Turner Motorsport for BMW 3 Series E46 (1999-2005)

Stock rubber front control arm bushings are designed to allow significant fore/aft movement of the front wheels to help absorb road impacts.  This soft flexible design maximizes daily driving comfort and helps to add the “luxury” feeling to your BMW, but it is far from ideal for the performance or racing enthusiast that is looking for optimal handling and braking performance.  Being a bonded rubber bushing that is constantly twisting and deflecting when in use, stock rubber bushings really take a beating and often fail prematurely, resulting in further degraded handling, braking shimmy or even clunking felt under your feet.

In the past, the only upgrade option to improve handling of your E46 M3 was to replace the stock rubber with poly bushings, or delrin bushings that wear prematurely and are not serviceable or rebuild-able.  While well-designed poly bushings can vastly improve handling characteristics and offer good road feel with minimal increase to NVH, they are still a compromise when it comes to ultimate handling and braking performance.

Introducing the new Turner Front Control Arm Spherical Bearings!  The Turner engineering team set out to design a no-compromise solution that requires no modification and offers instantaneous cornering and braking response.  Our control arm bearings utilize a unique grease-able spherical bearing that is both serviceable and replaceable, with integrated dust seals to help keep dirt and moisture out.  This bearing offers considerable improvement in both precision and durability compared to other unsealed poly and delrin bushing inserts previously available, which can wear prematurely due to contamination.  The bearing assembly utilizes the highest quality materials, precision machining quality, and components to ensure a perfect fit and longest lasting component life possible.

The result is the ultimate in terms of low friction, no binding, and no unwanted deflection, as well as exceptional steering precision, turn-in response, and direct braking feedback with minimal increase in NVH.  These spherical bearings are a must have for any track car, but are also completely street-able and are a great upgrade for any enthusiast that enjoys spirited driving.

Features:

Our unique and carefully designed front lip for the E46 M3 focuses on enhancing the car's aesthetics while preserving its natural beauty.

This aesthetic piece was crafted to stand out from other options available on the market by incorporating design elements that draw inspiration from the stock bumper but reimagines them in a way that sets it apart. Rather than overcomplicating the car's body styling, the goal was to seamlessly integrate the front lip with the existing design. This approach aims to enhance the car's body styling rather than overshadow it.

This versatile design is suited for both track use and everyday driving on the streets. Our E46 M3 front lip was designed to strike a balance between uniqueness and performance oriented aesthetics, while complementing the car's existing design. This is a clear cut choice front lip for someone looking to enhance the look of their M3.

Once you see your M3 with this front lip from, you will no longer think the front end is complete without it.

Unlock the full potential of your S54’s valvetrain with our High Performance Cam Followers/Rocker Arms, built for precision, durability, and reliability in high-revving performance engines.

Crafted from forged chromoly steel and finished with a diamond-like carbon coating, these cam followers are engineered to deliver exceptional strength, reduced friction, and outstanding wear resistance, ideal for demanding street or track use. Each unit is precision-ground for consistent clearances and smooth, stable valvetrain motion at all RPMs. Despite heavy-duty construction, our design retains the same weight as the factory rocker arm, preserving OE valvetrain geometry and balance while offering superior longevity and performance.

Rocker arms wear in conjunction with the camshafts, meaning the two must be replaced simultaneously. Aftermarket and performance camshaft options (Schrick, CAT-Cams, etc.) are typically ground from softer blanks and, as a result, cannot be used with factory rocker arms. We tested our performance cam followers with aftermarket camshafts to validate compatibility, ensuring smooth, reliable, and safe operation under demanding conditions.

Features:

Forged chromoly construction for maximum strength and durability Diamond-like carbon-coated surface reduces friction, extends service life, and permits compatibility with aftermarket and performance camshaft options Precision-ground tolerances ensure consistent and quiet operation OEM weight match maintains valvetrain balance and reliability Superior wear resistance for performance and endurance applications NOTE: Rocker arms are wear items and must be replaced alongside a new set of camshafts, regardless of profile or manufacturer. Installing a new set of rocker arms onto a used set of camshafts is NOT recommended.

Drop 10 lbs and replace your midpipes/resonator for a free flowing X-Pipe to get a smoother sound and decreased back pressure!

An X-Pipe can do wonders for your engine for performance and sound. Exhaust gasses come out of your motor in pulses from each individual cylinder, with a cross-over or x-pipe the exhaust gasses meet in the middle and combine. The result of the combining gasses is a smoother path leading to lower amounts of back pressure, a more free-flowing exhaust and leads to increase power and response. Combine with a new rear muffler for best results!

BMW's straight six motors have been referred to as sounding like chain-saws, and being "raspy" or "metallic". Transform your exhaust with our mid section exhaust with an integrated x-pipe to smooth out your exhaust tone and enjoy the sound of your M54! The mid section x-pipe comes with new hardware for connection to the downpipes and includes superior exhaust sleeves to slide over your factory rear section.

