Turner BMW F13 M6 Project Car

** Updated 7/13/2015 **

The BMW M6 has been considered a flagship M car since its introduction in 1983. Since that introduction, the BMW M6 has always been acclaimed throughout it's lifespan for it's somewhat aggressive lines and styling, giving rise to it's nickname the "Shark Nose". The current F13 M6, the successor of the E63 M6, is the third generation in the lineage of the M6. Between 1990 and 2004 BMW removed the M6 from their model lineup, reintroducing it with the S85 V10 engine at the Geneva Auto Show in 2005.

This latest M6 comes from a background of high performance coupes which means it has an extremely high expectation to live up to. Both the E24 and E63 M6s set the bar for performance during their time of production. The E24’s 3.5-liter inline six, a modified version of the M88 used in the legendary M1 super car, produced 282 hp and over 250 lb-ft of torque. In 2005 the E63 was introduced with the extremely high-revving, S85 5.0-liter V10, producing a whopping 500 hp and 384 lb-ft.

This latest M6 comes with the S63TU which is a twin turbo 4.4-liter V8 producing 560 hp and just over 500 ft-lbs of torque, edging out the previous E63 generation by 60 horsepower and 116 ft-lbs of torque. In addition to the added power, there is quite a bit of added weight as well; the F13 M6 is over 400 lbs heavier than its predecessor.

First Impressions:

Yes, 400 lbs is a huge amount of weight, and the newest M6 is a bit longer and wider than its predecessor. Climb in the unique cockpit of the M6 and suddenly you become part of the car. You sit low, held in by the interior which seems to wrap around you, focused on the road ahead of you through the low cut windshield. Click the gear shift over to manual mode, hit the M1 button and suddenly that 400 lbs is left somewhere on the asphalt behind you.

The Project:

At Turner we pride ourselves on being on the cutting edge of performance and technology for BMWs. We want to have a complete understanding of these new cars to continue our reputation as a leading BMW tuner. Please stay tuned for more to come on the new M6. Our goal is to take this third generation M6 and make it unique. We are going to hand pick the best possible products and accessories for this project car to learn first-hand the true potential of this latest generation of forced induction BMW power plants. Please stay tuned as we begin to modify this M6 and review the products we use.

H&R Sport Spring Install:

We installed the H&R Sport Springs on our F13 M6. H&R springs are designed to lower you vehicle to improve handling by lowering the center of gravity, thus decreasing body roll and weight transfer. They also reduce that annoying fender well gap on BMWs with stock suspension. Although the new M6 does come from the factory with a lowered ride height compared to other F12/F13 6-series it still needed to be a bit lower. We were a bit hesitant to put springs in this car because of how good the stock ride comfort and handling was, the EDC system on this car is fantastic. That being said, H&R springs are the best out there and we knew they could only improve the car. They are one of the first upgrades we perform on our project cars, from our E92 M3 and F10 M5 to our ActiveE Electric 1-series.

The Install:
The install of these springs took approximately six hours. It involves removing all four coil over (spring and strut assemblies) from the vehicle. Each coil over plugs into the EDC system which makes the removal and install of the strut assemblies a bit tricky, especially in the rear where you need to access the top of the strut from under the rear deck tray. You must remove the rear speakers and some trim pieces to access the the EDC harness and the three bolts holding the strut.

The most difficult and time-consuming part of the spring install is making sure there is ample room to remove the rear strut assemblies, without damaging the EDC harness on the strut itself or anything around it, such as the electronic emergency brake. We found the best way to do this is to disconnect the rear sway bar, remove the rear caliper with electronic emergency brake and disconnect the rear control arms. This gives plenty of room to pull out the coil over strut out of the rear wheel well. Other than that the install is relatively straightforward, the front is basically just like most other BMWs.

The H&R springs lowered the car exactly one inch in the front and one inch in the rear giving the car a great stance with a small amount of rake. We love the look of the car with the H&R sport springs, just the right amount of lowering gives the car a slightly more of an aggressive stance.

