Custom Performance and Race Clutches and Flywheels

Our Clutch Kits are made for us by the leader in aftermarket performance clutch with 8 stages ( Stage1, Stage2, Stage2+, Stage3, Stage3+, Stage4, Stage5, Stage5+). Our Clutches have a stock pedal feel with clamping power that is suitable for every application. Stage5 performance clutches have been tested behind manual transmission vehicles with more than 1000hp and for less modified daily driven clutches, check out the Stage 1-3. The clutch kits include a high clamp load, quick release pressure plate, corresponding stage disc, bearings and alignment tool.

Made from high carbon steel or specially treated aircraft aluminum for superior rotational integrity and warp resistance, the billet flywheels feature a hardened replaceable ring gear, high strength racing bolt kit and SFI certification. Our flywheels are manufactured to an industry leading .001 inch. The billet steel units provide desired momentum for street, drag and large turbo applications, but weigh less than stock for greater reliability and noticeable horsepower gains. The aluminum flywheels are lighter for better performance at road race/Time Attack and autocross events.

High clamp pressure plate, steel-backed and multi-compound woven organic material and high torque sprung hub and disc assembly, bearing and tool kit.

Stage 2: Types of Driving: Street, Drag, Autocross. For all mild to moderately modified naturally aspirated and power adder engines. (Also good for stock power levels and spirited driving when good daily drivability and extremely long life are the goal.) Stock-like daily drivability and EXCELLENT wear characteristics. High clamp pressure plate, pure Kevlar friction material and high torque sprung hub and disc assembly, bearing and tool kit.

Stage 2+: Types of Driving: Street, Drag, Road Race, Rallye, Autocross. For all modified engines making more torque than the stage 2 can support. Maintains stage 2 feel for good daily drivability and offers very good wear characteristics, but provides a higher torque capacity. High clamp pressure plate, composite multi-friction carbon-kevlar material, high torque sprung hub and disc assembly, bearing and tool kit.

Stage 3: Types of Driving: Street, Drag, Drift, Road Race, Rallye, Autocross. For heavily modified street and race engines. Offers sufficient daily drivability with a comfortable pedal feel and quick engagement. Offers good wear characteristics under low and high stress usage. High clamp pressure plate, 4 or 6 puck carbon semi-metallic friction with high torque sprung hub and disc assembly, bearing and tool kit. 6 puck is standard on most applications, but 4 puck can be specified when ordering.

Stage 3+: Types of Driving: Street, Drag, Drift, Road Race. For heavily modified street and race engines making more torque than the st3 can support. Offers good daily drivability and better manageability than the stage 3, with even better wear characteristics. High clamp pressure plate, full-faced carbon metallic friction, high torque sprung hub and disc assembly, bearing and tool kit.

Stage 4: Types of Driving: Drag, Drift, Road Race, Rallye, Circle Track. For heavily modified engines or engines of any modification level being used in the above driving environments, where an instantaneous engagement and light weight are beneficial. Not street-friendly due to harsh engagement. High clamp pressure plate, 3,4 or 6 puck carbon semi-metallic friction with high torque rigid hub and carrier assembly, bearing and tool kit.

Stage 5: Types of Driving: Drag, Road Race, Extremely Modified Engines, needing Twin Plate Clutch up to 680tq. For extremely modified drag race and pulling engines, or applications that call for a ‘slipper’ clutch/progressive torque-induced engagement. These clutches are best ordered as custom configured and should be ordered after providing specific information about the car and it’s purpose. Not street-friendly due to harsh engagement. High clamp pressure plate, rigid iron disc assembly, bearing and tool kit.

Stage 5X: Types of Driving: Drag, Road Race, Extremely Modified Engines, needing Triple Plate Clutch up to 1000tq. For extremely modified drag race and pulling engines, or applications that call for a ‘slipper’ clutch/progressive torque-induced engagement. These clutches are best ordered as custom configured and should be ordered after providing specific information about the car and it’s purpose. Not street-friendly due to harsh engagement. High clamp pressure plate, rigid iron disc assembly, bearing and tool kit.

Torque Converters for Automatic 2.5L

Torque Converters for Street Rods, and Race Cars. Torque Converters are available as a Lockup model, with 2800rpm stall speed. A high-performance or race engine, which makes power at high RPM, needs a torque converter that has a high stall speed. Improve your ETA by 1/2 to 1 sec. Get that power to the road!

These are complete torque converters, no core charge or exchange. You keep your OEM converter.

Delivery is approximately 2-3 weeks.

Switch Operated

Manual-Automatic Shiftronic Shifter Kit

Do you want to shift your automatic like a manual? Need to control torque converter lockup and shift firmness? The device that makes it happen is the Shiftronic Shifter. It's a plug-and-play module that mounts in the cockpit and links directly with your transmission computer harness to provide manual control of up and downshifts, shift pressure and converter lockup.

Once plugged in, you have the option to go to any gear you please, up-shifting and down-shifting when you want. The Shifttronic feature is great for drag racers, rally drivers and anyone who wants positive trans control. The controller also offers you the option of changing how hard the trans shifts, and allows the driver to lock the torque converter on deceleration for real engine braking-like a manual shift transmission.

Shiftronic also has the ability to switch from automatic to manual mode without unplugging the harness, switch operated.

Quaife ATB Differential for WRX

The Quaife is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the car's limits. The Quaife has been proven in everything from SCCA Rally to Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.

In cornering, while accelerating out of a turn, the Quaife biases power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The Quaife also controls loss of traction when the front wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife Differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage whether on the track or on the street.

The Quaife is extremely strong and durable and since the Quaife is gear operated, it has no plates or clutches that can wear out and need costly replacement.
