apex seal groove was completed and that corner was heated and grided to correct damage cause by the previous 2mm apex seal. I assure you that there is no damagae whatsoever. as for the lightening. there is .100 of material removed from each rotor face. Making them significantly lighter than stock as well as matched balanced.

I understand i dont have much of a trade refference on this forum but thats because I deal more on the Rx7 forum. you can check my trade refference there and history. I do not sell crap or garbage. the only reason im not using these rotors anymore is because we have changed the set up to be run on the 4 Rotor 26B we are building to 4xS5 rotors instead.

Rob, I checked each and every page of both threads, and went had to check out Al's 7 too, congrats on your wins at Homestead, do you ever take the cars to Seabring?? I will have to ask a buddy of my at work who races a Mustang at homestead and he works on several Cobra's that race there too.

Bump and good luck on the sale

i guess you took different pics. the broken side seal pic is not there anymore. not crapping just making sure you know what you are doing and not trying to rip anyone off. we are a tight family over here :P

Do you use bigger side seals for the smaller rotor face?

rob20rx7

we havent been to homestead with the orange car yet. Our car is still in the shake down process and dont quite have the means yet of making the trip to sebring for a big event. but do plan on at taking the car to Sebring by the end of this year. Maybe for a Chin Event.

I feel you and respect your looking out. this is why i didnt take it personal in any way. Im sure there alot of people trying to scam out there these days with whatever they can. I did change the picture though after you pointed it out. didnt really mean to show that old pic and give people the wrong idea. as for the side seals, we use the same bevel RX8 side seals and corner seals. we just change the apex seal over to a 3mm seal. not that its really needed for an NA application but since we run lots of enduros during the year. Im just partial to using the bigger apex seal.

Have they been heat cycled enough to verify they won't / didn't crack / fail?

Very Interested if these rotors are proven....

Also do you have the e-shaft that was in use with these?

rob20rx7

here is a short video of the same exact set-up in another motor of mine.

http://www.youtube.com/watch?v=M_QnlHgbrPY

I only remove .100 of material so this leaves plenty of steel left to prevent cracking. I do not have an e-shaft for the rotors. I use the one in my engine now. As for heat cycle, they have only been used the amount of time they were in the original engine which was 27468 miles. Like i saud before in my previous post. I do not sell garbage. if you do the math you are getting a very very good deal. They charge about 180.00 to lighten the rotors then about 320.00 to do the 3mm apex cut plus the cost of the rotors.

Awsome deal!
i just wanna free up space and get some cash back

man i stayed up to date on your FD track car project, must say it gave me motivation! lol
Good luck with sale.

rob20rx7

Thanks for the props! if you check back there is another car we are building now which will be the sister car to mine but with quite a few more advancements. its under BigAls thread. also there is a thread about my 4 Rotor 26B build.

Really? might check it out. I did keep up with that european 4 rotor build, car was pretty tight.

wow. wow. wow.

i just checked what these weigh in pounds, 8.90 and 8.88 respectively.

thats nuts! the stock rotors weigh 9.2lbs. thats a good .3lbs lighter. that's really going to help with horsepower. i almost wish i had a reason to get my engine rebuilt right now.

rob20rx7

That is the whole idea, i use these for road racing so they are really put thru thier paces. as i mentioned before this is exact replica of the set-up in my car now and we have made 280 RWHP on a 13Bpp Engine with these rotors

kersh4w

well the renny is not a pp, but these are definitely unique rotors and will definitely help out horsepower wise.

this is the most lightened rotors i've ever seen. talk about reducing rotating mass where it really counts.

I am interested in the set. If you still happen to have them in storage somewhere. Let me know.

Bit optimistic given that it's been 12years and the OP hasn't been on the site for over 10....
