Lightweight Steel Flywheel 89-95 TII & FD

The weight of the stock flywheel is 22 lbs (89-91) and 19 lbs (93-95), compared to 17 lbs for the Racing Beat Flywheel. The actual reduction in inertia from stock is much greater than the weights suggest, since the stock flywheel is 1 to 2 inches thick at its outside edge.

Lightweight Aluminum Flywheel 87-95 Turbo

The Aluminum Flywheel has a tuft-rided steel friction surface for long life. Intended primarily for road racing and rallying, this kit reduces the flywheel weight up to 55 percent of the original, and reduces the flywheel inertia up to 80 percent of the original. The ring gear is bolted in place for security. The kit includes the rear balance weight and all the hardware necessary for installation, including special bolts which attach the pressure plate without modification.

The weight of the stock flywheel is 22 lbs (89-91) and 19 lbs (93-95) compared to 12 lbs for the Racing Beat flywheel.

Lightweight Steel Flywheel 86-88 Non-Turbo

The weight of the stock flywheel is 24 lbs compared to 17 lbs for the Racing Beat Flywheel. The actual reduction in inertia from stock is much greater than the weights suggest, since the stock flywheel is 1 to 2 inches thick at its outside edge.

The Lightweight Steel Flywheel will bolt up to any pressure plate that will bolt to the stock flywheel (except the Rotary Pickup), and it uses the original bolts. It is also recommend to replace the throw-out bearing during any clutch work to ensure trouble free performance. Also, we recommend replacing the transmission front and rear seal kit when re-installing the transmission to reduce the possibility of leakage.

FC3S TII and FD3S 800HP axle bar upgrade

This is the center bar upgrade for the TII and FD RX-7. The inner and outer c.v. on these cars are made from jis spec, which is very close to 4130 chrome moly (very good). So what is offered is a set of center bars which replaces the part that breaks. The factory bars are brittle and cannot handle the shock factors from higher horsepower rotaries. The center bars are made from 300M material that is specially heat treated, double tempered, destressed, with rolled splines for that extra strength. Ready to install.

Guru Torque Biasing Differential

GURU Racing has produced a automatic torque biasing differential, it is designed to prevent loss of drive to wheels without locking together, while still applying some torque to the slipping wheel.

This progressive action applies all remaining torque to the wheel with the most traction, which is the best design to gain maximum grip under varying track or surface conditions, also leading to improved controllability and cornering compared with a standard LSD unit.

Technical Specifications:

Applications:

• Currently delivered for all Mazda axles plus Ford 28sp
• Suits Mazda models RX2 - RX7 (Generation 1, Series I - III) & MX5
• Suitable for road and race applications

General:

• Large bias ratio through variable torque proportioning
• Less bias change due to less internal wear
• More consistent under various temperature ranges
• No special LSD oil or additives needed
• Improved controllability and drivability

Material:

• All component are precision manufactured
• Manufactured from case hardened Billet AE 8620
