Turner Motorsport for BMW 3 Series E90 (2006-2011)

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!

By popular demand, our shoe-gripping Turner Motorsport pedal set is now available for E82 1 series and E9X 3 series with automatic transmission. These pedal covers feature pyramid shaped spikes on the brake pedal, which actually BITE the soles of your shoes PERFECTLY, creating the ultimate (and unbeatable) friction surface where you want it. The throttle pedal is left smooth, so that your foot can roll on and off the gas smoothly. The automatic transmission set includes 2 pieces -- one brake pedal and one throttle/gas pedal.

Our pedals are anodized for a beautiful cosmetic finish that resists chips and flaking. Stainless steel hardware is included, as well as a basic installation guide (professional installation always recommended). These pedals are for left-hand drive (LHD), automatic transmission BMWs only (sequential manual transmission cars should use the manual transmission set).

Also available in 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.

There are a few reason having a catch can is an upgrade for a vehicle, from a separator system that no longer works to one that was never there. 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 and carbon buildup 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 oil mist can in the intake charge even increase the risk of engine damaging detonation. 

With direct injected engines this problem becomes more prevalent, and the N54 in your 135i or 335i is no exception.  We're seeing a lot of N54 powered cars with drivability and performance issues due to significant carbon buildup in the intake ports and backs of intake valves.  The “factory fix” is a walnut blasting service that commonly needs performed every 30,000 to 70,000 miles.  Don't be part of this statistic!  Our shop recommends an oil catch can be installed in-line in the PCV system to help reduce the build-up of performance robbing deposits and greatly reduce the need for costly walnut blasting service and related repairs in the future.

​ The catch can utilizes a strategically designed 4 chamber baffle plate system engineered to create multiple changes in the direction of airflow to cause oil droplets to fall out of suspension, maximizing the efficiency of the PCV air/oil separation.  A dipstick is integrated into the cap so you can monitor the oil level, and the can is easily serviced.  At each oil change simply unscrew the canister and empty the trapped oil with your regular used oil.  The Turner Motorsport Oil Catch Can is CNC machined from billet 6061-T6 aluminum and with a stealthy black anodized finish for lasting durability and appearance, and includes everything needed for an OEM-like fully reversible installation. Another feature the Turner catch can has is the ability to add on a drain kit so you no longer have to fumble around getting the fill can out of a tight space. The drain can be run down to the belly pan of your car so draining can be done at the same time you change your oil or anytime in between.

Oftentimes, the first thing you will notice about your manual BMW is that the stock shifter throws are miles and miles long. We developed our short shifter kit as a solve for this common complaint about manual transmission BMWs. Our new short shifter kits are the culmination of years of research and development - we went back to the drawing board several times throughout the design process, in efforts to release a product that really stood out from the rest of the short shifters on the BMW market. We set out to design the perfect shift kit for your BMW. Now we realize perfect is a subjective term, so we gave our short shifter a wide range of height and throw adjustability. This wide range of adjustability allows you to easily make adjustments from the cabin of your BMW by just removing your shifter boot and using small hex head keys.

We made our short shifter for all of you. The weekend warriors, the trackday monsters, and even the daily drivers. We wanted to make something that made sense for any BMW enthusiast. For those who want to drive your car to the track, drive some hotlaps, and then drive back home, we developed a rally lever extension. Our rally lever extension allows you to keep your hands close to the steering wheel through shifts, in efforts to quicken shifts and reaction times on the track. The rally lever comes off and on in seconds with the unique locking design we engineered. After your track day win, you can easily swap back to the short lever for more comfortable daily driving.

Installation of this kit is one of the easiest to take on compared to the competition - our custom bearing cup allows for easy installation from inside of the car (on applications that use the stock shifter arm).

If you're installing racing rear shocks with a spherical bearing end you will need this adapter mount for the top of the rear shock. Spherical or rod-end bearings are common on race shocks but they are somewhat universal and mounts are not usually included. We designed and engineered these mounts for our E9X M3 and E90 328i IMSA/CTSCC racecars. Our cacing upper shock mount is machined out of aircraft grade aluminum with a tough anodize finish and high grade hardware. Due to the wide variety of spherical bearings and rod-ends found on race shocks, the bushing kit is sold seperately (see chart for bushing sizes).

In an effort to design products that are more appealing to the daily driver we engineered these Delrin protection plates based on our own experience with bumper & splitter damage on our own M3's. The aggressive design of the E9x M3 bumper makes it virtually impossible to not have contact at some point of the bumper, from parking curbs to slight inclines making your bumper or carbon splitters look ugly. 

