Red Line 75W140 is a full synthetic high-performance gear oil that is an excellent substitute for expensive factory fluid and an upgrade over off-the-shelf economy fluid. Red Line thoroughly evaluates the manufacturer's recommendations and only makes a fluid recommendation if their own product meets or exceeds the original specification. In many cases the Red Line synthetic will outperform the factory supplied fluids. We've been using Red Line Oil in our BMWs since we opened in 1994 and it remains our best selling BMW differential fluid. 75/140 is a specialized weight used for BMW M3, M5, and M6 models with the M Variable limited slip diff (all M models since 2001). Red Line fluid is used in nearly all E46 M3, E92 M3, E60 M5 we service as well as the custom differentials that we sell. It's great for the street where the polyol-ester base has natural lubricity and friction modifiers lead to smoother and quieter operation with lower operating temps than the factory fluid. We also use it in the track cars we build and prep. It may also be used in other specialized situations where a regular 75/90 will be too thin at elevated temperatures and your diff builder has approved a heavier weight oil.
Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360. An alternative to the very expensive factory BMW SAF-XJ+FM diff fluid (#83222282583).

The Dinan short shifter provides shorter shift throws with a crisper and more precise feel than a stock shifter. Instead of retrofitting a stock BMW lever, with all of its deficiencies, Dinan has engineered this billet aluminum shifting system. Special features engineered into this unit include a two piece fully isolated stick assembly, exclusive integrated and dampened pivot cup with self lubricating pivot ball, counter balanced to reduce effort and exclusive polymer "Iglide" T-500 lower pivot bushings that are impervious to contamination. Featuring an adjustable pivot, which allows this shifter to fit both standard and M Series applications. All of this combined with a simple straightforward installation provides a professional level shifter. Provides a 30% throw reduction in E82 128i/135i, E9X 325i/328i/330i/335i, and E60 530i/545i/550i.
For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty.

When it's time to replace your car's clutch, you face a crucial decision: upgrade or stick with stock? In many cases, upgrading is the preferred choice, especially when you pair the right clutch with a single mass flywheel. The secret to achieving the perfect blend of performance and driving experience lies in selecting a sprung hub clutch. This option allows you to enjoy the advantages of a single mass flywheel while eliminating issues like noise, vibration, and harshness (NVH), ensuring an outstanding driving performance.
The BMW E9X 335i BMS Differential Support Bracket Brace - Small Case is a high-performance upgrade designed to enhance the stability and durability of the differential mount. Turner Motorsport offers this precision-engineered brace to reduce flex and movement of the differential, ensuring improved power transfer and handling. Ideal for high-performance driving or track use, this brace helps maintain proper alignment and extends the lifespan of your differential components.
SPEC's Stage 2 clutch features a full faced pure Kevlar disc complete with steel backing. This lining offers outstanding drivability like the Stage 1 kit, with an increased torque capacity and a longer life. The hub is double sprung with built-in spring reliefs for flexibility, along with heat treatment for added strength and durability. This clutch is best served in any situation from daily driven on the street, to drag or autocross racing events.
Kit includes:
Pressure plate
Clutch disc
Pilot bearing
Clutch Release Bearing
Clutch Alignment Tool
Clutch fork
Designed to be used with billet single mass flywheel
| #SB533H-2 Variant | Use | Comments |
| "Sport" SPEC steel flywheel | daily driving; occassional drag strip | Use this with the SPEC steel single-mass flywheel. The clutch will be stiffer than the factory design but it will grab harder and stay connected with far less chance of slippage. The engagement point is changed but most drivers adjust within the first 100 miles. The failure-prone dual-mass flywheel is eliminated and a steel single-mass is used instead. Expect more noise and vibration from the steel but better reliability and slightly better performance. |
| "Super Sport" SPEC aluminum flywheel | more drag strip than street | Use this with the SPEC aluminum single-mass flywheel. The clutch will be stiffer than the factory design but it will grab harder and stay connected with far less chance of slippage. The engagement point is changed but most drivers adjust within the first 100 miles. The failure-prone dual-mass flywheel is eliminated and a lightweight aluminum single-mass is used instead. Expect a lot more noise and vibration with aluminum ("gearbox rattle") but better reliability and better performance. The engine will rev a lot faster too. |

Synthetic D4 ATF is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. ATF D4 is similar to Red Line's MTL formula and can be used in many BMW manual transmissions where MTF or MTF-LT2 is called for. The D4 ATF provides significantly improved gear protection than most OEM oils. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure.

This is Red Line's latest synthetic transmission fluid that is compatible with BMW's MTF-LT3 transmission fluid. This is the transmission fluid used in both manual and automatic transmissions since the mid-2000's. To confirm, check the decal located on the side of your transmission. Price is per quart.
Synthetic D6 ATF is a lower viscosity version of the D4ATF and is designed for better fuel efficiency in CAFE testing. Dexron VI requires a different approach to a conventional ATF formulation. Rather than beginning with a 7.5 cSt fluid and allowing a viscosity loss in use to drop to 5.5 cSt, the Dexron VI fluid requires a starting viscosity of less than 6.4 and a final drop to no less than 5.5 cSt. Red Line D6 will drop to no less than 6.1 cSt. Since the final viscosity after use of these fluids are similar, Dexron VI fluids can be used where Dexron III fluidswere previously recommended (with the exception of some manual transmission applications, our customers report).
D6 ATF also provides significantly improved gear protection and will provide a GL-4 level of gear protection. The balanced frictional characteristics provide smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure.
Experience unparalleled performance with Red Line CV-2 Grease, expertly crafted to endure extreme temperatures and pressures found in high-performance wheel bearings and CV-joints. This premium grease surpasses both conventional and synthetic options with its exceptional high-temperature stability, superior extreme-pressure protection, and water resistance. Operating effectively in temperatures spanning from -100°F to 500°F, it offers outstanding oxidation and corrosion resistance, minimal evaporation and oil separation, and has minimal impact on rubber seals. Expect a remarkable 200% to 800% increase in bearing life due to the exceptional extreme-pressure performance and synthetic oil fluidity. Its red moly compound outshines black moly disulfide lubricants, ensuring superior lubrication.
Red Line CV-2 Grease finds application not only in automotive settings but also in industrial environments. It excels in high-temperature alternator bearings, high-speed ball bearings, conveyor bearings, worm gear drives, servo mechanisms, and other scenarios prone to fretting wear and corrosion. Its consistency and extreme-pressure performance endure high-temperature and high-shear conditions, extending the performance life of lubricated components. Despite darkening after high-temperature use, its efficacy remains unaffected. While compatible with some petroleum-based greases, it's recommended to clean out old grease thoroughly for optimal lubrication performance and to avoid grease incompatibility.