Rear Axle Carrier Panel (RACP) failure is a well-documented issue that plagues all BMW E46 models. Due to thin sheet metal mounting, the forces applied during cornering, acceleration, and braking create stress fractures in the carrier panel, resulting in large cracks or breaks that risk the structural integrity of your chassis. To fix this issue, many enthusiasts opt to install weld-in reinforcement plates on the underside of the RACP. While this remedies the formation of additional stress cracks and adds rigidity to failure-prone areas, it does not prevent the entire carrier panel from flexing during high-performance driving.

Our all-new Rear Subframe Reinforcement Brace is engineered to add structure to the E46's rear chassis under high-stress conditions, eliminating the common weak points in the RACP while providing the confidence you need for performance driving. Don't let chassis flex limit your car’s potential—upgrade your E46 with the Turner Motorsport Rear Subframe Reinforcement Brace today!

How It Works:

During performance driving, the Rear Axle Carrier Panel (RACP) must react the forces of longitudinal and lateral accelerations. During forward acceleration, the differential transmits torque through the subframe to the RACP, forcing the rearmost subframe mounting points downward. This downward movement flexes the carrier panel, reducing its ability to handle torque efficiently. By linking the rearmost subframe mounting points to the rear shock towers, downward flex is restricted, resulting in improved torque transfer and stability. Alternatively, high-grip cornering generates lateral acceleration (side-to-side) forces across the RACP. Similar to how a rear strut brace functions, connecting the rear shock towers helps to counteract these forces. Adding the subframe to this connection further reduces lateral loads, eliminating side-to-side flex and enhancing overall stability.

Features & Design:

Four-Point Triangulated Structure: Links the rearmost subframe mounting locations to both rear strut towers for superior load distribution. Enhanced Stability: Reduces lateral and longitudinal RACP flex during acceleration, braking, and cornering. Improved Torque Transfer: Minimizes downward flex of the RACP, ensuring efficient power delivery for enhanced driveability. High-Performance Durability: Heavy-duty steel tube construction ensures lasting support during spirited driving, track use, and for vehicles with increased power output. Blue Powdercoat Finish: Offers fantastic corrosion resistance, protection from scuffs and scratches, and a stylish appearance that is sure to complement your performance-centric E46. Underside Reinforcement Compatibility: Designed to work seamlessly alongside our underside RACP reinforcement plates (TDR4675412, T#91). Kit Includes:

Sometimes choosing the correct shift kit proves difficult when you dual-purpose your favorite vehicle, we understand this well. The early days for any race enthusiast usually begins with a car that is needed to daily drive and setup to get out on the track. What becomes difficult is properly modifying that car to feel comfortable in both situations which is why we took this view on our new short shift line. This upgraded lever is a quick swap option to replace the standard shift lever that come with our kits so you can keep your hands closer to the wheel while shifting at high speeds. Designed from anodized aluminum this lever looks great in any interior for the daily driver who simply prefers the taller lever look and feel.

NOTE THAT THESE ARE DESIGNED TO WORK WITH TURNER MOTORSPORT SHORT SHIFTERS ONLY - We wanted to give you the option to buy one separately, in case you changed your mind after buying our short shifter.

Features:

Compatible with stock shift boot fits nicely into the machined groove at the bottom of the lever to maintain a clean look in the interior.
Machined from 6061-T6 aluminum and type II anodized for exceptional durability and corrosion resistance.
Available in either black or clear anodize to match your vehicle’s interior.
Rally shift knob is machined from black delrin.
Unlike aluminum, delrin will not hold heat so on those hot days you won’t have to worry about burning your hand on a knob that’s been baking in the sun.
Shift knob is threaded onto the end of the shift lever utilizing a standard ⅜-16 thread to allow for easy removal and attachment of your favorite beer tap or other accessory.
“Quick Change” height adjustable upper shift lever design allows for quick swapping between optional “OE” style and “Rally Style” upper shift levers.
22mm adjustment range to fine tune shifter throw and feel.

One of the tricks for getting your BMW to handle better is to add negative camber to the front wheels. This will put more of the tire's width in contact with the ground during cornering. With more rubber there is more grip. BMWs typically have less camber in the front to create understeer. But if you're running a stock setup on the track or autocross you are giving up speed and time as the front tires run out of grip sooner than they should.

These E46 fixed camber plates are designed from knowledge gained from our highly successful racing campaigns with the E46 in the Speed World Challenge series. These plates are offset for the best camber and caster combination for racing purposes when using the stock-diameter sized springs. Camber increases to between -2.5° to -3.0°, depending on each individual car. While ride height is increased by 1/4", the benefit of these plates far outweighs the minor ride height increase. The rate of camber change is virtually unaffected throughout the range of suspension travel, reducing the need for other geometry correction. Material has also been added to increase surface contact area therefore reducing the strut tower deformation and increasing the strength of the strut towers. Fixed mount camber plates are legal in many racing and autocross classes. These are the perfect camber solution when adjustable plates are not allowed in your class. These are a simple bolt on part for all E46 except the xi and M3 models.
