I would like track proof that this will shave tenths of 1/4 mile times and it's not available on their web site yet

Spring is approaching, tracks will be available and I'll submit slips. The test model is sold, if anyone is interested then you will need to contact dss directly if it is not posted to their site. The final design works flawlessly, no contact with the shifter at all (especially with hard rh turns). I'll post more testing related info as I recieve it. Thanks again to those involved and I hope others will take part in probably one of the greatest aftermarket parts for our chassis.

So someone bought the test model and it is now on ebay for a practically "new" price, just FYI this was purchased by the other person from driveshaftshop for 1/2 off (original price $1450) being the test model. Spread the word on it, it wasn't defective or anything it's just this guy tryin to rip someone off in my perspective. Also, how he has it pictured is not how it gets installed, either see the first posts with pics or contact myself or driveshaftshop if you need info.

Why don't you ask Frank if he'll swap the ISF cfds for an is350 cfds less shipping and maybe a small fee?

Sorry for reviving a two year old thread but has anyone else went with a carbon fiber driveshaft also? I am genuinely curious whether or not it's worth it.

There are three general styles of drive (propeller) shafts. Steel, aluminum and and carbon fiber. There are some advantages to all three.

1. Steel of various grades is probably the best and most practical. I think steel is ideal for the F and the ones that come stock are well engineered. Not sure how we could make it better, maybe use a lighter type of carbon steel. The rubber biscuits at the ends should be replaced at some point. They serve as shock absorbers.
2. Aluminum is also quite good and usually lighter than steel. Maybe not as strong as steel but will work well and may save weight.
3. Carbon fiber will work very well and will save weight. DO NOT drop, scratch or damage this drive shaft in any way or it may break. Besides saving weight the carbon shaft will twist a bit when the car is launched (thats why they make airplane wings out of the stuff). This absorbs shock, thus the stock biscuits are not needed. These shafts work well on a stick shift car that is launched at 10,000 RPM using a hard hitting clutch.

Are they faster? Cannot imagine why they would be. Pretty hard to beat what came with the car.

The reason I inquired is I remember seeing on a mustang forum where someone replaced their driveshaft with a cf one and his dyno showed a gain of +13 whp. I know it doesn't actually make the car faster; it just helps it put the power down. I don't remember if he specified whether or not his car was manual

It's light weight so easier for the transmission to spin it I guess.

You're removing parasitic drivetrain loss. The difference between engine hp and wheel horsepower. Same goes for rotational mass on the engine assembly, flywheel if manual, wheels, etc.

Yep that's what I was getting at. Didn't know how to word it correctly. That's people some people make more who with lighter wheels and brakes.
