Weight reductions in rotating mass in  the drive train are effectively worth more than their weight in reducing inertial power loss. TC Kline Racing offers JB Racing flywheels exclusively. JB Flywheels are aluminum for light weight, has a steel ring gear for durability and are designed to work with OEM as well as performance clutches. 

Each of our flywheels include:

• Complete CNC machined aluminum flywheel
• Replaceable hardened steel clutch disc surface
• Dowel pins and pressure plate hardware
• Starter ring gear heat shrunk and bolted
• Hardened flywheel bolt ring
• Premium 10.9 grade installation bolts
• Each flywheel assembly is Zero-balanced

Sachs Racing Sintered  Disc- This premium metallic lined lightweight racing disc offers the ultimate in grip, durability and track performance. Designed for high horsepower and track use applications. The aggressive engagement nature of this disc makes it marginally suitable for street. See bottom of page for Ultra-Lite 5.5” Racing Clutch assembly.

 ULTRA-LITE Racing Flywheel / Clutch System- are designed to enhance vehicle performance by reducing the static flywheel weight and more importantly, the Moment of Inertia (MOI) to near minimum which allows the engine to "rev" quicker thus increasing the vehicle's acceleration rate. These flywheels are designed for off-highway competition usage only and utilize reduced diameter multi-disc racing clutches. These clutch systems require a properly installed and adjusted clutch pedal stop to control clutch pedal travel. These flywheels and clutch systems are not suitable for street driven vehicles.

- Complete CNC machined UL aluminum flywheel
- Racing 5.5” dual disc clutch - 5.5” Performance  pressure plate                  
-Throw-out bearing w/ custom JBR bobbin                       
- Replaceable, hardened steel friction surface                                          
- Pressure plate mounting hardware                                     

- Helicoil inserts installed as required
- Starter ring gear heat shrunk and bolted
- Hardened steel flywheel bolt ring
- Premium 10.9 grade installation bolts
- Zero Balanced 

Differentials ­ TC Kline Racing can greatly enhance the functionality of your BMW limited slip unit by increasing the ramp angles to increase lockup under acceleration. Our race track experience has shown us that by altering the internal ramp angles, rather than simply shimming the clutch pack (as most rebuilders do), we are able to provide approximately a 30% lockup (very near the stock setting) entering a turn and approximately 70% under full acceleration. These settings make for optimal handling in all situations.  Available for all models.

RE Finned Diff Cover ­ Fashioned after other high-dollar alternatives, the Rogue Engineering diff cover holds an additional 1.5 quarts of differential oil and includes a port for temperature sensor (for monitoring).  By being able to cool the differential properly, increased clutch-pack life can be expected.
