Note: I'm not selling these or making any money off of this.

I've been talking to the guys at MFactory http://teammfactory.com/ who make limited slip diffs and gearsets for primarily Honda, but also other makes as well. Their parts are very widely respected throughout the Honda/import community.

Last year I put a helical LSD from them in my Civic Del Sol Si, and was absolutely blown away by how cheap and high quality the parts were. I think I ended up paying $700 for the limited slip shipped to my door.

If we could get together 10-20 orders for these things they'd be willing to make a helical LSD or a clutch-type LSD for a bit more. These would fit 914 transmissions, as well as 912 ( not 912E ) and 1964 -1971 911.

Would anyone be interested in a cheap high-quality forged chromoly diff for 901/914? If so would you want a torque-biasing diff, or clutch/plate-type LSD?
