Add an extra 1 litre of oil to your FD’s differentials capacity.
Increasing the capacity of your differential is something that is quite often overlooked on a performance car. Though the stock Diff holds around 1.4 litres of oil incresing its capacity can aid cooling of everything back there and prolong the life of your expensive aftermarket Diff if fitted.

A great upgrade for those looking to take their car on track. GReddy have taken this in to account by adding internal oil baffles in to the casting to reduce oil slosh under hard cornering.

GReddy have also included two 3/8pt (not 3/8npt) ports in the the casing design to allow for easy installation of a differential oil cooler (if your going that extreme) or an oil temperature sensor (yes they have literally thought of everything when designing this diff cover)

Made from cast aluminium, this cover increases the diffs oil capacity by around 1 Liter, and comes with a high power magnetic drain bolt to help keep all that new oil clean and free from debris.

This Diff cover is compatible with all model years of the Rx-7 FD

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.

Exclusive to Essex Rotary in the UK.

Offering the lightest streetable flywheel on the market worldwide, BHR lead the way in product innovation.

When it comes to your powertrain the flywheel can be a limiting factor due to it’s mass.  While at slightly less than 17 lbs. the RX-8 has a lighter flywheel than most production vehicles, Black Halo Racing has gone further to develop a much lighter alternative.  Our 9 lb. aluminum flywheel removes rotating mass in critical areas allowing more power to be translated to the wheels (which is where you want it, isn’t it!).  Our flywheel also has a replaceable friction face allowing you to reuse/repair the flywheel (if necessary) instead of having to buy a replacement should the need arise.

Necessary counterweight is sold separately.

Optional discount if purchased with a counterweight, take a look at our special offers section for model options, Package price would be £525.00 collected or £545 Delivered

From street to road racing, the Racing Beat Aluminum Flywheel is ideally suited for a wide range of performance applications.

This lightweight aluminum unit reduces the flywheel weight about 29 percent from the original, and reduces the flywheel inertia approximately 55 percent. <p>The weight of the stock flywheel is 16.8 lbs compared to 8 lbs for the Racing Beat Aluminum flywheel. For additional security, the ring gear is bolted firmly in place to the flywheel assembly.

By using this flywheel on a 5 speed RX-8 it will let you replace the small 5 speed clutch with the larger diamiter 6 speed clutch that is more durable.

The RE-Amemiya D1-Spec Short Shifter will fit both the Mazda RX-7-FD3S and Mazda RX-8 equipped with 5 speed Transmission. The shifter is a plug and play application that effectively reduces the stroke by 5mm between gears while also ‘solidly’ engaging the gears, this may not sound like a lot but it makes a big difference.

Shifting will be smoother with the upgraded brass collar compared to the OEM plastic collar and many owners report that they no longer miss gear changes during spirited driving.

This is the same part as used on the RE-Amemiya RX-7 D1GP cars.

Do note these are to fit the 5MT only and will not fit 6 speed MT equipped RX-8.
