Look forward to installed shots

 

I got my car washed and the annual rip off, er, inspection done yesterday.

And the cold spell has broke, temps are back in the high 50s - low 60s, which makes summer tires so much more enjoyable

 

Well theres a ton of used drive shafts around me for $160-180ish range. So a replacement shouldnt be that bad. The install is pretty straight forward, heres a couple vids that show the process.

this one around the 7min mark

 

Is there a metal driveshaft available for FM cars?

 

Thanks man! I’ve been working on cars 10+ Years, driveshaft is an easy job. I bought a used DS off eBay for 130$. Will be taking measurements and contacting DriveShaft Shop for a custom made CF one.WOULD ANY ONE BE INTERESTED IN A GROUP BUY IF DSS WOULD BE UP TO IT FOR SEDANS? looking at their site they only list options for the coupe.

 

^ I might be interested in a CF driveshaft depending on price and lead-time.

 

Too bad you cant just take the stock CF driveshaft from a 350z and put it into our cars.

 

*370 but I wish.

 

Adrians car is a VQ35HR, so the 350Z one from a later model 350z, I wasnt wrong But yes, 370s have them as well. Unless of course the hr 350 uses a different manual transmission than the g35 does.

 

I stand corrected I thought the 370 was first to receive thanks for the info!

 

Lol, I had to go back and do a quick google search. I actually didnt know the 370 had them as well haha.

 

While that does sound nice, I'm not personally in the market for one and I would not want to be the guinea pig with it. No offense by that but if you do go through with be sure to give us some feedback

 

Probably once a year, I dip into the idea of getting a light-weight driveshaft... aluminum or CF. Each time that happens, I come away thinking "no". Or at the very least, not yet.

The aluminum shafts are more prone to damage and imbalance than OEM, and I believe CF shafts have to be custom made for the Sedan. (Because the Coupe gets the most attention for stuff like this, and the Sedan's shaft is a two-piece design.)

From what I've read, labor is relatively easy for a competent mechanic... likely 2-3 hours. Materials cost for new can be a broad range between $600 and $1200. And while together that's not a fortune, I do think its ROI is poor. In other words, the performance gains in minimizing this particular rotating mass just isn't worth what you pay for... which is purely guesswork based on light research.

Add to that the very real potential of awkward NVH going to a one-piece shaft in a car that wasn't intended... I'm just not there (yet). But still keeping an open mind, because never say never.

 

1. Lighter wheels and tires are the easiest.
2. Next easiest are two-piece rotors.
3. Next come pulleys.
4. Now think about that driveshaft.

Of the four, pulleys tend to show the least improvement but are significantly less expensive than the other three options. Lighter wheels, tires, and rotors have the added benefit of improving ride and handling.

 

I have similar concerns as you regarding increased NVH/vibrations from an aftermarket CF drive shaft. And I have yet to have any issues with my OEM drive shaft even with ~460 rwhp (knock on wood), but I simply enjoy working on my car so I'm not averse to trying something new even if I end of going back to OEM.
