If you've been following the Third and Fourth Gen F-Body Differential R&D 2012 Thread then you know that I've been working with Quaife to make a differential for 3rd and Fourth Gen F-bodies. I think we've got enough info and we've checked other manufacturers as well and it sounds like Quaife is the only game in town for a Helical Diff.

Quaife's diff will have a 3:1 bias ratio using 37 helix angle. It will be backed by Quaife's lifetime warranty which even covers race usage. The estimated cost is $1050-$1100/unit. Once 10 people express interest, I'll get the final pricing. We'll need orders for 15 units for Quaife to start production. Lead time is 8-12 weeks.

The group buy will go through me and when it comes time to pay for the units payment will be made to MLS Motor Racing (my company) via paypal. In the interest of full disclosure I want everyone to know that I'm not making a dime on this deal and I'll be paying the exact same amount as everyone else. Please keep in mind that I'll be on the hook for this deal if people back out after the order is placed therefore please be sure that you can/will follow through if you commit cause my wife will kill me if I end up with $30,000 of diffs.

Per John's suggestion, I would like to collect payment at the time we place the order.

Group Buy Members:
1. Eric (me): Committed
2. Brian (Too Z Max)
3. John Crouse
4. Mike P
5. Jason Swindle
6. Tony P.
7. Mark (Conemark)

This group buy is for stock 3rd and 4th Gen F-bodies with 7.5 rear ends. I'm not sure if Quaife makes diffs for the 12bolt and 9 inch, I haven't checked into it.

I'm not sure of the TrueTrac's bias ratio (for some reason 2:1 comes to mind, but don't quote me), but during my search I found their warranty info which states that motorsports voids their warranty. Quaife's warranty on the other hand does apply to motor sports applications.

If someone would like to call Eaton and find out the bias ratio please post it up in our "Diff R&D" Thread
