Suberdave’s Custom Races
The missing link to the R180 install with R160 hubs…
You want to upgrade to an STI R180 rear differential – but you have a Legacy, Baja, Impreza, or Forester.
Or even more hopeless, you think, because you have an EA-81 or EA-82.
With my custom Hybrid Races – you can upgrade any of those, and keep you cost down by keeping your stock hubs!
When changing out your rear diff, you have a few options:
- Upgrade your rear hubs to use R180 hubs and Brembo brakes. Cost: $1000 – $1500
- Find a set of Spec-B axles and swap your WRX outer joints. Cost: $600 – $800
- Custom axles. Cost: $800 or more
- Use the Suberdave Hybrid Race Kit. Cost: $200 – $230
Cost:
- $200 shipped anywhere in the US
- $230 shipped anywhere else in the world (Ships via USPS)
Here is what you will get:
- 2 Hybrid Races
- 2 bags of CV grease
- 2 small CV boot clamps
- 2 large CV boot clamps
I currently offer 4 race variations:
- 05 and newer STI inner joint (8 ball cup) with 22 spline axle
- 05 and newer STI inner joint (8 ball cup) with 28 spline axle
- 04 and older STI inner joint (6 ball cup) with 21 spline axle*
- 04 and older STI inner joint (6 ball cup) with 22 spline axle
* The 21 spline axles have proved to be weaker than the 22 spline axles. If you have 21 spline axles, and are running more than 280-300 WHP, I would look into finding 22 or 28 spline axles.
These races are no longer available
- 05 and newer STI inner joint (8 ball cup) with 21 spline axle*
- 04 and older STI inner joint (6 ball cup) with 28 spline axle
Before ordering
R160 shaft: Count your splines (inside the inner joint: 21, 22, or 28).
R180 shaft: Count bearings on your inner joint (either 6 or 8).
**Make sure you check both rear axles. I have had multiple customers with two different axles.**

Notes:
For those wanting to adapt SVX inner axle joints (for use in early JDM LSD) to OEM R160 shafts – this kit will work for you too.
These races have been used in many cars from street use, to rally and drag use. I have sold many kits and have received awesome reviews.