Driving Impressions:
The comfort of the ride is virtually unchanged, especially when the EDC is set to comfort mode. You begin to feel the difference when you put the car into sport, thus stiffening the dampening. The car is a bit stiffer going over certain bumps and changes in the roadway surface, but they are very minor. The body roll is significantly decreased and acceleration and braking feel better. Before you could feel the rear of the car hunch down when on wide open throttle, and you could feel the nose drop when threshold braking. Those symptoms of the stock springs seem to be minimized with these H&R springs , making the car a lot more fun to drive. The steering also feels a bit sharper in all steering modes while still tracking down the road as the stock set up did. Overall, we feel these springs are a great fit for any M6. There is very little compromise in stock ride comfort for less body roll and sharper handling. These springs are very well matched to the F13 M6. So, if you're looking for a relatively inexpensive but significant improvement in your M6s stance and handling you cannot go wrong with H&R Springs.

Turner Race Inspired Axle-Back Exhaust:

Our Race Inspired exhaust deletes the rear mufflers in the F13 M6 to allow more of the exhaust sound to be heard. We love our M6 but it's just too quiet, so we looked at ways to get more of the stock exhaust to be heard. After evaluating the stock exhaust layout it was easy to see that removing the rear mufflers would accomplish what we wanted. But cutting the mufflers off is just the beginning. We then had to develop a set of pipes and design a set of tips that fit perfectly and also looked right at home on the new M6. And these M6 muffler delete pipes are the finished product.

section: rear section (rear muffler delete)
connects to: stock section 3 pipes (ahead of mufflers and just aft of rear subframe brace)
tip style: 102mm (4.0") quad angle-cut round in polished stainless or satin black with Turner logo
material: T304 stainless steel
power gains: +14hp / +19ft-lbs
weight savings: 15lbs total

Vorsteiner Forged Wheels:

We have decided on a set of Vorsteiner VSE Forged Wheels for our F13 M6. The factory 20" M Double Spoke wheels look great, but since the M6 is one of BMW flagship model, we thought it was deserving of an equally worthy set of forged wheels. We decided on the Vorsteiner VSE-003 series wheel, finished in a matte gunmetal. We ordered the wheels in 21" diameter with 9.5" and 11.0" widths for this wheel set and have custom ordered the offsets to be aggressive on the M6. Vorsteiner's full forged series of wheels are made from the highest quality T6-6061 aluminum and have big brake kits compatibility right out of the box. The wheels are offered in three finishes among eight colors, as well as optional custom finishes, including paint matching. Now our M6 has aggressive, high-quality wheels to go along with its equally impressive appearance, upgrades and performance.

Vorsteiner Carbon Fiber Aero Splitter, Diffuser and Spoiler :

Our F13 M6 started out life as a very attractive piece of modern design and engineering. However, with the addition of 21" Vorsteiner VSE-003 series wheels, it was clear we needed to add some equally high quality carbon fiber aero pieces to compliment the mono-block forged wheels. Vorsteiner's carbon fiber front splitter, rear diffuser and rear lip spoiler give our Project M6 an even more aggressive and menacing appearence, all while adding a new level of class. Vorsteiner uses only the highest quality raw materials and manufacturing techinques to create their automotive art. Instead of hand-laid carbon fiber composites, Vorsteiner uses a autoclaved, pre-preg carbon fiber method, giving their pieces superior stiffness along with aerospace strength and durability when compared to traditional methods. The perfect additions to BMW's flagship M model.

Official Vorsteiner F13 M6 Photoshoot :

As mentioned above, our Project F13 M6 was equipped with a number of pre-preg autoclaved carbon fiber pieces and full forged monoblock wheels from Vorsteiner. These pieces included the Vorsteiner Front Carbon Fiber Spoiler, as well as the Vorsteiner Rear Carbon Fiber Diffuser. Both of these pieces enhanced the appearance of the M6 greatly. The front spoiler makes the F13 M6 extremely menacing when traveling down the road, whether it be at a stop light, or on the highway. Finishing out the Vorsteiner pieces on our M6 are the Vorsteiner Carbon Fiber Rear Deck Lid Spoiler, as well as a set of 21" Vorsteiner VSE-003 fully forged monoblock wheels, measuring 9.5" in front and 11.0" in rear.

After being covered in the highest quality carbon fiber aero pieces and forged wheels from Vorsteiner, we decided our Project F13 M6 deserved to be photographed in a manner that matched our M6's amazing personality and presence. Here's the end result. Enjoy!
