Location: Front Type: Street, Stage 1 Bearing: captive-ball fully encased in polyurethane
These front adjustable camber/caster plates will replace your stock front upper strut bearing. The KMAC plates are a 'floating' design so camber and caster are adjusted together. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. Since these replace your stock strut bearings they are designed to work with a stock-type spring only. And when installed correctly will not significantly alter ride height. Adjustment is easily done by loosening the three nuts on top of the tower and sliding the camber plate into the position you want, then re-tighten the nuts. These mounts can be installed two ways - for camber correction or swapped side-side for increasing negative camber. Detailed instructions included.
Note: suspensions vary from manufacturer to manufacturer. Turner Motorsport cannot be responsible for fitment issues caused by non-stock or specialized coil-over suspensions. As with any race-derived component, additonal fabrication may be required.

Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.
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. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, 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. Again, the difference is huge as you watch the revs build 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.
The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can also be rebuilt with a new clutch contact surface - you don't have to buy a new flywheel.
Aluminum 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).
This JB flywheel replaces the stock flywheel and can be used with either the stock 228mm or stock 240mm clutch discs. Depending on the model you may have either clutch size in your car but this flywheel is compatible with both. You can install a 240mm clutch as a mild upgrade.

This lightweight aluminum flywheel w/ Heavy Duty "sprung-hub" clutch package is the best-engineered solution for E46 325 and 330 models with the 6-speed transmission, Z4 2.5/3.0, and Z4 M Roadster and M Coupe. Instead of picking a clutch from another car that may or may not work at all, the engineers at JB Racing have taken all of the guess work out of this upgrade and incorporated a Sachs sport sprung-hub clutch with the correct pressure plate and combined it with their most-popular aluminum lightweight flywheel. The Sachs HD clutch disc has a sprung hub to minimize noise and vibration and organic linings to give the feel and engagement of a stock clutch. Mixing and matching of the incorrect clutch, pressure plate, and flywheel components can lead to inconsistent engagement and feel -- why make your clutch feel worse?
In addition, the Sachs HD pressure plate will clamp with greater force -- allowing approximately 350 ft-lbs of torque, which makes it an obvious upgrade from the stock clutch kit. And with the aluminum flywheel weight savings is substantial over the stock dual-mass flywheel - which allows your motor to spool up faster and transmit more HP to the ground.
Because Sachs is an OE supplier to most German cars, replacement parts are just a phone call away. This kit uses the stock throw-out bearing (included in the price).

Location: Front Type: Street/Track, Stage 2 Bearings: main PTFE-lined pillow-ball bearing suspended in polyurethane; self-lubricating radial axial bearing/bushing in upper spring plate Springs: includes OEM size upper spring perch, 60mm upper spring perch, and 2.5" upper spring perch
The Stage 3 KMAC plates are a mixed track and street camber/caster plate meant to be used in a variety of suspensions and setups. Since there is less bushing than on the Stage 1, more noise and vibration will reach the driver. The adjustment design is similar to the Stage 1 with a floating mount that sets camber and caster simultaneously. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. These plates can work on both coil over and stock-stype suspensions and upper spring perches are included for OEM springs, 60mm, and 2.5" coil over springs. The upper perch assembly incorporate a self-sliding radial bushing that allows the spring to spin during its travel instead of bind. This reduces tension on the spring and helps reduce noise and spring 'popping' noises. Bearing inserts, spacers for correct articulating angles, and 3 sizes of upper nut adapters included. The urethane bushings and bearings are replaceable if they wear out. These are designed mainly for adding negative camber for improved handling and not for camber correction back to stock settings (see Stage 1 kit). Basic instructions included but professional installation is required.
Note: suspensions vary from manufacturer to manufacturer. The proper stacked height and clearances are required. K-Mac includes bearing adapters, spacers, and various top nuts but it is still the responsibility of the installer to ensure a correct and safe fitment. As with any race-derived component, additonal fabrication may be required.

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.
