Went to a friends workshop to install the Mines carbon driveshaft. To my surprise I found out it was actually for a R32 GTR and had some spacers and adaptor plates to fit a R34 GTR. I had also bought a Driveshaft Shop one to compare them, The Driveshaft Shop carbon shaft was all round a better item. The weave looked better, well balanced, better finished and lighter.
I have a Japanese brand theme on the car but considering the condition and quality of both items (also that the DSS one was actually made for a R34 GTR and the Mines one is for a R32 GTR) I decided to go with the DSS item. It was also a brand new item, rated to 1200hp and has a 1 year warranty, so was a no brainer. I have yet to drive the car with the shaft installed but here are some pics comparing the two shafts and up close images of the DSS one.
I put the DSS one on the scale and it only weighed 7.5kg which is remarkable. I'll weigh the stock one on the same scale (should be 13-14kg) and will try weigh the Mines one too before it is sold.
Here is a description from the DSS website.
Product Description
This is the complete Carbon Fiber driveshaft for the R34 Skyline GT-R.This is a 3.25" High Modulus Carbon Fiber shaft that uses a CV in the rear but has had the internals changed to a higher grade chromoly and is a direct bolt on. This single shaft eliminate the factory 2 piece shaft. By removing the factory 2 piece shaft the car will lose the excessive motion caused by the hanger bearing moving up and down when you step on the gas. This will make the car react faster to throttle input and make the car feel more responsive. Rated to 1200HP with a 1-year warranty. Here are some of the other benefits of our Carbon Fiber shafts:
1. Direct-fit flange to mount up to the transmission
2. 3.250" High Modulus Carbon fiber tube with New DSS bond method. The Tube is smaller than others offered so there will be no clearance or heat issues.
3. New version 300M Spline for the CV mount that is stronger than the rest of the shaft
4. Custom modified High Speed 108mm CV with special boot and grease that is a direct fit to stock differential flange.
5. All Hardware included
6. 1 Year Warranty
7. 1200HP Rated
8. Balanced on one of the most sophisticated balancing machines in the industry.
9. Carbon shaft will be about 1-2lbs lighter than the Aluminum shafts but are much more torsional and will reduce noise in the cabin.
