Himni Racing teams up with ATG to bring you a one of a kind, wooden rotor shift knob for your rotary powered RX-7 & RX-8. Another HR exclusive, extremely rare limited edition knob with only a very minimal amount produced in total. Each one is hand made in the USA using only fine exotic woods from around the world, that include Black Ebony, Black/White Tiger Ebony, ZebraWood, Honduran Rose & PurpleHeart.

The design of the knobs was carefully chosen as being the ideal shape, style & size to promote comfort & performance on the RX-7 & RX-8 shifter. Direct screw-on, each features all steel internal threads & an HR designed & detailed rotor engraved on the top. The polished finish may be left in raw form or may also be clear polyurethane coated for that extra shine. Made from woods that are 100% nontoxic & unlike metal, will not super heat in the sun or burn your skin off after baking in the heat all day. They truly provide that personal feel not otherwise possible from using metal alloys. Because they are handmade, no two are exactly alike to the T. Get yours while there are still some left as there are no plans to produce more in the future.

EXEDY Racing Flywheels are made from solid one piece billet chromoly steel forgings. They are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance air flow to improve the cooling of the clutch. The ring gear teeth are milled onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and have the possibility of separating from the flywheel.

Not for use with Exedy Hyper single, twin, triple or Carbon clutches. Works with standard steel pressure plate clutches only. (ie, stage 1, stage 2, etc) Requires counter weight solid separately.

NOTE:: This flywheel fits all of the rotary cars listed below. Exedy counterweight part numbers however are listed as fitting both the S4 & S5 TurboII. This is not correct. Only S5 & S6 share the same part number. (use the same rotors) We recommend using a ACT counter weight to insure a properly balanced rotating assembly. See below.

Exedy 12 LB Racing Flywheel Fits:
-87-88 S4 Mazda FC3S RX-7 Turbo II (use with ACT Counterweight P/N: CW01)
-89-91 S5 Mazda FC3S RX-7 Turbo II (use with ACT Counterweight P/N: CW02)
-93-95 S6 Mazda FD3S RX-7 TT (use with ACT Counterweight P/N: CW02)
-04+ Mazda FE RX-8, 6 port (use with ACT Counterweight P/N: CW03)
