Turner Motorsport E9X M3 Project Cars




Turner M3 Project Car #1 -- 2008 E90 M3 Alpine White Sedan


On the strength of winning 5 championships in the last 5 years, Turner Motorsport began development on the E90 and E92 platform in late 2007. After many succesful years campaigning the E46 and E46 M3 chassis in both the Speed World Challenge and Grand Am Cup race series (and the E36 chassis before that), work began on the future Turner Motorsport race and street car programs.



Naturally, we were first in line to acquire one of the first of the latest generation V8 M3s, selecting a white E90 chassis M3 sedan.

Why a sedan and not a coupe?
We've always thought of the M3 as a "touring car", probably stemming from the glory days of Touring Car racing, when E36 sedans ruled a mixed field of assorted production cars, many of which were 4 door sedans. Starting around that point, the sedans have seemed to possess a certain extra charm, reminiscent of the throw-back Touring Car days, with an extra street car "cool factor". If that isn't a good enough explanation, we also have reason to believe this latest 4 door M3 has better aerodynamics than the coupe, due to the rear window configuration.

Having an E90 M3 here on hand means we have instant access at all times to develop our own new products, as well as the ability to test fit newly released offerings from our trusted vendors. Not only does this mean a more rapid delivery of new products to the market, but it means a higher degree of knowledge as well as better product quality control. Why would you want to buy parts for your "new" M3 from a company that doesn't own one to develop and test their products on? This is all just part of our commitment to our customers.

Since this was our first E9X M3 Project Car the goal was to identify the shortcomings in the performance potential of the "new" M3. There are always compromises in the final car spec so that it appeals to a wider audience. Even with Motorsport in mind the car BMW releases to the public cannot be too racy for fear of turning off too many buyers. But our core customers want and expect more race and track engineering, even when the cars are used as daily transportation.

Right away we knew the M3 V8 was going to be a truly great M car and a worthy descendant of the original E30 M3. Only time will tell if the M3 with a V8 will hold its place near the top of the list but we think BMW did a fantastic job with this car. The S65 V8 is a gem, the brakes and chassis are well engineered, and BMW wisely offered three body styles for this car, ensuring there is an M3 to suit every one's needs. Stay tuned to our site and this page as we fine tune an already great package.

    Turner M3 Project Car #2 -- 2011 E92 M3 Frozen Grey Coupe

    Continuing our passion for all things BMW, Turner Motorsport was the first customer in the US to receive one of thirty 2011 E92 M3s finished in "Frozen Grey" flat paint. This option was made available through BMW's Individual Program and included the Competition Package, Premium Package, Technology Package, the M-DCT transmission, and special Fox Red and black interior colors and trim. It was one of the first times BMW promoted an Individual model in the US and served as a test for offering more Individual models and options in the years to come (the E9X M3 had many special models and trim packages).

    What are our plans for this car? We wanted to take this car to new heights in the E92 M3 tuning realm. The matte grey paint was a promising starting point for a very unique build. Along with our other Project Cars we also wanted to develop new products and evaluate others. You'll have to stay tuned to this site where we hope to have all kinds of unique Frozen Grey upgrades as well as other tuning and enhancements for this special model.

    Turner M3 Project Car #3 -- 2013 E92 M3 Lime Rock Park Edition

    BMW's long and enormously successful history at Lime Rock Park is what inspired BMW North America to introduce this special model. BMW's modern-day racing program has had an envious record at the Connecticut racetrack - since 1997 a BMW product has either won, finished on the podium, or scored the pole positon for every headlining event at Lime Rock. And Turner Motorsport has been right there carrying the torch with 7 wins in a twelve year span, including 4 in a row from 2004-2007. And with Lime Rock being our own home track - Will Turner grew up just down the road - of course we had to have one of these special cars.

    Our LRP M3 was ordered with minimal options to make it extra special. We were inspired by the E36 M3 Lightweights that were so popular among BMW Club enthusiasts in the mid-1990s. Our car has no iDrive, cloth manual seats, manual transmission, and no sunroof. Like all Lime Rock Editions it came with the Competition Package, M Performance Inconel exhaust, M Performance carbon fiber trim, and Fire Orange paint. The simplicity of this car is refreshing and its focus is clear.

    What are our plans for this car? There are multiple routes we can take with this car. With its Fire Orange paint and black trim it's tempting to create a M3 GTS replica with the stroker motor and build a killer track car. On the other hand this is a limited production model and it may be in the car's best interest to keep it factory-spec and focus our upgrades on simple bolt-on parts that make a difference.

