Carbon Fiber Drive Shafts

[Mikes2nd]

I have the PST 1 piece CF full and the front half on my other car(ACPT from Dynamic Racing).

No vibration in any form.

BOTH make a HUGE difference on drivability. I won't own a 3s without one.

Its better all around, no more 40lbs rotating mass, your car is 20% better across the board. No more worry about driveshaft bushings... no more worry about it breaking, lower revs when pulling away from a stop light/sign. Quicker acceleration, lighter car...

Whats not to love? If you can get one used, get one. If you can afford the 1000$ i think its a great bang for your buck.

Daily driver? A must? Nothing is a must. Just you'll enjoy driving the car by 15-20%.

I can pop my clutch at like 800 rpm and it takes off.

Hey Mikes2nd, I think I tried to buy your carbon fiber shaft from you at one time many many years ago.
Well I went with a used two piece ACPT. In my opinion, getting rid of that lobro joint was the best part of having the carbon shaft.

I have had my PST 1 piece since I bought my red TT a while back. It has always vibrated and rotating it doesnt solve the issue. I also swapped it into my other stealth and the only thing that changed was the mph at which it vibrates. People say its motor mounts, but mine are in good/great condition. I even had the thing balanced again just to make sure. I now have stock drive shafts in both of my cars. Yes, the car has more off the line power with the CFDS, but once you get out of 1st you hardly notice a difference. High speed crusing is also much better with the stock shaft. If you are looking to drag race then its a good idea, but lighter wheels might be an even better option IMO.

anyone tried taking them to a shop and seeing about balancing?

Wow, are they $1400 now? I seem to recall that they were $900 on PST's original group buy way back in the day. I love mine

I've ran about 4 of them both ACPT and PST in 1-piece and 2-piece varieties. I've never had an issue with vibration as long as the rest of my drivetrain parts weren't worn. I've had motor mounts, rear diff bushings, excessive diff backlash/preload, transfercase slop especially in the tailshaft bearing, and worn splines all cause vibration. Once those things were fixed there was zero issues. The stock driveshaft and carrier bearings just mask necessary maintenance that needs to be done on every single 3S. Anyone that has vibration issues doesn't understand exactly why and blames it on the shaft itself. Having it rebalanced again should be enough to conclude something is wrong with your car.

Yeah I came across that but I wasnt sure if it was a full length 1 peice shaft or just the front section

Yea that's more what I was thinking too,that the vibration issue was more related to mileage&maintenance
