I'm looking into a 1-piece unit as a possible modification for my daily-driven, soon-to-be occasional track-day ride. I've searched a few past threads... Other than the benefit of weight reduction/less rotational mass, what are the positives(and negatives) in doing such an upgrade? Dynotech... Shaftmasters... Driveshaft Shop... etc.?

I'm considering to do this application at the same time I'll have the long-tube headers installed this upcoming Spring. Thanks.

 

I know a couple of Ford engineers who swear by the dynotech shaft.

Really, there aren't any negatives other than cost.

 

Dynotech would be my choice. As said above, cost is a negative. Also, you'll have to adjust your pinion angle. I see you have an adjustable upper control arm so that's a positive.

 

Thanks for the insight. I'll be giving Dynotech Engineering a call tomorrow.

 

I don't have one but I know DSS has a CV joint which is supposed to be superior to the slip yoke. You may want to check it out.

 

There is a reason that this car comes with a two piece shaft and I doubt that it's cheaper to produce. My guess is that it isolates vibration...or it's a safety thing...but I don't know for sure.

So...I would disagree that the only downside is cost. There must be something else.

That said, it's at the top of my eventual mod list. Weight reduction, especially rotating weight, is extremely important...as you know.

 

Cost isn't the only negative but it's one of the biggest.

 

it pays for itself! Thats a positive

 

I posted this on another thread. Ford engineer discusses 2 pc drive shaft vs 1pc:

I actually came across that thread... interesting read... thanks to all. On that note, the research continues. I'm hoping I can keep NVH to an extremely bare minimum with this type of application. Safety is paramount.

 

If you want safety too... go with carbon fiber it's better in every way inclulding NVH but cost $1200 plus...

 

Okay, then. I've been taking a hard look at DSS. I took into consideration what you had mentioned about the CV joint... carbon fiber sounds very tempting, but price is up there! I'll be giving them a call today for some recommendations.
