i found some one with a Center Force stage 2 clutch from their rx8 that they totaled i dont know the shape of it, but it looked fine in the pictures. anyways, he only wants 300$ for it! good buy or bad buy? i just have the original clutch on mine, and i can tell its going out. If I am going over 7,000 RPM in first gear and shift to 2nd, it just grinds and makes this horrible noise, so I have to double clutch if I want to go fast. It doesnt do that for daily driving (under 6000 RPM) It does that also randomly when i go into 5th, but not often, and its only those 2 gears....so Im just guessing its my clutch, if you have any other ideas, please tell. Also please let me know if this is a good buy!!! i dont know anything about clutches!!!

 

If you have to double clutch to keep from grinding your syncros are in bad shape, not the clutch.

 

i dont care if i sound like an idiot...but what is a syncro?

 

its not the clutch. it's the syncros....look up manual transmission on howstuffworks.com

ok so how do i fix this? from what i read ive come to understand the synchros are in the transmission, and that every gear has its own synchro, right? so if i buy a new clutch it wouldnt solve my problem. ive only had my rx8 for about 3 months, and its my first standard vehicle, so i dont know a whole lot about parts. ive never had a similar problem with my automatic cars. so would i need to buy a new transmission? i have warranty still, or can i just buy the synchros and have them replaced? thx for any more answers an info and not making fun of me

 

the only way to fix the synchros will be to get the transmission rebuilt ($$$). At this point you are living on borrowed time. the problem will get worse and that could make the rebuild more expensive, so you should get it looked at. A new clutch will not fix it. I don't know what a trans rebuild will cost, but it will be at least 3X the clutch you are looking at. Sorry for the bad news. Maybe someone can chime in with a better estimate of the trans rebuild. Also, this thread is in the wrong section.

 

What kind of fluid do you have in your current trans? I've heard of people getting rid of their synchro grinding by switching to Pure Power and/or Redline products.

I run Redline MT-90 in my trans and after 74K miles and two seasons of autocross (2 drivers 1st season, 3 drivers in the 2nd season), I've had zero tranny issues.

 

ya i was actually thinking about that. i got the car bout 3 months ago so i havnent changed or added the fluid on the transmission...so its probably some cheap piece of crap fluid. somesomeone suggested putting some royal purple in the transmission, u suggest Redline mt-90 though? Do they sell that at all autozones, or common auto stores?

 

well i have a warranty on the transmission i believe, i bought it from a dealership, it wasnt Mazda, but they gave me a 1 year warranty from an outside company for and type of engine issues. So i guess i should maybe bring it to Mazda or someone else who knows how to work on it, and go from there? like i said its not a HUGE problem...i just cant go rly fast or race when i feel like it i havnt been able to feel the true power of the rx8 yet!!! but 1st ill get some better fluid for the transmission
and ya im rly new at this cite and trying to get used to the threads and searching and stuff
