997 GT3 Wheel Performance

Porsche finally got the rear specs of the 997 GT3 wheel setup dialed in but left front width and a chunk of weight on the table. If you are looking to maximize the performance of your GT3, a lightweight chassis specific set of wheels will make a world of difference. We have options from our Forged EC-7RS and VS-5RS as well as some Flow formed SM-10 wheels depending on use case and budget. Find your perfect fitment on the Porsche 911 997 GT3 Wheel & Tire Fitment Guide.

A Brief History of the 997 GT3

What can be said about what is arguably one of the best cars to ever come from Porsche. While a set of our 997 911 GT3 wheels will improve the car by shedding ~29 lbs of rotational weight off the car, let's get into what makes this GT3 so special first. The 997 GT3 holds a special place as being the last manual transmission only GT3’s. While still being the more hardcore option for those looking to go to the track, the 997 had a few comforts built in like the standard sport seat and PCM. Power and Torque are up compared to the previous GT3, now at 409hp and 299 lb-ft and a redline of 8,400rpm. The GT3 continues to come with revised bodywork and a fixed rear wing to not only aid downforce but also improve cooling. The 997.2 GT3 was shown for the first time in 2009 at the Geneva Motor Show featuring further revised aero and an increase in displacement. Now with 3.8L to work with the car now put out 429 hp and 317 lb-ft of torque. The new bodywork doubled downforce numbers from the 997.1 and included more vents to aid cooling. This was the first time stability control came on a GT3 to assist drivers new to the rear engined platform. 997.2 was the beginning of the new norm for GT3’s where they all started coming equipped with centerlock wheels.

What makes it so good on track

Short answer, everything. The 997 GT3 is designed for the track with factory coilover suspension, larger oil coolers, transmission cooler, shorter gear ratios, lighter weight and one of the best engines to ever be fitted in a Porsche. Our 997 911 GT3 wheels are a great way to improve the performance by pulling a substantial amount of rotational mass out of the car. Depending on if you have a 5-lug 997.1 or a centerlock 997.2 we have numerous options on our Porsche 911 997 GT3 Wheel & Tire Fitment Guide.

EC-7RS Features


10K Tons of Pressure

Our new forgings weigh as much as 120 pounds before machining. To form such a thick blank we require special equipment capable of 10,000 metric tons of pressure. This extreme pressure increases the strength of the aluminum by eliminating porosity and improving the grain structure.

True Motorsport Blanks

Many companies use 3rd-party blanks intended for non-motorsport wheels which can severely limit sizes, concavity, spoke design, and critical brake clearance. We designed our very own blank profiles from scratch to give us total control over the final product.

Side-Milled Spokes

One of the most significant upgrades to the EC-7RS is the addition of wider and deeper side-milled spokes. Any excess material that doesn’t add strength is carved out using a precision CNC ball cutter. Side-milling is often deemed cost-prohibitive by others, but for true performance without compromise we believe it's essential.

A Stronger Lightweight Wheel

Our forged Sprint™ wheels are lightweight without the strength compromises found on typical lightweight wheels. First, we carved out as much material as possible, then we purposefully added one pound back to reinforce critical areas, creating a stronger inner lip and a higher load rating.² What’s the point of a lightweight wheel if it’s fragile?

Load Ratings (lbs)
JWL Load Standard 1521
Typical Forged Wheels 1521
APEX Flow Formed 1550
APEX Forged Sprint™ Line 1600

Weight Optimized

We conducted extensive Finite Element Analysis (FEA) to reinforce high-stress areas and to remove material where it didn’t improve strength. The result is a wheel that is exceptionally light without the strength compromises found on typical lightweight wheels.²

Independently Tested

We don't rely solely on computer simulations or unverifiable in-house testing. We believe independent testing is critical to protect consumers in this unregulated industry. We chose STL, an independent lab in Ohio, to test our Sprint™ wheels far above JWL standards, including increases in testing duration, impact drop height, and total load.

Tougher Inner Lip

Introducing the Sprint™ spec inner lip, with a unique channel profile that makes it even stronger than our previous designs. So even though our Sprint™ wheels are pounds lighter than comparable flow formed wheels, the inner lip is stronger.

Big Brake Clearance

From day one, APEX has been on a mission to build wheels that clear big brakes. Our new forged wheels are the product of everything we’ve developed over the past 10+ years, including an innovative high-clearance barrel design and vehicle-specific spoke profiles.

Deeper Concavity

Our new forgings were redesigned to create extra deep, concave spoke profiles. Their new shape allows us to make any profile, from flat to deep and everything in between. Each one is optimized for a specific application using 3D laser scans of factory and aftermarket brake kits.

Paintless Knurled Bead

Whether it's a day at the track or months of street driving, repeated hard braking and acceleration can make a tire slip along the bead seat and go out of balance, causing vibration. Knurled beads help, but are less effective when painted over. Our forged line features unpainted knurled beads that stay sharp and maximize grip.

Built for Impact Sockets

Track wheels need track tools. Don’t settle for wheels that require undersized tuner lugs or thin walled sockets. All APEX wheels accommodate over-sized race lugs and impact sockets to make swapping wheels lightning fast.


Socket Diameter Clearance

Laser-Engraved Specs

As track enthusiasts ourselves, we know how frustrating it is to try to locate and decipher wheel specs that have been hastily hammered into the rim or become unreadable over time. With our new Sprint™ wheels, we chose to invest a little extra and laser-engrave the specs on the barrel, in plain sight, making them easy to find and read. (You’re welcome.)

Additional Features

Hub Centric

All EC-7RS wheels are purpose built for select vehicle applications. Very few applications require centering rings.

Center Caps

All APEX wheels come with our gloss black cap included that is interchangeable with the OE cap. We also offer additional colors for select fitments.

Wheel Hardware

APEX wheels can be used with all OEM mounting hardware, proper aftermarket hardware and most wheel spacers. Wheel locks and stud conversion kits also work perfectly.


All APEX wheels accept OEM and aftermarket Tire Pressure Monitoring Sensors and standard fit valve stems. If you don’t have sensors, then select from our metal stems available in multiple finishes.

EC-7RS Warranty

A Wheel You Can Depend On

All Apex Wheels come with a lifetime structural warranty against defects in workmanship and materials, plus a 1 year finish warranty. Exchanges are fast, easy, and hassle-free.
See terms and conditions.

Accidental Damage

Curb rash or pothole damage on the street? Make an oopsie at the track? We’ve all been there. APEX is proud to offer 50% off replacement wheels, no matter the damage.
