Overview
Chevrolet Corvette C7 Grand Sport/Z06/ZR1 Widebody Wheel Performance
Widebody C7 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. Especially the factory wheels, which are incredibly prone to damage from even casual street driving. 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 C7 Corvette Widebody Wheel & Tire Fitment Guide.
A Brief History of the 2014-2019 Corvette
Our selection of C7 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 C7 Corvette was all new in 2014. While the C6 was more of a refresh of the previous generation, the C7 is all new in many ways. A new fully aluminum frame and redesigned interior meant maximum performance and improved comfort when not pushing to the limits. Factory wheels have proven to be troublesome for widebody C7 owners over the years with countless reports of cracking and other damage.
The new LT series engine featured direct injection and of course, more power! A dry sump LT1 powered the Grand Sport pumping out 460 horsepower and 465 lb/ft of torque mated to a new 7 speed Tremec TR-6070. The Z06 received an LT4, which was essentially an LT1 with a 1.7L TVS supercharged strapped to the top. And the mighty ZR1 received GM’s most powerful production engine to date, the LT5. This 6.2L V8 was force fed by a 2.65L TVS supercharger, making an eye watering 755 horsepower…on a car that comes with a warranty. Insane.
What Makes it a Good Track Car
Grand Sport has been tied to GM Racing heritage for years. As such, Grand Sport models of Corvettes are typically most geared toward track use. They aren’t the fastest or most powerful, but they brilliantly combine the best attributes available to form a complete package. MotorTrend said it best in this excerpt: The Stingray’s naturally aspirated 6.2-liter V-8 is surrounded by the Z06’s gnarly bodywork, flared fenders, meaty tires, and wide-track suspension. Think of the Grand Sport as basically equal to the track-ready Z06 in every way save for power. To check out their full review, click here: 2018 Chevrolet Corvette Grand Sport.
Adding a set of Apex Wheels to your C7 Grand Sport, Z06, or ZR1 is a great way to improve performance with stunning good looks.
SM-10 Specifications
Reproductive Harm - www.p65warnings.ca.cov SM-10 features
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.
A Wheel You Can Depend On
Accidental Damage Replacement
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.
