MFactory CF Drive Shaft

[serranot]

So to the testers and owners of the product, please let me know your impressions. I’m ready to pay but am more unsure of this than I was for the Karbonius or the BE bearings. Would love anything good or bad you have to say.

You're asking if you should do the driveshaft or Rod Bearings. You should clearly do the Bearings. This isn't even a question. Their still hasn't been anyone on this thread that can say it provides any real performance gains.

All everyone say is that it feels better. Your engine failing or driveshaft.

Sorry. To be clear I did the bearings over 2 years ago and bought the Karbonius. What I’m saying is that early adopting for those was an easier decision.

If you have some money to blow on a mod that will make the transmission feel a little more directly connected the differential, go for it. To me it was nothing dramatic but I also have no regrets. Don’t expect a power gain you can feel, but it’s possible a slight reduction in drivetrain loss could be measured on a dyno.

Hey Slicer, In this second photo, where did you get the square inserts/spacers to center the bolts for the Rear Toe Arms?

I've been looking for something like these, my Dinans didn't come with anything like this.. I have a make-shift washer setup currently but really like how yours is..

sorry to thread jack.

sorry to thread jack.

It's a Fall-Line Motorsports camber shim kit which eliminates the factory eccentric bolt.

[C-los]

Sorry for not being clearer, I mean the one above that, for the Adjustable Toe Arms.
not the Shim kit for the Lower Control Arm. It's Gold.

Unless I"m an idiot and can't see that it's the same thing?

[Richbot]

I think it's the same thing? rectangles lock it in place as opposed to allowing the cam on the eccentric to rotate like the stock ones. Less slippage, and adjustment is now accomplished with the threaded arms instead of the eccentrics?

[C-los]

I get the reason, i'm wondering where he got them, unless they are the same as the Camber Shim Kit.

I'm pretty sure us owners have been raving about this product throughout this thread. I said on the previous page that "[i]t's one of those rare mods that's better than OEM with no drawbacks." The caveat is that there original and current versions of this shaft. I have the original. Hopefully the current version is as good as or better than the original. Oh, cool, I'm in Moco with the exact same car as you.

Sorry, yes, you are right the shims are for the LCA. The parts to lock out the toe arms were also from Fall Line and they come with their toe arms. I personally prefer the SPL arms as long as you swap out their ti hardware for stainless. SPL sells their lockout kit separately and fall-line includes it with their toe arms. I originally had FL toe arms and now switched to SPL - as seen in the pic.

I already gave my review earlier and continue to be happy with it. Honestly more of an impact than the Karbonius airbox for me. I did not detect much, if any, auditory "improvement" from the Karbonius. However, my car has much of the sound deadening removed, rear seats deleted (with GTS cage and seat delete), plus an Akra GT4 exhaust which has no cats or resonators. My statement regarding sound proved to be controversial in the Karbonius thread but that's my assessment. My primary motivation for Karbonius was the weight savings. Somewhat the same motivation with the DS. I have developed a bit of a weight OCD with the car. I was pleasantly surprised to experience a noticeable improvement in the feel with the CF DS. I would choose the DS over Karbonius.

I love my Mfactory CF drive shaft. the car a actually feels like it has torque. Its super rev happy and you can feel the deceleration quite a bit.

slicer, is your car DCT or 6MT? Wondering if the DS is as noticeable & still worth it for DCT cars.

DCT.

Yes and yes.

[roastbeef]

this is becoming one of those mods where there are tons of skeptics that don't have it. i think it is due to thinking losing 12lbs is insignificant... its more than the weight alone. its weight in one of the most important areas to lose weight. in addition to that, it adds great feel by being one piece, which in and of itself, reduces loss.

if you go from an oem driveshaft to this driveshaft, you will feel it. it is not subjective if you will feel it or not.

[amrazM]

I just Installed this in my car, along with subframe/diff bushings and other upgrades. The difference the driveshaft makes is significant it makes the car feel incredibly direct especially in the higher rev range. The stock driveshaft feels subdued compared to this.

[Redd]

Feels more direct, accelerates quicker, DCT shifts give more of a shove in the ass, and saves me 9% gas. What's not to love?

[pbonsalb]

It does not save 9% in gas or add any power. While rotational mass is the best kind to reduce, the small diameter of a DS makes the effect less than that of similar weight savings from a lighter flywheel or brakes or wheels that have a larger diameter. It definitely does feel more direct, because it is one piece rather than two piece. Good mod, but I would not put it at the top of the list in terms of performance enhancers.

[Not Sure]

what is a fair price to get this installed? dct if it matters.
