4.77 rear diff gears (pinion and ring)
Category: Accessories
Price: $500
Private or Vendor Listing: Private Listing
Part Fits (you may select multiples): Series I, Series II
Location (US State/Canada/Int): CA
Item Condition: Used
These gears were used in our RX-8 race car for ONE race and are in like new condition. We have since switched to even lower 5.12 gears and no longer need the 4.77 gears.
The gears alone cost close to $1000 from Mazda.
For sale for $500 shipped anywhere in the USA.
It's best to e-mail me at magnusracing@aol.com if you have questions or wish to purchase the gears. However, I will try to check this thread and my forum PMs as well.
Thanks,
John

A lot of people have sent me messages asking how much these gears increase performance. Of course this is hard to quantify. One can expect a small improvement in acceleration due to the lower gear ratio. Top gear cruising rpm will of course also go up a little bit as well.

In any case. I'll lower my price to $450 which includes shippings.

Correct me if I'm wrong but I believe that the automatic has a much higher rear end ratio. Putting in the 4.77 gears would probably be a drastic gearing change for an automatic. Sure, you would probably accelerate much faster but your cruising rpm would probably be increased so much that you probably would not want to do this on a street car. Maybe if it's a drag car or something?
