Overview
Chevrolet Corvette C6 Grand Sport/Z06/ZR1 Widebody Wheel Performance
Widebody C6 Corvettes (Grand Sport, Z06, ZR1) are a common sight at track days, but most available wheel options are either too narrow or not up to the task of prolonged track use. Plus, 9.5” wide front wheels aren’t going to cut it with all the grip available from the platform. If you want to extract even more performance from your car, a lightweight chassis specific set of wider wheels and tires will make a world of difference. We created forged wheels such as the Apex VS-5RS, SM-10RS, and EC-7RS along with flow formed wheels such as the SM-10 to increase performance. Find out what fitment is best for your application in our Chevrolet C6 Corvette Widebody Wheel & Tire Fitment Guide.
A Brief History of the 2005-2013 Corvette
Our selection of C6 Corvette wheels are ready to bolt on to your Grand Sport, Z06, or ZR1 to improve performance and give it a custom appearance. America’s longest running sports car, the C6 Corvette was all new in 2005. A much needed interior and exterior update saw the wheelbase grow slightly, but overall length dropped by a few inches. The resulting proportions created a timeless body style, particularly on the widebody models, and more livable interior. These cars are capable of fitting extremely wide wheels and tires under the bodywork, a dream for track rats.
There is a lot to like about each model of widebody Corvettes, but perhaps the single biggest talking point for the C6 generation is the lump of American V8 goodness that powers the Z06. Born from the C5.R race program and refined for street use, the LS7 is a 7.0L monster shoved into a 3,000lb aluminum framed Corvette. It officially makes 505 horsepower and 470 lb/ft of torque, but any Corvette enthusiast knows how effortlessly these motors continue to make more and more power with basic modifications. Go to any track day and chances are you’ll find a 600 hp Z06 thumping away.
What Makes it a Good Track Car
With big power and huge fenders, what more could you ask for? The ZR1 is one of our all time personal favorite cars here at Apex. The Corvette on steroids as most journalists refer to it, the ZR1 combines everything GM engineers had up their sleeve into one insane package. It’s rightfully intimidating at the limit, but oh so rewarding at the same time. Let’s be honest, all widebody Corvettes make great track cars, but the ZR1 is the cream of the crop in this interbrand sports car showdown. Regardless of the model, fitting your Corvette C6 Grand Sport, Z06, or ZR1 with a set of Apex wheels is an easy way to ensure lasting track performance. Car and Driver got their hands on a ZR1 shortly after it launched and put it through its paces: First Drive: 2009 Chevrolet Corvette ZR1.
SM-10 Specifications

The Flow Form Advantage
Flow forming enables us to create high performance wheels without the price premium of forging. It improves the mechanical properties and grain structure of the barrel, increasing its strength and stiffness, which allows us to use less material and reduce weight. Thanks to our superior engineering, our flow formed wheels have a higher load rating than some competitors' forged wheels.
"I" Beam Spokes
One of the most prominent features of the SM-10 is its advanced "I" beam spoke machining. Any excess material that doesn’t add strength is carved out from the sides of the spokes using a precision CNC ball cutter. This process is often deemed cost-prohibitive by others, but for performance without compromise we believe it's essential.
Bigger, Tougher Inner Lip
The inner lip is the most vulnerable part of a wheel because it has no spokes for support. Our Flow Formed Evolution line adds more material to this high-impact area as an extra layer of protection against track berms, potholes, and whatever else the road may throw at you.
Maximizing Concavity
We use the deepest concave face profiles we can for every application after factoring in critical clearances such as brake calipers. The SM-10 utilizes 3 unique profiles to make this possible, with the deepest concave face delivering reduced weight and a stunningly aggressive appearance.
Big Brake Clearance
Big brakes often require bigger, heavier, more expensive wheels, which aren’t ideal in a performance environment. The SM-10 is one of our many wheels which solve this problem. Through comprehensive laser scanning and endless rounds of test-fitting, we’ve created 18” wheels to clear huge brakes that typically require 19” wheels from other manufacturers.
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
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.
32mm
Socket Diameter Clearance
Finishing Touches
The SM-10 is finished using a multi-stage liquid paint over a powder coated base coat. This coating process leaves lug holes, center bores and mounting pads untouched, which ensures proper fit and torque values.
JWL and Beyond
All Apex Flow Formed wheels meet or meaningfully exceed JWL load rating requirements. Some manufacturers don't meet the minimum requirements, yet still claim to be compliant. Always compare load ratings to ensure you aren’t sacrificing critical strength for a slightly lighter wheel.
True VIA
The VIA is an independent wheel testing and auditing agency similar to TÜV. Many companies falsely claim their wheels have been certified, and even use the VIA stamp without permission. Our Flow Formed wheels have been certified, and we provide the registration numbers for every wheel. Protect yourself. Demand registration numbers from manufacturers.
Additional features
Hub Centric
All SM-10 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.
TPMS
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.
Accessories
REAL DRIVERS NEED REAL PERFORMANCE.
Not all claims of performance are backed up by facts—and it's a big problem. Don't get sold fashion when you want function.
