86-95 Rx7 13B 2mm Solid Corner Seal Set (ARE88)
This was designed by David Atkins and has been patented.
This is an excellent upgrade to any engine. These are desirable under high boost or nitrous applications.
This is a one piece corner seal. Can be used in place of the 2 piece design with plug. Can be used with the wire type corner seal spring or the 93-95 HP wafer type spring. The 93 Style spring is recommended.
Mazda basically copied our design with the Rx8, getting rid of their faulty rubber corner seal plug and opting for a steel one basically making their corner seals solid like these.Do not use these with lapped side housings.
86-11 Rx7 & Rx8 Atkins' Thermal Pellet (ARE50)
Fits 1986-2011 Rx7 & Rx8 models, doesn't work for rx7s before 1986.
The factory thermal pellet acts like a thermostat for the oil system. When the oil is cold it does not allow full flow to the rotors for cooling, only enough for the bearings. As the oil warms up it allows more & more oil to flow. When this fails, it does so in the cold mode, thus not allowing oil to fully flow to the rotors, which overheats them and causes damage to the oil control rings. This does not increase oil pressure."For off road use only."
When the factory thermal pellet starts going out the thing clients comment on the most is excessive oil smoke at start up, which tends to go away as the car warms up and the catalytic converter cleans up the exhaust. Some people even notice the oil pressure being slightly lower.
Our replacement pellet keeps the engine oil in warm mode so that oil is always flowing to the shaft thus fixing the problem of the faulty factory thermal pellet.We don't know who started the rumor on the internet that this increases oil pressure, but it does not, for that you would need something like our increase oil pressure kit.
Fits turbo & non-turbo.
Instructions for installation of the thermal pellet.
For off road use only....Front Hub Bolt Torque Specs:
79-85 Rx7 72-87 ft/lbs (100-120Nm) 86-91 Rx7 80-98 ft/lbs (108-132Nm) 93-95 Rx7 180-200 ft/lbs (240-270Nm) 04-11 Rx8 222-250 ft/lbs (300-340Nm) 3mm Rx7 Solid Corner Seal Set (ARE89)
(12) Patented 3mm Solid Corner Seals, for use on all 12A and 13B 3mm applications.
This is an excellent upgrade to any engine. These are desirable under high boost or nitrous applications. This was designed by David Atkins and has been patented.

71-91 Rx7 Three Window Stationary Gear Bearing (4801-10-502)
Three window main bearing for more oil flow.
Competition Race Main Bearing
Fits all rotary engines from 1971-1991, also fits automatic Rx8s from 04-11.
Mazda Competition # 4801-10-502
Racing Beat # 11114
74-91 Rx7 Race Rotor Bearing (4801-11-111)
Competition Rotor Bearing has approximately .04" deeper oil grooves and provide approximately .0005" more clearance than stock bearings.
Use on any rotary engine from 1974-1991, and automatic/low power Rx8s.
Detailed images show competition and stock bearing so you can see the difference.
74-11 Rx7 & Rx8 Corner Seal Spring Set (ARE85)
(12) Mazda Corner Seal Springs, will fit any rotors from 1974-2011 Rx7 & Rx8, a nice upgrade from the earlier wire style corner seal springs.
Will fit any 2mm or 3mm applications.
N3H1-11-C24B
69-11 Rx7 & Rx8 Competition High Flow Eccentric Shaft Oil Jet (8553-11-411)
Fits all rotary engines.
One High Flow Competition Eccentric Shaft Oil Jet. If the stock eccentric shaft is being used in a high rpm engine, replace the stock oil jet check ball and spring with a Weber #200 carburetor air jet (part #77401.200).
The Weber jet is simply pressed into the back of the this oil jet. This modification is not recommended for engines that will see any street use as it will lower your oil pressure.
If using this modification you will need to increase oil pressure with a competition rear oil pressure regulator and shim your front oil pressure regulator spring.69-11 Rx7 & Rx8 Competition Eccentric Shaft Oil & Weber Jet Kit (ARE103)
Fits all rotary engines.
Two Competition Eccentric Shaft Oil Jets & Weber Jets
This modification is not recommended for engines that will see any street use as it will lower your oil pressure.
If using this modification you will need to increase oil pressure with a competition rear oil pressure regulator and shim your front oil pressure regulator spring.86-95 Rx7 13B 2mm Racing Beat Aluminum Filled Carbon Apex Seal Set (11011) - NLA
Out of stockNo Longer Available.
Racing Beat's 1986-91 13B Non-Turbo (2mm) Carbon Race Apex Seals are specifically designed to replace the stock cast iron apex seals in rotary engines operating near, or above, 8,500 RPM. These aluminum-filled carbon apex seals are a one-piece design, 2mm in thickness, and must be used only with our special Race Apex Seal Springs. We do not believe these seals are appropriate for turbocharged applications because of their fragile nature if subject to detonation.
We do not recommend the use of 3mm apex seals in the 1986-91 Non-Turbo 13B rotor. If you are experiencing apex seal failure, the probable cause is detonation.74-85 13B 3mm Racing Beat Aluminum Filled Carbon Apex Seal Set (11013) - NLA

