The factory BMW S65 dual-mass flywheel is engineered with comfort in mind, catering to the luxury-oriented expectations of the brand’s driving experience. Its design focuses on dampening drivetrain vibrations, smoothing out gear transitions, and minimizing harshness during operation. However, this refinement costs valuable performance. The dual-mass flywheel adds a substantial 27 lbs of rotational mass to the drivetrain, which significantly hinders throttle response and makes rev-matching feel sluggish and disconnected. Moreover, dual-mass flywheels are notorious for being a weak link in modified or high-performance builds and can prove costly to replace when they inevitably fail.

Our Single-Mass Lightweight Flywheel Conversion addresses all of these shortcomings with a purpose-built, lightweight, single-mass design that prioritizes performance. Weighing in at only 19 lbs., this design significantly reduces rotational mass, allowing your S65 to achieve its true motorsport potential!

Features & Benefits:

Precision machined from 4140 HT heat-treated chromoly steel for exceptional toughness, even wear properties, and increased durability.
Material quality promotes even wear across the entire friction surface, prolonging component lifespan.
Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability.
Hardness improves component wear characteristics.
Black oxide coated for corrosion resistance on non-friction surfaces.
Precision balanced to exceed OEM specification (G16 spec to 175g-mm).
Specifically designed to work with S65 OE-architecture clutches.
Optimized step height maximizes clutch clamp load and offers a prolonged service life.
Performance:

8 lbs. lighter than the factory BMW flywheel!
OEM Dual-Mass: 27 lbs.
Turner Motorsport Single-Mass: 19 lbs.
Faster revs
Improved throttle response and acceleration
Allows for a more engaging driving experience and delivers a feeling of direct connection
Installation:

Flywheel Hardware: For added peace of mind, apply Blue or Orange Loctite when installing factory flywheel bolts that do not come with pre-applied threadlocker.

10MM (.39 inch) Wheel Spacer for BMW E24, E28, E30 M3, E31, E32, E34, E36, E38, E46, E60, E63, E82, E83, E87, E90, E91, E92, E93 (E9X), Z3, Z4 Wheel spacers are the ideal solution to resolve a number of fitment and aesthetic problems -- Correct wheel offset issues Achieve a flush fitment instead of the "tucked under" look Clearance the wheel from contact with other components (suspension, brakes, etc). Improve handling and stability by increasing track width A spacer fits between the wheel and the hub assembly and pushes the wheel out by the thickness of the spacer. Our wheel spacers are compatible with almost any type of BMW wheel and are a direct fit to the wheel hub (see below for any fitment notes). Longer wheel bolts or wheel studs are required. This latest generation of the Turner Motorsport Wheel Spacers represents a total redesign of the wheel spacer concept - a ground-up, clean sheet design based on our years of BMW service and motorsports. We took everything we have learned from our service technicians, customers, and race team crew and built the spacer to beat all spacers. We've been in the BMW wheel spacer business probably longer than anybody and when it came time to make our own spacers, a basic spacer design just wouldn't do. We had to make a spacer that is lightweight (for lower unsprung mass), has a tough and durable coating to last through our New England winters, is easily removed (your mechanic will thank you), and is precisely engineered and manufactured for a proper fit on the hub and in the wheel. You won't find a better-engineered wheel spacer on the market! Turner Wheel Spacer Features -- hub-centric design, 1-piece spacer with hubcentric lip precise tolerance fitment thanks to CAD process and CNC mill machine aerospace grade aluminum lightweight but very strong with high resistance to corrosion additional military-spec hardcoat for further corrosion resistance innovative Quick Release pockets for easy removal (better than a chamfered back edge) laser engraved size and part number for easy identification stealthy anthracite or black color extended bolt sets in factory-matching black or bright silver finish available (wheel stud kits also available) Turner Motorsport track and street tested! Made in the USA 10mm Fitment Note: You must be very careful when fitting 10mm spacers to any BMW. Since the depth of the hubcentric lip will vary, you risk bottoming out of the spacer before it sits flush with the hub. This will leave a gap between the spacer and the hub, seriously compromising the strength of the spacer. The lip on the car may need to be shaved down so the 10mm spacer will fit flush on the rotor hat. Extended Wheel Bolts Longer wheel bolts or wheel studs are required for all BMW wheel spacers. Spacers cannot be used with stock bolts. Our extended lug bolts are very high quality and high-grade steel lug bolt (grade 10.9). We offer two finishes to get you just the right look with your wheels - black zinc to maintain a factory BMW appearance or a bright zinc nickel finish to go with polished wheels. Zinc finishes are designed to withstand 700 hours of salt spray testing. Spacer Specs: bolt pattern: 5 x 120 center bore: 72.6mm hubcentric: yes wheel pad size: normal