    H&R Sport Plus Spring Set for E9X M3
    This spring set will help firm up the stock suspension as well as reduce body roll. They will also make a noticeable visual improvement to the M3s stance, reducing the perceived fender gap of the stock ride height by .75" front, and 0.25" rear compared with the stock competition package suspension. The same ride height as the standard H&R Sport springs but with a stiffer spring rate geared even more towards track performance. These springs combined with the H&R 27mm sway bar below are the perfect combination for a dual purpose street and track car.

    H&R Front Sway Bar E92 M3
    The H&R for the E9X M3 is the best anti-roll bar option for the E9X M3. The H&R swaybar is over 52% stiffer than the factory E90/E92 M3 bar and even over 42% stiffer than the E93 M3 sway bar upgrade. There are several reasons for this - the stock sway bars are hollow (for lighter weight) and will twist more than the solid H&R bar. Also, the E93 M3 bar is often called a 28mm bar but it actually tapers down in the center to 24mm which greatly reduces its effectiveness. So if you're looking for a serious sway bar upgrade, the H&R is clearly the way to go.

    Custom 4.10 Differential for E9X M3
    One of the "best bang for the buck ” upgrades for your E9X M3 is a shorter differential gear. Making the ratio change increases torque delivery to the ground by allowing the car to operate in the ideal power band more of the time. We feel that changing the gearing one of the top 3 things to do to make your M3 faster and perform better on the track.

    The 6 speed M3 comes with a 3.85 gear and we choose to install a 4.10 gear ratio to increase acceleration. We also raised the rev limit from 8300 to 8600 to compensate for the shorter gear.

    Inconel BMW Performance Exhaust for M3
    With the racetrack and the street in mind, this new exhaust system is crafted from an extremely heat-resistant and lightweight chrome-nickel alloy called Inconel ®. This flow optimized exhaust system reduces exhaust backpressure and allows the M3 ’s 414 horsepower V8 engine to produce an even more powerful sound. Inconel's unique qualities allowed engineers to reduce the thickness of the tubing from 1.5mm to 0.8mm. This resulted in a weight reduction of approximately 40%, or about 20 lbs. when compared to the stock exhaust system.

    E92 M3 Turner Motorsport Test Pipes (Cat Delete)
    We have done extensive dyno testing on several E9X M3s with just the Test Pipes as well as developing a custom tuned Stage 2 Race software specifically for the cat-delete. Time after time, our dyno has shown HUGE INCREASES IN POWER with this setup. This mod is so well known that copies of the Turner Test Pipes are showing up. When these Test Pipes are combined with our Race software, they gross 40hp @ 8000 rpm and 32 lb/ft @ 3000rpm. Freeing up this power is essential for a track car.

    Turner Motorsport Race Software for E9X M3
    This special Race software is designed to work with a Test Pipe, or other front exhaust section that eliminates the primary catalytic converters. On our own M3 project vehicles, this combination netted 40hp and 32ft-lbs of torque* - a massive transformation to an already impressive output. Our Race software makes use of the same features of our street legal Stage 1 software - altering ignition timing, fuel mixture tables, and VANOS operation with the added benefit of using a racing exhaust without the front or back catalytic converters. We also chose to raise the rev limit to work with our 4.10 ring and pinion to put our Lime Rock M3 in the power band in every gear.

The Power Pulley reduces rotational mass and safely under drives your belt driven auxiliaries for reduced parasitic power loss. The end result: More power to your M3's rear wheels! Designed to give the best performance benefit with no sacrifices or compromises to your BMW's reliability. These have been tested on hundreds of cars before public release and there are simply NO DOWNSIDES to this upgrade. The combination of these power pulleys with Turner software and Test Pipes is perfect for any track or street M3.

    APEX EC-7 18x9.5/10.5" Satin Black Wheel Set
    APEX light alloy wheels are the next evolution in flow-forged wheel technology for BMWs. Flow-forming is a semi-forging process that produces a wheel typically stronger than a traditional cast wheel yet is still light weight. The wheels are around 10lbs lighter per wheel than a comparable factory wheel! That's reduced unsprung weight that improves all aspects of performance.

    H&R Sport Springs for E90/E92 M3
    H&R Sport and Sport Plus springs will help firm up what many consider to be a fairly "soft" stock suspension (at least for a BMW "M" car). They will also make a subtle and noticeable visual improvement to the E92 M3's stance, reducing the perceived fender gap of the stock ride height by 1.0" front, and 0.6" rear over the stock suspension.

