Running a staggered 18x8 front / 17x10 rear configuration, this CTS-V Coupe delivers the balance drag racers need: front-end weight control, rear-tire traction, and brake clearance that works with factory and upgraded V-series components.


Front Wheel & Tire Specs — CTS-V Coupe: Lightweight Control.

Wheel: WELD RT-S S70
Finish: Polished
Size: 18x8
Bolt Pattern: 5x120

This 18x8 front setup is ideal for Cadillac CTS-V Coupe and Sedan drag racing, offering reduced rotating mass while maintaining proper brake clearance for the V-series platform. The 225/50R18 tire keeps rolling diameter street-friendly while helping weight transfer on launch.


WELD S70 RT-S Rear Setup: Traction Where It Matters.

Wheel: WELD RT-S S70
Finish: Polished
Size: 17x10
Bolt Pattern: 5x120
Backspacing: 7.2 in. (High Pad)
Spacer: 1/4"

The 17x10 rear S70 is a go-to size for CTS-V drag racers. With a mild 1/4" spacer, this setup allows the aggressive 305/45R17 tire to sit correctly under the rear fenders while delivering the traction needed for hard launches.

This configuration is commonly used on CTS-V Coupe and CTS-V Sedan drag builds, especially those running upgraded suspension, power adders, or drag-oriented tire compounds.


Why the WELD RT-S S70 Works So Well on the CTS-V Platform?

The WELD RT-S S70 is a forged drag wheel engineered specifically for high-power vehicles that demand strength without excess weight.

Key advantages for CTS-V applications include:

• Forged aluminum construction for high torque loads
• Reduced rotational mass for quicker acceleration
• Proper pad heights for GM V-series brake clearance
• Proven durability for repeated drag launches
• Available in multiple sizes to support staggered setups

This makes the S70 a top choice not only for CTS-V models, but also for Camaro SS/ZL1, ATS-V, CTS-V Sedan, and other GM performance platforms.


CTS-V Coupe Fitment Notes & Takeaways.

Based on this setup, here’s what CTS-V owners should know:

17x10 rear wheels are a proven drag size for traction
305-width tires fit well with proper offset and spacing
18x8 front wheels balance brake clearance and weight
• Minor spacers may be required depending on suspension and alignment
• Proper pad height selection is critical on V-series cars

As always, suspension mods, ride height, and tire choice can influence final fitment.


Proven WELD RT-S Fitments Across Cadillac & GM Performance Platforms.

While this Cadillac CTS-V Coupe is equipped with WELD RT-S S70 drag wheels, the RT-S platform as a whole is widely used across multiple high-horsepower GM performance vehicles that share similar brake packages, hub specs, and drag-focused suspension geometry.

These WELD Racing S70 RT-S wheels are frequently used on the following GM performance platforms:

Cadillac CTS-V Sedan (2009–2014)
Cadillac CTS-V Coupe (2011–2014)
Chevrolet Camaro SS & ZL1 (2010–2015)
Chevrolet Camaro SS & ZL1 (2016–2024)
Chevrolet SS Sedan (2014–2016)

Thanks to compatible bolt patterns, brake packages, and rear-wheel-drive chassis layouts, many of these platforms can share similar RT-S wheel sizes, offsets, and backspacing, making the RT-S lineup a versatile solution for GM drag racing builds.

As always, final fitment depends on brake upgrades, suspension setup, tire selection, and intended use — which is why confirming specs before ordering is always recommended.
