It isnt going to fit or work period. It's a torque tube. There is no flexing between the motor in the front of the car and the transmission in the back. Its not a matter if the shaft can handle it, its the fact that it's not going to work period. The drive shaft lives inside the torque tube, mounts directly from the flywheel to the transmission in the back of the car. The torque tube keeps motor and trans locked together with no flex. just forget about it. it's not possible.

Hey Jordan@Weistec. What's up with the radio silence?

Can you please opine here, as I don't think anyone is going to be paying 2x as much for a Weistec driveshaft once we get the DSS or QA1 group buy going, unless you can give us a rundown of the benefits and pros/cons of the Weistec unit...

As a 100% certain near-term buyer, I was trying to help you out here man, but I guess you're not interested?

Jordan@Weistec

BLKROKT,

Weistec has almost a decade of experience, dating back to the Saleen days.

As a professional race car driver, & Weistec's developmental driver, I can say that our products are reliable and make a noticeable difference in performance.

Obviously cutting down on rotating weight is a huge advantage, when it comes to road racing, drag racing, or if it's as simple as wanting more feel for your daily driver.

Nonetheless, reliability is our strong suit. Not only will you find an increase in throttle response, you'll cut down on rotating weight.

Something else I've noticed when using our driveshaft - you really feel the rear end of the car.

So as a recap - not only do you have an amazing product, you have a multi championship race car driver who has raced everything from legend cars to Ferrari/Mercedes AMG vouching for it, but you have a reliability & a raw driving experience.

As for the other products you mentioned, I won't tell you to go with Weistec over the others. That is up to you. I will only tell you why Weistec products are worth your money, and provide insightful information along with great customer service.

BLKROKT

Thanks Jordan, your input on the driving dynamics is appreciated and sounds in line with what I've heard as the advantages. All good stuff.

However, are you saying that the Weistec unit is worth a 87.5% premium over the other competitive options in the market, because of what I would describe as.... "heritage"? Is that really it - are there no differences in these product designs or construction which would account for the discrepancy? Because "heritage" alone isn't worth $1300 to me, sorry.

Jordan@Weistec

Each product you mentioned is a carbon fiber driveshaft. That being said, each product will indeed decrease your rotating weight, etc, etc.

I am simply saying that when you buy from Weistec Engineering you are buying the best product on the market, that comes with great reliability and years of experience. In the world of high performance upgrades, or even in the racing world, 9 times out of 10 you get what you pay for.

That is exactly the reason why I will put my name on the line for Weistec, and continue to support their products/upcoming projects.

BLKROKT

Got it. DSS and QA1 also have fantastic reputations for quality.

So in the end, I guess they're all basically the same. I just ignore superlatives like "best" "strongest" "great" without supporting facts. Are you telling me that Weistec can't tell me the difference in the strength/size/construction of the carbon fiber tube, yoke, joints, etc any of the components here. Like, what makes the actual PRODUCT better than what else is out there. As a guy with cash for a CF driveshaft burning a hole in his pocket, give me some stats please. Torsional strength, materials, etc. Anything so I can make a comparison, because in the absence of FACTS, I'm just going to buy one of the other 1/2 price options.

Seriously I don't mean to crap all over this thread, and you seem like a really nice guy Jordan, but if a buyer of the product I'M SELLING came to me and asked me why they should buy my identical but 87.5% more expensive product over the competition, and I just said "because we're the best", I'd be out of a job tomorrow. That's frankly a ridiculous answer, sorry.

Ask Mike at MBH how that's going for him vs FI (although Mike certainly has made his case for better materials and welds - at least he makes it clear how he is different from the competition, and I believe him).

chrisridebike8

I'm glad I wasn't the only one that thought that. I thought "you really haven't told me anything..."

C63fora2w1

I kept waiting for Jordan to say oh well we are 30% lighter or stronger or have a lifetime warranty.. but nothing.

Kriston

So when do we setup a group buy for the DSS or QA1 drive shafts?

BLKROKT

Somebody is already working on it. A new thread will be started once the details are sorted out.

Vladds

Very nice. Is there a way to find out if anything has to be permanently removed from the center bearing mount ?

marioflex

I bought mine like 4 years ago. No need for any modification. It was a bolt on piece.

ritalin

If I end up keeping my car I'm in for a Group Buy.

Asher4799

my trans was slipping at WOT after five days of having the stage two blower, but if you are a face lift car the wet clutch set up helps. And if you are like me and drive the hell out of the car you're going to need to do the trans build.

Asher4799

count me in on that.

mr747

Same

roadtalontsi

i preach this to everyone. stage 2 on a torque converter car is good for 10-20kmi depending on previous condition, driving style etc...before slippage can be very noticeable. specially the 2-3, 3-4.

mr747

It wont take to much abuse but

kjkidd21

Whats the word on this? Debating whether to pull the trigger now or just wait for the group buy...

BLKROKT

No news. QA1 is busy on another project at the moment as far as I know. I'd wait if it's not urgent but up to you.

Mazspeed

Depending on price, I'd try it. Carbon driveshafts are a feelable difference.

Vladds

On my Subaru, I went through two carbon driveshafts at this point. The first was longer, for the 5 speed, the second shorter, when I swapped a 6 speed in.
The longer the driveshaft, the more noticeable the improvements. I and others on the Subaru forum saw an improvement in the gas mileage of 1 MPG and there is a reduction of drivetrain losses.
In case of the Mercedes, which has two rubber flanges at the OEM shaft, there should be a more direct acceleration feeling too.

kjkidd21

Has anyone tried DSS?

kjkidd21

So, I decided to take the bull by the horns and contact Driveshaft Shop to inquire about a group buy for Carbon Fiber Driveshafts. An email has been sent to the owner and I will provide details when I hear back.

kjkidd21

The group buy thread is linked below. Don't miss this opportunity!
