FBM 8.8 IRS Rear Diff Conversion - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

FullBlown · 03-19-2013, 04:56 PM

We designed a conversion kit to put a ford 8.8 IRS into the FRS/BRZ. This is the same setup we used in many fast S2000's around the world.

We chose this option again, because there are tons of gear rations to Pick from.

Our kit will come complete with Driveshaft shop axles, drive shaft, studs, hubs, the whole works.

Pricing TBA

how much heavier it it? i know it probably doesnt matter since most people buying this are pushing like 55psi with one gazillion horsepower, but just wondering

FullBlown · 03-19-2013, 05:01 PM

I'll get the final weight difference, a little extra weight on the rear tires is a good thing

Pure Automotive · 03-19-2013, 05:02 PM

Can't wait to test it!

Tansey86 · 03-19-2013, 05:18 PM

Holy shit you guys do everything.

SmsAlSuwaidi · 03-19-2013, 05:30 PM

WOW full-blown are dominating !

i also assume you're another step closer to running that frs into 9's

You guys are really making it hard for me to save any money for a house lol. Props to you guys for releasing so many top quality parts so fast for these cars.

naikaidriver · 03-19-2013, 05:47 PM

Seriously! Are you guys building a Pro Street FR-S?

Between your dyno numbers and this rear-end integration, I'm starting to think you are building with a purpose in mind! Sub-10 second FR-S maybe?

You missed a bolt...

FullBlown · 03-19-2013, 06:33 PM

LOL, yes it was just for mock up.

Calum · 03-19-2013, 06:36 PM

Does this mean you've found a need for this part? Yes, I'm asking if you blew up the stocker.

No, but the stubs going into the diff will only allow for a certain diameter axle. Also the ring and pinion is pretty small.

However, we did find tons of shavings every time we tore the cover off the OEM diff. The stock unit probably would of lasted, but we did not want to invest a ton of money in to the axles, drive shaft ect.. just to find out if it will break.

The main advantage to this swap is the gear ratio options . All of which are under $200 a set.

3.08:1
3.27:1
3.55:1
3.73:1
3.90:1
4.10:1
4.30:1
