Upgraded Infiniti G37x – Supercharged, Enhanced Suspension & More!

March 31, 2014

Every so often we get a car come through the performance shop that is BIG news here at STILLEN and that happened just a few weeks ago with an Infiniti G37x. It all started a few months ago when one of our performance specialists took a call from a potential customer about a supercharger for a G37x. Over the course of a few months, the performance specialist worked with the customer making suggestions and answering questions until the customer was completely confident in his purchase. By this time, this car had transformed from a very nice G37x into many employees’ dream car.

The Infiniti G37x Wish List

This customer is a professional mountain bike racer, who also manufactures mountain bike and motorcycle performance parts. He wanted to make sure that he could modify a G37x to handle and perform as close to a GT-R as possible. To achieve his dream, he was looking to combine GT-R performance with the luxury and practicality of a sedan. Therefore, speed, handling and braking were of utmost importance to him. This car needed to be able to perform and handle the way everyone dreams a sports car will handle, but also be reliable so that the customer could drive on a variety of services with confidence. That meant that he was looking to upgrade the car’s power, suspension, braking and also had to make sure he had all of the other performance upgrades necessary to ensure the other aspects of the car were ready for the modifications that were being made.

Performance Upgrades

Parts: STILLEN 407730 Supercharger System, STILLEN 400338 STD Crank Pulley

Since additional horsepower was what had originally drawn the customer to STILLEN, we wanted to make sure we got him set up with the perfect blower for his car.  We recommended the STILLEN Supercharger for Infiniti G37, which comes in a polished or satin finish. This customer elected for the satin finish. While we haven’t dyno tested this customer’s car, this blower has previously been tested during development to output over 500 horsepower.

Cooling Kits

Parts: STILLEN 400740 Transmission Cooler, STILLEN 400632 Gold Oil Cooler

While power is important, so is longevity. Since this was also one of the customer’s concerns, we recommended he add a STILLEN transmission cooler and STILLEN oil cooler to the car. The transmission cooler will help preserve the car and help with power during hill climbs. The oil cooler will help keep the oil at the right temperature to make the supercharger last.

Coilover Shocks

Infiniti G37x with Aftermarket Coilover Shocks

Part: BC Racing BCRV-08U BR Serues  Coilover Shocks*

Since this customer’s vehicle is all wheel drive (AWD), our shock selection was admittedly slim. That being said, we found a solid option in the BC Racing coilover shocks. With their swift spring upgrade, it allowed the customer to get a higher quality shock with a more consistent spring rate. These coilover shocks also feature less coils per spring rate, which allow for a larger spoke and better travel.

*Note: These coilover shocks are not available online. Please call 866-250-5542 for more information.

Sway Bar

Part: STILLEN 304375 Adjustable Sway Bar Kit

Being an experienced driver that wants to enjoy a thrill when he drives, this customer was looking for a bit more oversteer than the stock sway bar could provide. With that in mind, we recommended that the stock sway bar be replaced with a STILLEN adjustable sway bar for G37X. This sway bar is made from high strength aircraft grade steel and is specially designed to reduce body roll and improve cornering.

Grounding Kit

Part: STILLEN 606358R Grounding Kit

With all of the upgrades being made to the car, we wanted to make sure that the electrical components were as optimized as possible and the customer agreed. To do this the sales representative recommended a grounding kit be added to the vehicle.  By adding this feature, it will allow the electrical system to work better, allowing the customer to enjoy all the performance benefits of the upgrades he had made.

Cat-Back Exhaust

Part: STILLEN 504377 Cat-Back Exhaust

The STILLEN cat-back exhaust was added for performance gains and sound improvement. Like our other STILLEN exhausts, it features a mandrel bent 304 stainless steel construction and boasts the trademark STILLEN sound that is mild while cruising, but becomes more aggressive as you accelerate.

Big Brake Kit

Parts: AP AP5700R-X Front Brake System, AP AP3752R-X Rear Brake System

When your car packs as much power as this Infiniti G37, it’s important to make sure that it has the necessary stopping power to safely slow the car down. In this case, stock brakes just weren’t going to cut it. That’s why we recommended the cross drilled and slotted AP Racing Brake Kit, which are known for being the top big brake kit manufacturer in the industry.


G37x Aftermarket Wheels

G37x Aftermarket Wheels

Parts: TSW 1985NUR455114S76 Nurburgring Wheel, TSW 1995NUR415114S76 Nurburgring Wheel*

To complete the makeover, we suggested the customer go with a set of TSW wheels.  This was because the customer’s existing wheels would not fit the big break kit that was installed and because he wanted a sportier look with better functionality. Additionally, these wheels have a rotary forged design, which maintains strength and durability, while being light weight.

