From simple cosmetic upgrades to our massive Stage-5 Six-Piston Porsche Cayenne Big Brake Kit, the ECS MK5 GTI completely transformed. The GTI has experienced a Kafka-style metamorphosis being cocooned by an enormous list of modifications to arrive, stunning and gleaming, as it hovers above the ground before you.
ECS developed this build to create something unique; to be something contemporary yet traditional. As a show car, the MK5 catches looks and double-takes. As a driver’s car, one behind the wheel might discover a fiendish smile with every touch of the throttle or dive into a corner.
With each modification designed to fine-tune and enhance the performance of the GTI, this show stopper is more than just a pretty face.
Impossibly obvious and attention grabbing, the ECS Carbon Fiber Fender Flare Kit garnishes the corners with carbon fiber. For German performance cars, the widebody treatment is always reserved for the most extreme, race-bred applications. This performance and styling effect distinguishes the sporty model variants from the truly dexterous and radical performance cars.
The bolt-on ECS flares display exceptional fitment, and allow up to an additional 75mm of wheel and tire clearance for the use of fat rubber and a stunningly wide stance. the cavernous wheel wells, extended by the flares, encouraged our decision to develop a custom set of 3 Piece Custom Rotiform Style LVS – 11″ Wide, 19″ Diameter, completed with a Copper Face Finish.
Not quite hidden behind these stunning wheels are the massive ECS Stage 5 Six-piston Porsche Big Brake Kit, featuring the ECS 2-Piece Cross-Drilled and Slotted Rotors in the front and back. This 352mm finishing touch not only looks great behind the copper face of the wheels, but gives you the stopping power of a gravity well.
In designing the suspension, we chose a complete Slam Series Digital Combo Air Lift system with AutoPilot V2 digital air management. This Air Lift system gave us the versatility we needed to maneuver the most treacherous roads comfortably, fly through rhythm sections effortlessly, and drop to the pavement: all with the simple push of a button.
Between giant potholes, speed bumps, and uneven terrain, we constructed a 3/16″ (4.76mm) thick 5052 aluminum Street Shield Skid Plate. This skid plate is constructed and fitted to protect the exposed underbelly from a variety of impacts which can ruin an oil pan or other critical components.
Under the Hood:
There are modifications strictly for a vehicle’s curb appeal, and parts that exclusively intended for performance. Our goal was to include as many parts capable of utilitarian performance chasing and exude an aesthetic brilliance. We strove to create a part that has both proven performance gains and is aesthetically pleasing.
Our ECS Kohlefaser Luft-Technik Intake System features a carbon fiber box and polished aluminum tubes for stunning under the hood looks, and maximum power gains of +17 WHP at 5,750 RPM and +12 Lb/Ft of Torque at 5,700 RPM.
Complimenting the intake is the ECS High Flow Charge Pipe Coupler Kit that is capable of withstanding greater heat and higher boost pressure than stock. The kit does this all while achieving greater reliability, less turbulence and less restriction.
Moving down the sequence, we see the ECS 3.0″ Valved Turbo Back Exhaust System. Having a genuine appreciation for a smooth and sporty exhaust note that doesn’t drone or leave ears throbbing is something illusive. Smooth and refined is agreeably conservative, but there is a time and place for the sound of guttural anger.
With a remote key fob-controlled, vacuum operated, valve diversion, the exhaust flows at your convenience. With the valve closed, the exhaust is tuned and quieted through directionally louvered internal tubing. With the valve open, the exhaust follows an unrestricted, straight through path, and the dyno results confirm the difference. Don’t worry, though, you won’t need a chart. You’ll notice a Mr. Hyde style alter-ego emerge with a flattened throttle pedal. Bruce Banner would be proud.
Ever important to a highly modified motor is the brain controlling all of your critical systems. The factory computer was digitally altered and programmed with the aggressive APR Stage 2 Tune.
To harness all of this extra power, we have fitted the GTI with the ECS in-house designed Performance Pendulum, Engine, and Transmission Mounts. These mounts are composed of a perfected polyurethane formula to deliver smooth power transfer through the driveline to the ground, while equally present to minimize chassis feedback.
With a panoply of modifications, one could spend hours drooling over the complete parts list. While this is a dedicated show car, the performance capability is there thanks to the design of the components involved in bringing the MK5 GTI a viscous Moreauvian style genetic modification are all available through us here at ECS Tuning. Below this article you can browse the complete list of modifications and turn your own MK5 GTI into something terrifyingly gorgeous.