Turner Motorsport's five years of endurance competition has taught us many things. One was that not all lug-nuts are made the same. While the standard nuts that we sell are great for daily drivers, HPDE events, and club racing, a beefier and more durable nut was needed for the 3-hour, 6-hour, and 24-hour professional endurance races. During the 24 Hours of Daytona, our crew guys made over 80 tire changes in NASCAR-style pitstops. That kind of abuse from air guns and fast work required the "next level" of lug-nut. These nuts are a high-grade steel with a chrome coating and they incorporate several innovative features. The wheel-side of the nut has recessed threads so that the nut has to be square to engage the threads. Without the recess, it's far too easy to start the threads with the nut being crooked. The 19mm head of the nut is slightly rounded to help the socket find its position. The chrome plating that we use is reasonably durable without being excessive. With too much coating, the chipped and worn coating fragments can end up in the threads, leading to all sorts of trouble. Anyone who has used nuts repeatedly knows that the coating is not going to last forever. The constant abuse from air guns will chip it all away. So why add weight and the potential for disaster with excess coating? We did away with most of the danger from that with a lighter coating that still resists the tough environment of the track. Features: Developed for our Grand-Am / Continental race team High grade steel to withstand the extreme abuse of air guns and race conditions Bright chrome plating to help tire changer zoom in on their target quickly and accurately Minimal plating won't result in excess coating wearing off and "gumming up" the threads 19mm hex to prevent rounding off Rounded top for fast socket engagement Recessed threads to aid in fast nut-to-stud alignment without cross threading We recommend using with Turner Motorsport bullet nose dry-lube wheel studs Price is per nut.

Engineered for relentless track abuse, the Turner Motorsport Hydraulic E-Brake Mount delivers direct, uncompromising rear-wheel lockup for the E9X chassis. Forget flimsy universal brackets and custom fab work, this is a purpose-built, high-precision bolt-in assembly developed in-house using advanced 3D chassis scanning and CAD modeling to guarantee exact fitment and maximum leverage.

Constructed around a rigid 11-gauge steel base plate, this mount eliminates structural deflection under heavy loading, ensuring consistent hydraulic pressure when initiation matters most. The heart of the system relies on a 6061 billet aluminum bell-crank pivot paired with Teflon-lined spherical rod ends, delivering instant, slop-free actuation. By orienting the master cylinder longitudinally alongside the shifter, line plumbing and cylinder maintenance remain completely accessible, all while requiring only minimal trimming to the factory console. Built lightweight, durable, and track-ready, it’s the definitive performance upgrade for drivers demanding total chassis control.

Over time, road grime, salt, and moisture take a toll on the factory rear leveling rod. The original equipment often corrodes, seizes, and eventually snaps—or worse, binds up and breaks your expensive headlight leveling sensor. With this issue in mind, ECS has engineered a heavy-duty, bulletproof solution designed to outlast the car it’s installed on.

Instead of brittle OE plastic that degrades and snaps over time, this rod is constructed from high-strength, flexible polyurethane. Paired with corrosion-resistant stainless steel ball studs, it guarantees smooth articulation and prevents the binding that destroys expensive sensors. Precision-manufactured for a perfect, bolt-on fit, this upgrade requires zero modifications to replace your fragile OEM unit.

This is a direct-fit replacement for Genuine BMW part number 37146752797, restoring proper suspension-to-sensor geometry so your headlights adjust perfectly to changing loads and road conditions.