*Note: These wheels are not available online. Please call 866-250-5542 for more information.

The Results

After the dust settled from all the upgrades were made, the customer was extremely happy with the power and performance he’s now getting from the car. As you can imagine, his car has plenty of power and torque to meet his goal of turning his G37 into a four-door GT-R. He’s also loved the suspension adjustments that were made with the sway bar and coilover shocks – it’s handling wonderfully for him. Plus, he gets to enjoy the stealth factor when street driving. Other drivers have no idea how fast his car can go until he chooses to leave them in the dust!

STILLEN 2013 Infiniti G37 Cold Air Intake

Just announced… STILLEN cold air intakes for Nissan and Infiniti vehicles have been CARB approved through 2014! For nearly 20 years, STILLEN has worked with the California Air Resources Board (CARB) to develop products that are compliant with OE standards of total vehicle integration and performance.

We are equally proud to announce year range extensions for the 2014 370Z , Maxima and more. For a full list of vehicle applications, please see below.

STILLEN was the first company to prove that a cold air intake on the VQ37 engine could actually make power and is still recognized as the leading cold air intake with the highly sought after Generation 3 long tube cold air intakes for the 370Z, G37 and Q60.   It took 6 months of in-house R&D and testing and 56 different variations of prototype intake systems but it was all worth it and the end result was the leading cold air intake for the VQ37 equipped vehicles.

Nissan Titan Air Intake

STILLEN Air Intake for Nissan Titan

When it came time to manufacturing air intake systems for vehicles like the Altima, Maxima, Titan, Frontier, etc. STILLEN leaned on its vast experience in manufacturing high performance parts for NISSAN/INFINITI vehicles.  On the Nissan Altima and Maxima applications STILLEN is the only manufacturer of high performance intakes that incorporates a poly-urethane ducted air intake path leading fresh air from behind the factory grille directly into the air intake filter.  Included in many of these kits is STILLEN’s unique velocity ring which increases the velocity of the air as it is drawn into the engine thus producing more power!

Note: The California Air Resources Board (CARB) is a division of the California state government and is widely recognized for having the most stringent emissions control regulations in the United States. Therefore, each of the 50 states recognizes its standards as the emissions standard for all performance parts. Each performance part that achieves CARB legality is considered 50-state legal.

STILLEN Brake Cooling Kit for Nissan 370Z Review- Featured in MotoIQ!

March 21, 2014

Here at STILLEN, we’re pretty proud of the products we make. We know firsthand how much time and effort goes into sourcing the correct materials, developing the perfect design and testing the prototypes all so that we are 100% confident that the aftermarket parts our customers are putting into their cars are the best they possibly could be. As proud as we are of the parts we make, we are even more proud when a third party recognizes a STILLEN part for its quality. Needless to say, the office was abuzz this week when we found out the STILLEN brake cooling kit for the Nissan 370Z was featured in a MotoIQ Project 370Z article!

MotoIQ Reivew: Nissan 370z with STILLEN Brake Cooling Kit

Nissan 370z with STILLEN Brake Cooling Kit

Project 370Z Article Summary

As the article mentions, the goal of Project 370Z is to get some track time with their 370Z. As improvements to the car have led to improved lap times, they have also led to more stress on the brakes. With this in mind, the team decided it was time to upgrade with the brake cooling kit. With that decision made, it was time to actually install the kit and test it. By this time, most of the STILLEN team was on the edge of their seat wanting to hear how our in-house testing was comparing to MotoIQ’s third party testing. Checkout the quote below to see how our brake cooling kit fared:

“With the brake ducts covered, the right front caliper temperature peaked at 272 degrees Fahrenheit, and the rotor at 529 degrees Fahrenheit. The Left front caliper reached 259 degrees, with the rotor at 550 degrees. Once the ducts were opened, both the left and right side caliper dropped 44 degrees. The right front rotor dropped 156 degrees, and the left front rotor dropped a whopping 216 degrees! This is a significant reduction and spot on with STILLEN’s in house testing at the same track. We were truly impressed with the numbers. Also the brake feel and control stayed more consistent throughout the session with the ducts functioning. Any 370 that sees a decent amount of track time should look into purchasing this kit, it’s a cost effective way to give yourself a higher temperature threshold for your brake system and will also prolong the life of the ware items such as pads, rotors, piston seals, and brake fluid.” – Clint Boisdeau, MotoIQ
