Single piece 6061 construction, optimized cooling, provisions for temp sensor and external cooler!

Built to last, made from a single piece of 6061 billet aluminum with a rugged and good-looking hard-coat anodizing our diff cover can handle anything you throw at it. Not only is it an absolute masterpiece to look at but this billet diff cover checks all the boxes for features needed. Reinforced mounting ears for strength and stability, never again will you break an ear off your diff cover like the factory units are known to do. Each ear is unified with the one-piece billet cover and features added material for the highest durability possible. This diff cover is cool, literally, the entire construction was designed with optimized cooling in mind. Internal fins are strategically placed serving as effective heat sinks for optimal heat dissipation. This ensures stable temperatures, promoting longevity for both the fluid and your differential. Additionally, the internal design ensures continuous oiling and lubrication of the ring gear, maintaining its stability and preventing fatigue by controlling heat more effectively. An internal baffle at the cover's corner helps maintain proper pressure and prevents cavitation.

All of the OEM features were retained along with the upgrades. The mounting surface was designed to be compatible with both the OEM gasket or RTV of your choosing, some people don't trust the gaskets and we get it. Factory bushing geometry allows you to use any E46 diff busing including rubber, poly, and even solid mounts. The drain and fill plugs on the diff cover are upgraded to -6AN using the provided high-pressure fittings with replaceable o-rings. The drain and fill plugs can now also be used for expanding to an external oil cooler allowing you to further expand the fluid capacity for optimized cooling and service intervals. To keep an eye on things from the driver seat is 1/8 NPT provision for temp sensors, this product from Turner has you covered at every turn.

Why the upgrade?

Upgrading to our Billet Differential cover gives you the strength you need to push your car to its limits. In addition to its enhanced strength, this differential cover includes numerous other upgrades and conveniences. These include increased capacity, improved cooling and lubrication for the ring gear, upgraded fill and drain plugs, and the option to expand an external oil cooler for extreme motorsport usage. Designed to complement both upgraded daily drivers and extensively modified track cars, all while looking good in the process.

Product development:

Our Reinforced Billet Diff Cover was designed, engineered, tested, and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

Here at Turner we understand the importance of an upgrade that will get the results you need on the track and still be tolerable on the drive around town. When it comes to control arms on the track, making them as stiff as you can (usually using solid mounts) is the best way to increase your driving precision by eliminating the deflection of rubber. The next best thing to create a balance would be to stiffen up the control arm with polyurethane, giving you the option of a more stock like feel with 80a or closer to the solid feel with 95a durometers. These poly bushings will give your control arms a direct connection between your suspension and the body of the car eliminating the slop felt under take-off and braking so you feel more in control of your vehicle. 

This item fits the following BMWs that use a centered-style bushing: 

1999-2005 E46 BMW 323i 323ci 325i 325ci 328i 328ci 330i 330ci - not for xi models 
2003-2008 E85 BMW Z4 2.5i Z4 3.0i Z4 3.0si 

These aluminum pedals were designed with one thing in mind -- performance. We wanted a pedal set that gave us the grip EXACTLY where we wanted it: MASSIVE GRIP on the brake and clutch pedals, and far less grip on the accelerator to allow the right foot to better slide/move during heal-toe braking. This set surpasses all others in this area, giving your BMW's foot operated controls a more tactile feel and response. The brake and clutch pedals feature pyramid shaped spikes, which actually BITE the soles of your shoes PERFECTLY, creating the ultimate (and unbeatable) friction surface.

These pedals are 100% MADE IN THE USA, and are CNC machined from aircraft quality aluminum billet to perfectly fit your BMW. There's no rubber to wear out, and no cosmetic finishes to chip or flake off. Stainless steel hardware is included, as well as a basic installation guide (professional installation always recommended). These pedals are for left-hand drive (LHD), manual transmission BMWs only (including SMG and DCT sequential manual gearboxes -- on these cars, you will only use one of the included clutch/brake sized pedals).

Now available in (optional) black anodized! The same shoe-gripping performance as our standard "naked" aluminum racing pedals, but with an added black anodized coating, for a stealth black finish. We always recommend the naked metal pedals for harsher/race type use, as all cosmetic finishes will eventually degrade over time. But for those looking for the black-out look, we can now accommodate! To add this option, simply choose your selection below.

The E46 M3’s high-revving S54 engine deserves an exhaust note that matches its motorsport pedigree. Developed with precision acoustics in mind, this comprehensive exhaust package delivers the ideal blend of high-rpm rasp control, flow performance, and switchable sound volume. Unleashing exotic tones every time you hit the throttle

By pairing our Resonated Equal Length Section 1 with our Valved Stainless Steel Rear Exhaust, this system equalizes exhaust pulse timing to produce a clean, exotic tone. Open the valves via the included Bremman wireless control kit to bypass restrictors for maximum flow on the track, or close them for subtle street cruising. Engineered for a direct fit, this kit comes complete with track-grade HJS hangers and brand-new exhaust hardware to replace worn factory components.

Modern day emissions regulations require the use of a closed crankcase ventilation (PCV) system to recirculate combustion blow-by gases from the crankcase back in to the intake to be burned.  Unfortunately, these blow by gases contain water vapor (which is a byproduct of combustion) and pick up oil mist from and the windage cloud and cam lubrication system as they travel through the crank case.  Due to less than 100% effective air/oil separation in the stock PCV system, some oil mist and water vapor gets carried back to the intake tract and over time cause oil deposits in the intake manifold, intake ports, and on the back of intake valves.  All will eventually lead to poor performance and reduced fuel economy, and the presence of this oil mist in the intake charge may even increase the risk of engine-damaging detonation. 

With forced induction, track use, and/or extended high RPM usage, these symptoms increase as the factory PCV system is overwhelmed, and a catch can becomes a must for your E46 M3. This kit is a direct fit making this an easy reversal if desired as well as maintaining a clean appearance by utilizing the open "smuggler's compartment" on the passenger side of the engine bay.

A combination of billet fittings and AN lines for an upgraded and serviceable crankcase vent hose. Attaches between the oil separator and the CSL air box.

The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition. The factory hoses offered by BMW are plastic and will yield the same results of becoming brittle and damaged over time.

We have created a full motorsport-style solution with our CSL Crankcase made from machined 6061 billet aluminum with AN-style fittings and nylon fiber braided lines. This is a fully serviceable replacement that will outlast every one of the OEM replacements. Our AN crankcase line can be used to replace the factory brittle hose to ensure your S54 is free from vacuum leaks and performing properly.

The E46 is by no means a very old car. But more and more E46s are seeing track use or being converted to all-out track cars. And the odometers aren't rolling backwards. With age, mileage, and hard use the chassis will develop weak points that threaten the overall integrity of the car. When suspension points and subframes start to rip from the car, it puts the driver and anyone else at a serious safety risk. Not to mention the obvious effects on the performance of the car. TMS has developed reinforcements for the most-common weak points in the E46 chassis. With these kits in place you can be sure that your car spends less time on a body rack and more time on the race track. Included in this package are all of the reinforcements we developed for the E46:
 

• front subframe
• front strut towers (not applicable for M3)
• rear shock towers
• rear camber arms
• rear sway bar / swaybar tabs (not applicable for M3)
• rear subframe