We decided to use Delrin with our design due to its durable features, the hardness of Delrin will reduce the amount of visible scratches on the surface and giving extra support under high speed driving conditions. Our protection plates are offered to cover both carbon splitters and the bare bumper with an exact fitment and slightly aggressive option for both situations.

*For use with stock bumpers without the carbon fiber splitter upgrade.

Due to weak plastic construction, the factory plastic crankcase ventilation breather hose is known to fail. After years of exposure to piping-hot engine bay temperatures and chemical-laden oil vapors, the corrugated plastic tubing can crack, crumble, or fail altogether.

We set out to bulletproof your N52 CCV system with a durable silicone breather hose, designed to provide a comprehensive upgrade and permanent replacement for the factory plastic hose. By replacing the flimsy, heat-hardened OEM plastic hose with a four-ply fluorosilicone hose, you'll experience peace of mind knowing your N52 is free from the inevitable return of oil leaks, vacuum leaks, and drivability concerns that would have been.

This breather hose is found at the front of the engine, and is used to connect the oil separator to the valve cover. It replaces OEM part number 11157522931.

Features:

Silicone construction ensures a durable replacement that is sure to outlast OE plastic
Designed as a direct replacement for the factory breather hose
Retains heating function and OE electrical connector
Design:

Four-ply wire-reinforced fluorosilicone hose is designed to resist degradation due to exposure to oil vapors
O-rings are pre-installed in OE connectors for a lasting seal
Includes pre-installed zinc-coated hose clamps for durability and corrosion resistance
Product Development:

Our Silicone CCV Hose Upgrade was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for 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 modelling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

If you own an M57-equipped BMW, you already know this twin-turbo diesel powerplant is an absolute torque monster. What you might also know is that all that low-end grunt and high-compression diesel vibration wreaks absolute havoc on your accessory drive system.

From the factory, both the E90 335d and E70 X5 35d utilize a rigid alternator pulley. With each cylinder's fire, the crankshaft experiences a violent micro-acceleration. Because the alternator has a heavy internal rotor spinning at high speeds, it wants to keep spinning at a constant rate. When the engine suddenly slows down (even minutely between firing cycles), the alternator fights the belt. This constant tug-of-war results in extreme stress on your engine's belt-driven components. At best, it’s an annoying, unrefined chirp at idle; at worst, it’s a ticking time bomb for your expensive harmonic balancer.

To solve this issue, many enthusiasts choose to run a clutched alternator pulley (also called an overrunning alternator pulley). A clutched pulley allows the alternator to "freewheel" or coast when the engine slows down, completely isolating its rotational inertia from the belt drive to prevent component wear. While the N52's clutched pulley (12317560483) is a straight bolt-on, the offset is incorrect for the E90 335d's accessory drive. Thankfully, our engineers designed this zinc-coated spacer to provide the precise amount of spacing needed to perfectly align the new pulley with existing belt drive components.

• 55MM, 75MM, 90MM LENGTHS
• Black phosphorous corrosion resistant coating
• "OEM" appearance
• Full-length threads for more nut engagement in tight spaces
• Long shank for good brake rotor alignment
• Heat-treated aircraft quality alloy steel

Wheel studs are among the safest and most beneficial upgrades you can make on a track car. Not only are wheel studs safer than wheel bolts but they make changing wheels/tires much easier. One of the frustrating things about installing your wheels on the hub is that it's difficult to line up the wheel on the bolt holes. As wheels get larger but also heavier it's even more trouble. Add in a wheel spacer and the task is twice as hard. BMW does produce a wheel alignment pin for this purpose but if you're changing wheels often a stud conversion is the better way to go.

These wheel studs are the same as our hugely popular Bullet Nose studs but with threads along the full length of the stud. This gives you more threaded area for tightening wheel nuts or allows the use of a closed-end wheel nut. These also have a more OEM appearance. Although these are a lower cost version of our Bullet Nose studs, they are every bit as strong, durable, and safe. The Bullet Nose is an upgrade because it's easier to install and almost impossible to cross-thread a nut.

Not all wheel studs are created equal. We don't take a manufacturer's generic wheel stud from their catalog and call it our own. Turner Wheel Studs are designed to our own specifications and manufactured for us exclusively. Beware of cheaper studs on the market! We have seen other studs similar to our own designs that are not a true BMW fitment. There are differences that we have ironed out over our years of selling wheel studs for the BMW market. Our stud prices may be slightly higher than the rock bottom prices on the web but we promise that it's a higher quality.

Sold per stud.
