Grannas Racing Ford 8.8" Rear Conversion Kit Install - tech info on 8.8 case differences

I put together a comprehensive youtube video outlining the differences between the three most desirable Ford 8.8" IRS differential cases along with the assembly and install process of one of my Subaru BRZ / Scion FRS / Lexus IS300 Ford 8.8 Conversion kits.

The three cases I cover in the video are the 2007-2010 Explorer aluminum case, the 1989-1997 Ford Thunderbird Iron case, and the 1999-2004 Mustang Cobra case which can also be found in the 1993-1997 Lincoln Mark 8 VIII. I keep quite a bit of cores on hand, as my 8.8 kits are starting to become quite popular.

The install covers everything from setting up the load bolts, proper gear oil/fluid, installing the girdle/cage setup, bolting on the front mount, installing the Driveshaft Shop billet 8.8 stubs, and then the simple process of putting it all in the car once it is assembled.

These 8.8 kits are available for the BRZ - FRS, the Lexus IS300 - IS200 -Altezza, as well as the MKIV Toyota Supra / Lexus SC300. The install process is the same other than the Supra uses a more simple "straight bar" front mount assembly.

So without further talk, here is the youtube video. ALSO! Don't forget to subscribe to my channel

I will be doing more and more of these "tech" style videos in the future. Next on my "tech video" agenda is a comparison between LS/Fbody T56's, the TR6060, and the T56 Magnum. It will be a good one, so please subscribe for updates! I also will be posting video of the new car and racing videos this coming season.
