Haven't seen one on a Cobra but rather on other platforms. Obliterated it at launch.
This is some thing I will buy. If the discount is paltry I will hold off until I'm ready to install it. There are a few other items I need before this but if the discount is worth it I’m "in"
Anyone want to check with Need 4 Speed? :shrug:
Well said. That was exactly what I had wanted to say, but couldn't quite get it out, and had to settle for a "+1." :lol1:
Another question or concern I have is with it's durability. I know the "race" shaft is good to like 2,000 hp or some crazy number like that, but what about a rock or a bolt that kicks up under the car will it shatter if it gets hit? The track is generally an environment free of debris, but the street is full of little surprises. I would hate to be crusing down the highway and hit something and have my $800 driveshaft turn to dust. At least our stock aluminum one will just dent.
If you dent the stock aluminum tube chances are it's toast especially on a high powered application. A dent will cause a stress riser which is a break in the continuity where the load (torque) is being applied. I don't think debris hitting the DS is something you have to worry about too much unless your off roading. The shaft is buried up into the chassis pretty well.
The thing I would be concerned with is fatigue. Over time will the CF start to degrade making it prone the failure? The three most important things I like about this is the shock loads it will take up on the drive train, eliminating DS vibe and the safety factor should the shaft break. The problem with the shock load thing is that it suggest twisting flex in the shaft and that is where we get into that fatigue thing. Since it strong enough to handle 900 hp and I don't do drag launches I don't think this will be an issue.
Good issues to bring up though.
if they could give a ballpark price on a GP i would be in as long as the thing could last a long time of abuse.
I would buy today. I hate the vibe!!!!!!!!!
I am very interested in a group buy if the numbers look reasonable. Had anyone contacted need4speed to see if they are willing to knock them down if we can get 10/15/20 people to commit? I will be more comfortable giving everyone a 100% yes when I see how much it is going to cost me.
I would be down for a group buy!!
Very nice driveshaft!
By rev-matching you can get it to clunk a lot less if any at all.
Guess I need to drive one of the clunkier Cobras to see what all the fuss is about.
You can't go wrong with a carbon fiber shaft from PST. I'm on my second one, but the first was still perfect after more than 3 years. I sold that one for half what it cost me new, and the only reason for getting rid of it was that I needed a shorter shaft after I swapped out my OEM 5-speed for a FRPP 6-speed.
Pay attention to what you're getting, though. Just like most everything else, you get what you pay for. Last time I checked, the less expensive "street" shafts were constructed with 3-1/4" diameter tubes; the pricier "race" shafts use 3-3/4" tubes.
I'm in for a group buy if it happens. Would the group buy be for the stronger "race" DS though? Because that is the one I am interested in.
Race shaft is the only option for the 03-04 Cobras
Even better :rockon:
Just wanted to let you guys know that I've finally went ahead and organized the Group Purchase we've all been waiting for... Please see the following thread for more information.
I'm interested in getting in on this GP, but I tried clicking the link, but it won't allow me to see it. Am I the only one? :shrug:
