BMW Drivetrain Parts for BMW Z3 (1996-2002)

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

The ZF S5D 320Z 5-speed transmission is known for its robust design, exceptional durability, and impressive power-handling capability. Unfortunately, as these transmissions age, shifter-related issues have become increasingly common. Problems such as difficulty selecting gears, a sticky shifter, or a decline in shift quality are often the result of worn detent springs, pins, and bushings. These components are essential for precise gear engagement and proper shifter centering, making their replacement a critical step in maintaining optimal performance.

Replacing detents requires specialized tools known as "drifts," which are notoriously hard to find. Fortunately, we've developed a complete Detent Tool Kit, featuring five precision-engineered drifts designed for exact fitment in the ZF transmission's detent bores. This toolset makes detent replacement straightforward and minimizes the risk of damage to internal transmission components.

Features

Complete Tool Kit: Includes five precision-machined drifts specifically designed for the ZF 5-speed transmission’s detent bores and caps. Hassle-Free Detent Replacement: Simplifies the process of removing and installing detents with professional-grade precision. Protects Your Investment: Reduces the risk of damaging internal transmission components during service. Durable Construction: Made from heavy-duty 1045 steel for exceptional strength and long-lasting reliability.

Condor Speed Shop took the hard work out of removing and reinstalling your differential! If you've ever taken out your diff, you know how much of a pain it is to get the bolt holes to line up during re-installation. They never seem to line up perfectly, and getting the bolts to go in can be time-consuming. Condor's diff studs are designed to make your life a little easier. The diff will line up and lift right into the holes every time. 38mm studs are used with OEM or regular subframe bushings. 45mm studs are used with the 12mm riser subframe bushings. You'll need to pull the driveshaft to drop the diff. Use thread locker during install. Recommended for street or race use. Kit includes: 4 Studs 4 Washers 4 Lock Nuts

Max Gear is a high-performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drive train. Max Gear virtually eliminates both gear and bearing wear—even under severe squeeze film conditions caused by extremely high loads, sudden shock loads, or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler, and longer without overhauls. It is non-corrosive to both ferrous and nonferrous metals.

They use UHMW in all of their suspension bushings because it is stiff, has almost zero deflection yet also absorbs some vibration. It will outlast other types of rubber or urethane bushings. With their solid diff bushing, you won't have to worry about any more rubbery flex in your diff during hard acceleration.

Condor's Engine Mount Heat Sleeves reflect up to 90 percent of radiant heat. They withstand 1,100 degrees F of radiant heat and up to 450 degrees F of direct heat. The extra protection of the heat sleeves is a perfect fit for street cars, track cars, and other high heat applications. Their mounts withstand temperatures up to 180 degrees F and do not need any heat protection during regular usage, but we recommend the extra protection of their sleeves for all vehicles with high underhood heat temperatures such as turbo and supercharged vehicles. Condor heat sleeves can be easily installed by simply slipping the sleeve around the engine mount and securing using the Velcro tabs. *LISTING IS FOR ONE HEAT SHIELD **Heat sleeve fitment is for Condor Engine Mounts only.

This lightened steel flywheel is specifically designed (and approved) for use in Grand-Am road racing but can also be used as a mild street upgrade if a full aluminum lightweight flywheel is not called for. The Grand-Am flywheel is 20% lighter than stock to meet the rules for the GS and ST classes.Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. The engine revs much faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

Grand-Am approved this flywheel to be used with a factory E36 M3 clutch. This opens up a lot of clutch and pressure plate options but we typically used this with a stock Sachs OEM clutch kit. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches.

Lightweight flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch). In addition to the standard replacement clutches, we also sell Sachs Performance sprung hub clutches that also work with the JB flywheels.

If being used on a 330i 6-speed or Z4 6-speed an additional pilot bearing hub is required. Select your appropriate model and transmission from the list below.

Stock Flywheel Weight = 25.0lbs
JB Flywheel Weight = 20.0lbs

This item fits the following BMWs:
2001-2002 E46 BMW 330i 330ci 5-speed
