We can not offer this 4.777:1 Ratio Ring and Pinion Gear Set made by Fujita Engineering in Japan.
A popular upgrade for RX-7 and RX-8 Track Cars as it will increase vehicle acceleration, however it is worth noting that you will loose a little top speed in each gear.

Like the Mazda 4.777 gear set only at a more affordable price. This gear set will fit both RX-8 and RX-7 FD3s differentials.

This FEED gear set is a special order item only, and cannot be cancelled. furthermore due to the fragile nature of final drive sets we are unable to accept returns or exchanges due to risk of damage if handles improperly.

The Mazda 4.777 ratio ring and pinion set is suitable use on the following rotary applications: 1993-1995 Twin Turbo RX-7 and 2003-2008 RX-8,
This ring and pinion set will increase your vehicles acceleration rate, at the cost of a decrease in top speed in each gear.

Alternate axle ratios are available for special applications. These ratios interchange exactly with the stock parts and should be adjusted to stock specifications (except as noted on the information sheet supplied with the gear set). If you replace your existing gear set with a lower ratio (higher number) gear set you will increase the vehicle’s acceleration and move through the transmission gears quicker, but you will simultaneously reduce the top speed of the vehicle for a given rpm limit. However, if you reduce your existing gear set with a higher ratio (lower number) gear set you will decrease the vehicle’s acceleration and move slower through the gears, but the top speed of the vehicle will increase for the same given rpm limit as in the previous example.

Special Order only, once you have placed your order for this part it cannot be cancelled. This part is non returnable.

The Mazda 4.44 ratio ring and pinion set is suitable use on the following rotary applications: 1993-1995 Twin Turbo RX-7, on some model FD’s the factory fit final drive is the 4.3:1 ratio acceleration can be increased by swapping to the slight;y shorter 4.44:1 Gear Set.
This ring and pinion set will increase your vehicles acceleration rate, trading a slight decrease in top speed in each gear.

A great modification if your not too bothered about trading a little acceleration for lower cruising RPM leading to a little better fuel economy.
