Driveshaft Shop 800HP Direct Fit Rear Axle | 2009-2017 Subaru STI (RA8530X4)2009 2017 STi Direct Fit 800HP Rear Axle Its been a long time coming for this set of axles. When the STi came out, many had surpassed the 600HP mark and we went right from the axle bar upgrades using the factory CV's to the level 5 Axle and Hub kits. Some time has passed and the cars are starting to get older, and most builds are under 800HP so we decided to make a direct bolt in axle that will support 800WHP. This is similar to our Level 5 axle
2009-2017 STi Direct Fit 800HP Rear AxleIts been a long time coming for this set of axles. When the STi came out, many had surpassed the 600HP mark and we went right from the axle bar upgrades using the factory CV's to the level 5 Axle and Hub kits. Some time has passed and the cars are starting to get older, and most builds are under 800HP so we decided to make a direct bolt in axle that will support 800WHP.
This is similar to our Level 5 axle except the outer CV is made from Billet Chromoly and the internals are also made from the same high grade material, while using the original spline size to fit the stock hubs. To make sure the center bar was up to the task of hard launches, autocross and rally demands, we have decided to use the new 300M material we have been getting directly from the mill in Sweden (*Ovar). This material has proven to be without a doubt the strongest and most resilient bar material we have used to date. Also we have recently changed the inner CV from a tripod design to a full ball and cage design with a larger radius to the spline plug for added strength.

Base part of it
Color: Black
Even though I kept this it’s very uncomfortable because of the way the base works . They are very long at the bottom and it’s hard to open and close

Great room separator
Color: Black
The panels are much longer than we expected! We only needed 3 of the 4 proivided. It's slightly flimsy, but holds together nicely. The screwdriver that came with did not fit the screws, but luckily we had a Phillips head. It's very lightweight. It is definitely a good value for the money.

Room divider
Color: Black, Color: Black
It was much simpler than anticipated. I don't think it's very sturdy and it lacks weight, but it's attractive.