If you are looking for an unusual build with heart and devotion, here’s Mike’s build. Mike purchased this CL600 when it was nearly dead in 2015. He put over 850+ hours of work into it to make it what it is today. He began fixing over 40 initial problems from purchase and then later made over 40 modifications to it as well. Mike submitted his build to us in the 2016 Virtual Car Show and it was still in production. And now the World’s first rear mount turbo setup on this Model/Engine.
It all started when I went to go look for a “practical car”. Out of the corner of my eye, I saw the V12 emblem peering out from the snow pile. I asked the salesperson what was under there and he replied “A piece of junk Mercedes”. I said I want to test drive it and after 2 hours of cleaning snow off of it and out of it I got my wish and limped it around on its test drive. I knew immediately that I was going to buy this car regardless of how neglected it was. I went to get a pre-purchase inspection and found out that it had $45,000 worth of repairs needed at dealership price. So, I bought all the parts needed and did all of the repairs myself which was a great learning experience. Fast forward 2 years, 850+ hours of working on it, 70+ repairs/modifications, 1 Magazine feature (Mercedes Enthusiast), 2 broken bones, and an endless number of sleepless work nights…it was completed. The once broken and abused CL600 is now the World’s First Rear mount turbo CL600 V12 M275 Mercedes-Benz…and it loves it. As heavy of a car, as it is, the engine and heart of the car has been unchained and is running as it has always wanted to…as a supercar engine just like it is in the 1st Gen Pagani Zonda’s.
I have completed several projects on the car that either no one or only a couple of people have attempted (some of which I helped). For instance, the car originally came with a hydraulic suspension system called ABC. ABC was great unless something went wrong and that was an unfortunately common occurrence leaving you stranded. I decided to convert to coilover suspension and retrofit a non-ABC tandem steering pump and completely deleted the hydraulic system. From there I decided to install a Nitrous Express system. This was tricky, as was every project because there is NO support or DIYs for these vehicles. People are afraid to change the 24 spark plugs the car comes with, let alone what I was doing to it. After successfully completing some passes at the drag strip on nitrous, I still was not happy with the way the car’s power fell on its face after the first couple thousand RPMs. I knew a turbo upgrade was needed from the small stock twin turbos…but what could I do there was no room and heat soaking was already a serious issue.
After researching for a few months I decided that a rear mount 78MM Borg Warner turbo would be the solution, I just had to figure out how to plumb everything, supply oil, and get the engine to play nice. I contacted Eurocharged Performance for tuning advice and decided they were definitely who I would be working with. After acquiring some sponsorship opportunities from Toyo Tires, Eurocharged Performance, Glowshift Gauges, APEX PERFORMANCE TURBO SYSTEMS, and a few others locally the build got underway! With the help of a friend, I was able to remove the stock turbos without pulling the engine. From there I was able to remove all of the stock turbo parts, vacuum system, ignition system, and exhaust. I installed the SLR McLaren Mercedes-Benz upgraded 722.6 valve body springs, solenoids, and the Eurocharged TCU.
Once I was able to get the car stripped, the fabrication began! I used 2000-2002 non-turbo CL600 exhaust manifolds (inverted and flipped around to fit) to start my custom exhaust layout.
I welded all of the custom bends (which proved difficult on a V12) followed by the mid piping and to the trunk’s T4 flange. I used 2.5” piping leaving the engine and merged to 3” piping staggered in the back and heavily wrapped to keep the air hot going to the turbo. I used a TiAL 44mm wastegate paired with a GReddy electronic boost controller and a 4” single split exhaust leaving the big Borg. The turbo was mounted and welded the framing into place for the plexiglass trunk basin. Next, I designed the best oiling system I could think of for the rear mount turbo, which was a standalone oil reservoir in the trunk. This consisted of the reservoir, an oil temp sensor a feed pump from Turbowerx, a check valve, a pressure sensor, a sump pump (matching Turbowerx pump), another check valve and pressure sensor, and lastly an oil cooler all of which is the trunk. At the front of the car, the engine bay received a much better water to air cooling system and polishing since you were finally able to see the actual engine. I am hoping to hit my goal of 1000 HP this year and will be doing so after a cross country Rt66 road rally in August.
The car survived the 116-119 degree F heat of Death Valley and the Mohave Desert, but also the 11,000+ foot elevation change in Colorado. The beast enjoyed the New Mexico roads that seemed to expand endlessly into the horizon and also the sharp twisties through Oatman Arizona. In Santa Monica, California, the Nasty V12 gained the looks and photos of many passerby’s, but it also gained attention the night before racing into LA from the mountains. No matter what beating I gave the car on this trip it seemed to take it and then returned the favor with G forces. The only issues I ran into were a stone chipped windshield, a shattered fog-light (removed), and a leaking oil return line in the trunk that I had to replace in New Mexico. The emotions when I was driving home the last 2 minutes were strong. I listened to Odesza “Say My Name” and enjoyed the amazing and beautiful V12 soundtrack. Upon parking the car in my garage and sitting there letting the oil circulate a bit more before shutting it off, I realized something in my heart…I realized just how incredible these machines truly are and also how much magic / amazing memories they can bring to your life.

I was getting tired and started to look for something that had more power than my 1998 3000GT (still own/drive). Had the 3000GT for over 12 years.
After a year of searching for specific features, I spotted this C63 down in LA at Keyes European. I decided to fly down test drove it and bought it the same day and then had it shipped back to Kansas. Have had the C63 since November 2014. Just been slowly adding things onto it. Started off with wheels and tires from HRE then moved onto a tune from Eurocharged. Blacked out some trim pieces and got tint. Then removed the secondary cat and replaced it with stainless steel straights (work done by Kultured Customs). Not much more I want to do with it, maybe headers and supercharger down the road if I ever get tired of it lol. It is my daily driver.

I wanted to do simple and functional, that would break my neck every I left it. Of course, the first thing I purchased for the S4 was ST Coilovers, to get the perfect ride height. Along with the purchase of the coilovers, came the RS4 grille with Matte Aluminum surround to give the front end a more aggressive look and the Roc Euro intake to hear the supercharge wine. It didn’t take me long to get wheels! A week after purchase, the new Avant Garde M590’s in Satin Silver 19×9.5 et 40 came in to give the S4 in my opinion a simple, yet classy look. 1 year later, I wanted to make the front end more aggressive. So I purchased a Carbon Fiber DTM Lip to add to the front end. Then I wanted to make the car sound like a racecar (because racecar) and purchased a GMG World Challenge Racing Exhaust and paired that with AWE Non-Resonated downpipes. Ended up removing the center muffler and doing a custom straight pipe to the exhaust for more aggressive tone. Over the winter, I wanted to get a wheel setup that would look good for shows and purchased Avant Garde F520 3pc wheels in 20x10et 35 all around w/ Brush Copper face and 2.5″ polished step lip. Overall after I was done, I was satisfied with how the S4 turned out! Something that was simple and classy, but also looked mean and aggressive.
