TDR Engine

	SPEC Performance Clutches and Flywheels

	Specifically tailored for your modified Miata. All clutches come complete with Pressure Plate, Clutch Disc, Throw Out Bearing, Pilot Bearing and Clutch Alignment Tool. We carry three stages depending on your torque requirements (see chart below). For extra savings consider the TDR Dog Pack complete with clutch, flywheel and stainless clutch line.
TDR recommends the Stage 2 clutch for high performance street and track use and or with forced induction for most applications. SPEC clutch provides low pressure clutch engagement compared to ACT clutches making daily street driving much easier on the leg! For engines beyond the Stage 3 level (320 ft. lbs. of torque) we can special order a SPEC Clutch that will meet your needs. We also offer a lighten or aluminum pressure plate option that will reduce up to 3 pounds from the clutch flywheel assembly (more info here) Three items TDR would suggest during your installation. Upgrade to the SS braided clutch line for a more linear engagement. Second, order the TDR transmission seal and gasket kit and both shift boots. These items usually need to be replaced during a clutch job. And thrid. TDR recommends that you use Red Line MTL or Red Line MT-90 (2 quarts) for the gear box and 75W90 High Performance Gear Oil (1 quart) for the differential.

Lightweight and Aluminum Pressure Plates	Street, drag, drift, road race, autocross	For years lightweight flywheels have been used to transfer energy from the engine to the ground more efficiently, resulting in horsepower and torque gains, quicker revving and less internal engine wear. SPEC offers two methods for reducing mass, a drilled and lightened steel pressure plate and their NEW aluminum pressure plate. The SPEC aluminum pressure plate offers the same benefits and the reduction in mass as a lightweight flywheel, but is more effective since the pressure plate extends further from the crank flange. They can be used with OE flywheel or in conjunction with a lightweight aluminum flywheel for a more drastic improvement
