Not that I should be doing this anytime soon (like that's ever stopped me) but I've been looking at CF Driveshafts for my 2004 STI. Kinda wondering about difference in brands

Driveshaft Shop has a long reputation in the American car world
PST has one

I think I've seen some others floating about.

Curious if anyone has a preference and why

 

I personally have one from driveshaft shop. I like it. Build quality is superb. I haven't tried other brands so can't tell ya much more than that

 

Dss apparently makes all of PST (or that's the rumor around town)...

I have a DSS...love everything about it. Wish that was my first mod.

That being said, DSs are asshats to deal with, but that's probably because they own the market.

I'd get theirs again in a heartbeat anyways!

 

I have been meaning to get one from DSS. The only thing holding me back is I wanted a 6spd/R180 and only want to buy it once.

 

Don't know much about carbon driveshafts. How do they hold continues track use?

 

I think it was the early 2000 Audi s4 that ran carbon shafts stock... I'm not sure exactly what years... But if they ran it for every day use, I would assume they can hold up to a lot

 

I don't really have any reason to think a CF shaft wouldn't hold up.

If something breaks due to stress, it's gonna be a U-Joint and those are the same.
I guess if you really smashed it on something a CF shaft could delaminate... but at that point it seems like you'd damage steel too

 

From what I have seen and heard, they are very reliable and due to their nature, hold up to a lot of abuse.

There are a few cars now that have factory carbon shafts I believe.

The only failure I know about personally was on a friend's blown LPE powered Firebird track car. The carbon shaft on it slipped the collar where the carbon tube sits in a "cup" that is used to mount the U-joint. In this case it was on a dyno putting down over 700whp and it started making a strange screeching noise. The manufacturer changed their mounting style and replaced it. I do not remember who it was though. DSS specifically addresses this mounting union on their shafts, and I have a high level of confidence in them.

Another friend has broken several aluminum shafts with his '95 Camaro. So, anything can fail. Seems like there is some "resilience" to the carbon shaft, and along those lines, I have also heard/read several times that they all but eliminate driveline vibes and you can notice it on the first ten minutes of a drive after installing. Sounds great all around.

 

Yeah - I think I'm gonna get one eventually... considering how much money I've spent on the car in the last 12 months (and how well it's working) I'm gonna leave it alone for awhile.