Aluminum-filled carbon seals are a one-piece design, 3mm in thickness (13B), and must be used only with Racing Beat special Apex Seal Springs.
We do not believe these seals are appropriate for turbocharged applications because of their fragile nature if subject to detonation.

04-11 Rx8 Atkins Apex Seal Set (ARE111)
04-11 Atkins Designed Competition Renesis Rx8 Apex Seals
All of our apex seals are heat treated.
The material for these seals has been developed by David Atkins over his extensive racing career in order to exceed stock apex seal life and durability.
These are designed to take more abuse then stock apex seals, these are competition aftermarket Apex Seals.
See below for apex seal specifications.
74-85 13B 3mm Racing Beat Apex Seal Spring Set (11017) - NLA
Out of stockRacing Beat has stopped making these.
(6) Apex Seals For use with Racing Beats Aluminum Filled Carbon Apex Seals Only.
Complete set, enough for one engine.
86-91 Rx7 13B 2mm Racing Beat Apex Seal Spring Set (11015) - NLA
Out of stockRacing Beat Race Apex Seal Springs, specifically designed to fit the underside of our 1986-91 Non-Turbo (2mm) Race Apex Seals, provide proper pre-loading for these lighter one-piece seals. Unlike the stock inner and outer dual apex seal spring configuration on the 1986-91 13B engine applications, only one (1) Race Apex Seal Spring is required for each Race Apex Seal.
74-85 12A Racing Beat Apex Seal Spring Set (11016) - NLA
Out of stockRacing Beat has stopped making these.
For use with Racing Beats Aluminum Filled Carbon Apex Seals Only.
Complete set, enough for one engine.
04-11 Rx8 Atkins Solid Corner Seal Set (ARE112)
Patented 2mm Rx8 Solid Corner Seal Set
Do not use these with lapped side housings.
84-91 13B N/A Rx7 Atkins Designed Six Port Actuator Valve Kit (ARE113)
These fit a 1984-1991 13B Non Turbo Six Port Engine.
Expect about a 2hp gain.
Enough for one engine, stock actuators have a dead spot at the end of them where the intake air hits a dead spot and cavitates instead of continuing into the engine. Our intake actuators fix this problem by creating a smooth transition from intake to engine and generating more power.
Don't waste time gluing inserts into your actuators that have the possibility to fall out, just put new and better actuators in and be done with it.
71-85 12A Rx7 Front Type I Hardened Stationary Gear (10010) - NLA
Out of stockThis is No Longer Available.
Our Type I Modified 12A Front Stationary Gears are strongly recommended for engines which are regularly running near or above 8,500 RPM. These gears have had several machining modifications performed, as well as heat-treating of the teeth to improve fatigue resistance and yield strength.
Stock bearing is installed.
