PST Carbon Fiber Drive Shaft Installed
 

Purchased from Rallysport. Great customer service!
I didn't feel like getting under the car again so I took it to Mr. Auto Clinic who, being meticulous, took under 30 minutes to swap it out and complete an oil change. It was that simple.

Measured 13.9 pounds to a T. I did not weigh the stock piece, but it is supposed to be 10.24 pounds lighter than stock according to Rallysport.

It is as the guys at Rallysport said. The car feels much peppier and it ties all my other mods together very well. The shifts are easier (less notchiness) too. I also did not feel any vibration through the RPM range.

Cool mod. Any idea how much lighter this is than an aluminum driveshaft?

Nice! I'll go ahead and be "that guy". How much!?

Nope.

Thanks. More info and pricing here:

Looks awesome by the way!

Just a kidney :lol: Thanks.

Nice Mod! ;)

1100 bucks to lose over 10 lbs rotational mass. That's bordering on reasonable (compared to 800-1400 for wheels that drop 12-24 lbs). But I still like it. Props for doing this mod. I could see this on my future to do list, but probably when I run out of other things to do.

Wow, thanks for taking the time to do the write up and taking the awesome pictures. Glad you are enjoying the shaft as well, we are loving ours!

Thanks again!

After the differential gear ratio reduction is taken into account, the effective moment of inertia decrease is pretty small compared to wheels. Of course, wheels can only be made so light, but their effective "moment radius" is still larger.

True. I have lighter than stock wheels, pulley and the CF Shaft. The combo is pretty noticeable.

That must be pretty awesome. I personally wouldn't spend that money (aluminum makes more sense in this situation imo) but CF is always badass :D

Yeah too bad you have to get under the car to see it. :)

Who makes it in aluminum?
