2013 Scion FR-S / Subaru BRZ Manual Transmission Carbon Fiber 1 Piece Driveshaft #TOSH86-C by The Driveshaft Shop

The 1-piece driveshaft for the 2012 Scion FR-S / Subaru BRZ / Toyota GT86 is a complete 2.75" Carbon Fiber shaft that is approximately 1/2 the weight of the factory 2-piece driveshaft. The 1-piece carbon shaft features larger, replaceable u-joints and can handle about 800WHP. We had the tubing custom wound with a high modulus fiber to ensure the strength while making it small enough to clear everything under the car. All of the factory shields, plates and covers can be used without any alteration to the car at all. The ends are made from 6061-T6 aluminum and that shaft weighs a mere 12.2lbs. Not only will the car feel more responsive but it will also make a noticeable difference on the noise level in the car.

By removing the factory 2-piece shaft and installing a single shaft, the car will feel more responsive due to the lighter weight of the shaft and also the fact that the hanger bearing is not moving up and down during acceleration. Available for most popular motor/trans combinations, if you don?t see yours listed, custom shafts are also available.

Please Note: This driveshaft is rated to 850WHP. It is for manual transmissions only. There is an automatic version available.

Part Number: TOSH86-C







Weight

The DSS driveshaft is about 1/2 the weight of the OEM driveshaft. Big savings since its rotational mass.










Note: The scale was zeroed out with the board on it.

Driveshaft Shop (DSS) Carbon Fibre Driveshaft DIY!



Hey team 86. Today we have a new bit of kit in the labs, the Driveshaft Shop (DSS) Carbon Fibre Driveshaft. The purpose of replacing your OEM driveshaft with a lighter one made from aluminium and/ or carbon fibre is to reduce rotational mass and make power transfer from the gearbox to the differential more efficient. The net result is a more responsive car.

It is a single piece unit vs our dual section unit. Since the DSS kit doesn't have that pivot point like the OEM, then it can transfer energy more efficiently.

Unlike the OEM one, this carbon fibre driveshaft doesn't have a shaft collar. Normally having a collar is good in the event that your driveshaft falls out of the gearbox and catapults your car in the air. In this case, if there is failure in this driveshaft it will simply shatter/shred into many pieces.

The U joints are replacable and DSS claims this driveshaft can handle 800whp.
The ends are made from 6061-T6 aluminum. They've been in the business for a while making driveshafts for big power cars so I'll take their word this is serious business.

Is it worth it? We installed this in the Phastek Performance shop car so I'll @Chris@Phastek fill you guys in.

The goods

This is the end of the driveshaft that mates to the differential. It is a beefy joint.



This end slots into the gearbox. There isn't a cup on this end like the OEM driveshaft but that's okay. This end is seals the gearbox so fluid and air cannot enter or escape. Inside this aluminium end is keyed so the output shaft of the gearbox can turn the driveshaft.



The driveshaft is wrapped in this material. There is a large Driveshaft shop logo and phone number on the unit itself.



Weight

The DSS driveshaft is about 1/2 the weight of the OEM driveshaft. Big savings since its rotational mass.













DIY Lets go!

Some of these are just photos of @Chris@Phastek's car.





Here is the driveshaft inserted into the rear of the gearbox. The DSS shaft will not fill that silver cup when its installed.




This is the driveshaft to differential connection. It is held together with 4 bolts.

Depending on the tools that you have you may have to put the car into gear and/or apply teh e-brake to keep the driveshaft from turning while you break loose the bolts.
