Does anybody know were can I find one? Please post the web site, thanks.

 

I made a net search and found this shop: dennys driveshaft. They make driveshaft for any application. I will like if someone of you have experience with this people or their product? please post.

 

What's car is this driveshaft for? You know RX-7s have alluminum driveshafts right?

 

 

you have a link for that?

*edit*
nevermind

I did not know that.

 

Yo,


You want a carbon fiber driveshaft. When it breaks, it turns into a big bushy hairball, not something that's gonna come through the floorboards. But if you're running an NA 13B, that prolly won't ever happen. *grin*

oh wait, like everything mazda makes it wont fit any other cars

 

LOL

The stock driveshaft is already pretty light. Unless you've already done every other mod imaginable, your money would be better spent elswhere on the car.

 

the problem is that my mechanic told me that the U-joint are giving up. But I was wondering if a good machine shop can take the old ones out and put a new set in.
or if it will be better to buy a new one, one that i can change the u-joint when they get F$#K. Also that will be lighter and stronger.

 

today they reply that they don't have the parts to make the driveshaft for my car.

 

I believe the driveshaft is not rebuildable. Mazdatrix has a direct replacement for it that IS rebuildable.....

 

yes I have seen that driveshaft in mazdatrix. Those some one knows if it's in the same weight as the original?

 

I know you should get the driveshaft from mazdatrix if you need a new one. Then you will never have to replace it again because its not all one piece. My question is how hard is it to change by yourself?

 

It should not be to difficult because my cousin have a shop, were he tune his formula car and he has all the equipment necesary.

 

I just got a good driveline shop to remove the staked-in u-joints and put in replaceable ones.

 

from the original drive shaft?
did they replace the U-joint with some that could be replace?

 

*cough* bullshit *cough*

They'd like you to believe that...

Any good driveshaft shop should be able to remove the staked in u-joints and put new ones in. I had it done on one of mine, and they even put lube-able ones. They re-staked them in place, and used some epoxy to help hold them in.

A CF driveshaft really isn't a bad idea, for just the reason Rarest stated. It also has the added benefit of having less rotational mass, but the performance difference would hardly register on a dyno.

Not all RX's came with aluminum driveshafts. The A/T cars had steel ones, and I think some 5-speeds even came with steel shafts. I know one of my 86 GXL's did, though it seemed an isolated case. All the TII's, AFAIK, came with aluminum shafts. The funny thing is, there is almost no wieght difference between the steel and aluminum ones, because the aluminum ones are so much bigger around, almost twice the diameter of the steel ones.
