E30 325i Lightweight Flywheel/Performance Clutch Kit

The best lightweight aluminum flywheel on the market now has a proper clutch to go with it. JB Racing lightweight aluminum flywheels lower the rotating mass of your stock flywheel, allowing your engine to rev quicker, making shifting faster and rev-matching much easier - not to mention dropping driveline losses. The ClutchMasters clutches are a true performance piece with uprated clamp load and options from performance street to racing/track ceramic to take all the power and abuse you can throw at it.

THE FLYWHEEL
JB Racing is one of the best machine shops in the country, used by many professional race teams to do precision machining for engines and other driveline components. Their BMW flywheels are made with the same precision and quality that these teams (including the BimmerWorld World Challenge Touring Cars) rely on, unlike typical units on the market. Standard features include:

• CNC machined flywheel, zero-balanced to eliminate vibration
• Replaceable hardened steel clutch surface, bolted - not riveted on
• Heli-coil inserts for pressure plate don't strip when clutch is replaced
• Factory starter ring gear
• Hardened steel gaul plate keeps the flywheel bolts from damaging flywheel
• Flywheel bolts, pressure plate bolts, and dowel pins included

THE CLUTCH
We have partnered with ClutchMasters for our complete clutch lineup and the result is what you should expect - dependability and performance for the BMW enthusiast.

• Disc material - Depending on your car's use, we offer five flavors for the right amount of grip:
  • ClutchMasters Stage I - Performance Organic - 40% higher holding capacity, excellent for street and track use
  • ClutchMasters Stage II - Kevlar - 70% higher capacity, smooth engagement, very long hard-use lifespan (2-3 times stock)
  • ClutchMasters Stage III - Sintered Kevlar - segmented Kevlar surface, more bite, 110% higher capacity, long life
  • ClutchMasters Stage IV - Ceramic - hard use compound, gives up some smoothness for additional power handling capability
  • ClutchMasters Stage V - Ceramic Puck - road race and hard use package, puck design for more grab and lighter weight
• Pressure plate - We increase the clamping force on the pressure plate by changing the lever action, which adds a minimal amount of pedal stiffness compared to other methods. We also replace the straps with beefier pieces and add an additional layer for good measure - this has proven to be the Achille's heel most pressure plates and is a must for cars that will receive any extended hard use.
  

All kits include JB Racing aluminum lightweight flywheel, clutch disc and pressure plate of choice, and throw-out bearing. Fits all 87-91 E30 325i cars and 89+ 325ix.
