See Why the M3 M4 Carbon Fiber driveshaft is so cool (video on CFRP drive shafts)

dimabimmer · 01-09-2014, 05:04 PM

THIS?

LI2002tii · 01-09-2014, 05:31 PM

That's really cool!

kdbryce · 01-09-2014, 05:49 PM

very cool stuff

btbossman · 01-09-2014, 06:25 PM

Very Cool...Gotta love that CF!

r3dbimmer89 · 01-09-2014, 06:36 PM

Very cool, although, like previous posts have stated...this isn't something new...

PhillyNate · 01-09-2014, 06:55 PM

Great vid. I thought carbon fiber was a little hype...not anymore!

Bemo · 01-09-2014, 07:10 PM

Neat stuff but the entry price will probably be 25-30k stiffer than a well-maintained E92, that's definitely getting stiffed! And you'll get a butt ugly front end.
All else is spot on! Well, we'll see about that active sound and EPS...

Lets not forget the 1997 Audi A4 B5 had a CF drive shaft.....

Its nice that the new M cars are going to roll with CPRP
Not digging the BMW propaganda/drama stuff

I was referring to the fact that the 370Z is only 4 years old, whereas the comment I replied to was inferring that the car was 10 years old.

Nice! One of my finishing touches that I had on my 06 STI. It was a great mod and so much lighter than the stock piece. Car felt more nimble afterwards.

What propaganda? That video had nothing to do with BMW.

mPlasticDesign · 01-09-2014, 09:01 PM

Impressive. I don't think you could get as high as 4500nm with the CF if the drive shaft was operating at higher temperatures, pretty sure it would be less but still greater than the steel. Where the steel performance would remain relatively unchanged at higher temps.

Needsdecaf · 01-09-2014, 09:16 PM

Looks like what I did during college and grad school. Gotta love those hydraulic testing machines and load cells.

Good point.

They were talking about the 370Z not the 350Z.

It's a nice small upgrade, but these have been around for a long time, I don't see what all the excitement is about....