    E9X M3 Bilstein Sport Strut/Shock Package
    Bilstein has released a set of non-EDC struts and shocks to go along with a set of sport springs such as our H&R sport spring set, or Eibach, etc. Bilstein's Sport shocks are designed for lowered suspensions where additional travel is needed to keep from bottoming out. Bilstein's use digressive valving which is stiff on slow wheel movements (highway, autocross) and soft on fast movements (bumps), giving a very balanced and comfortable ride. These shocks replace the factory EDC shocks or work without EDC.

    E9X M3 Coil Over Suspensions
    Street Coil Over Suspensions are like a traditional shock and spring package but better! The obvious advantage is in adjusting the ride height in the front and rear through the adjustable spring perch. This allows you to achieve the perfect stance and ride height for your needs. But coil overs are also a shock and spring that are engineered to work together. Ride comfort and performance are noticeably improved with coil overs when compared to a off-the-shelf shock and spring combo.

    Street Coil Overs that we recommend:
  • Bilstein PSS10
  • KW Variant
  • H&R Street Performance

  • Contact us if you would like guidance on what suspension will work best for your needs.

    E9X M3 Sway Bar Upgrades
    Sway bars (anti-roll bars) are used to fine-tune the handling of the car. Larger bars will reduce body roll and change suspension behavior to reduce understeer. We typically recommend a swaybar upgrade after doing shocks and springs but you can use bigger bars with stock suspension too. A lot of our customers install the larger E93 convertible front sway bar to improve steering response and handling feel with no other changes required.

    E9X M3 Monoball Front Control Arm Bushings
    These bushings for the front control arms use an aluminum and Nylon encased bearing to deliver superior precision steering feel and response. Unlike stock rubber or urethane bushings, these bearings have no deflection and will not twist or bind up under load. The bearing is super smooth and precise. They are a direct replacement for the stock bushing that wears out pretty quickly.

    E9X M3 Solid Rear Subframe Mounts
    Solid aluminum subframe mounts replace the stock rubber mounts that flex too much under load. Rubber mounts allow the subframe to move - and consequently the rest of the rear suspension moves too. Too much flex will change the alignment and give you inconsistent handling or just an insecure feeling when cornering. The rubber deflection gets worse as the rubber bushing wears. We use these solid mounts on all E9X M3 and other cars, even daily-driven cars, and BMW installed solid mounts on the F8X M3/M4 from the factory.

    APEX Light Alloy Wheels
    APEX Wheels are the perfect complement to your BMW. Their designs are inspired by classic motorsport wheels of the past but with a fresh approach to manufacturing and customer support. APEX uses the flow-forming manufacturing that produces a strong but light weight wheel. As well as being pleasing to the eye these are very strong and functional wheels that are at home on the street as well as the racetrack. The design is based on classic motorsport themes that blend with BMW styling and appearance. These wheels look right at home on many BMW models. Multiple color and profile options allow you to set just the right look and stance for your car.

    Click here for more info on E9X M3 Apex wheels.

    For the E9X M3 we have preferred sizes and offsets in staggered and non-staggered wheel sets. Non-staggered sets are typically used for track wheels so you can run the same size tire in the front and rear. The stock wheels are staggered with a wider wheel in the back for more traction. Ideally, we want to give more grip in the front with a wider tire without sacrificing traction in the rear. Our wheel sets vary in width from 8.5" to 11.0" in 18" and 19" diameters. For a really aggressive fitment, like on our Lime Rock M3, we use a 9.5" ET22 front wheel with a 255/40 tire and a 10.5" ET27 rear wheel with a 295/35 tire.

    Forgeline GZ3R TrackSport Wheel Package
    We wasted no time getting our M3s on the track, where we could stretch their (long) legs and get some test time in on our enhancements. After our street tires were spent, it was time to find the ideal Track Wheel & Tire package -- and we did just that. The end result is a lightweight and extremely strong forged package that can be rotated (something you can't do with stock wheels) and allows the use of 275 width Hoosiers or other R compound tires. Our friends at Forgeline helped us find the ideal wheel and offset, so that we could maximize the tire size (front and rear), and still maintain clearance (without rubbing or a "funny looking" stance). This package includes 4 genuine Forgeline race wheels -- the same you'll find on our Grand Am Cup KONI Challenge cars. So you can be sure these are the finest wheels for the extreme conditions of driving the E9X M3 on track. This package is 24 lbs lighter than a set of stock wheels!

    Forgeline wheels are custom made to order. While we gave you the size and offset specs you can design your own finishes. These wheels are made to order based on your design. Choose from one of our preset finishes or come up with your own! In addition to polishing, matte colors, or gloss paint, Forgeline can also do factory paint colors.

    Front & Rear: 18x10" 5x120mm - use with a 275/35-18 tire
