CHEVROLET C7 CORVETTE STINGRAY / Z51 FITMENT

The narrow-body C7 Stingray and Z51 use the 5x120.65 bolt pattern — the classic GM imperial pattern. This is NOT the same as 5x120 used by BMWs and the C8 Corvette. The narrow-body fenders require significantly higher offsets than the Z06/Grand Sport widebody. Getting the sizing wrong will result in wheels poking past the fender line or dangerously rubbing bodywork. The C7 Stingray's naturally aspirated LT1 V8 produces 455–460 hp and responds beautifully to unsprung weight reduction — forged wheels are the single most impactful upgrade you can make.

Quick Reference
Bolt Pattern: 5x120.65 (Imperial) | Center Bore: 70.3mm | Hub Type: Conical Seat | Lug Torque: 135 Nm (100 ft-lb)
Warning: C7 Stingray offsets are VERY different from C7 Z06/GS. Do not use widebody specs on the narrow body — the wheels will poke past the fenders.

19"/20" Staggered — OEM+ Street

The factory C7 Stingray runs a 19/20 stagger with very high offsets to keep the wheels tucked inside the narrow-body fenders. Maintaining these proportions is essential for a clean, no-modification fitment.

01

19/20" OEM+ Stagger

A clean, slightly aggressive fitment that fills the narrow-body fenders without modifications.

Recommended Front: 19x8.5 ET56
Recommended Rear: 20x10 ET60
Street Tires: 245/35R19 Front, 285/30R20 Rear
Performance Tires: 255/35R19 Front, 295/30R20 Rear

Why this setup: Yes, ET56/ET60 looks extreme on paper — but the narrow-body C7's fenders are significantly narrower than the Z06/GS widebody. These high offsets are engineered to keep the wheel face within the fender line. Our two-piece forged construction maximizes concavity within these offset constraints, so the wheel still has visible depth and character rather than looking flat. The 285/295mm rear tire provides excellent traction for the LT1's 460 hp while maintaining proper clearance. Forged wheels save 6–8 lbs per corner versus the heavy factory cast options — on a front-engine/rear-transaxle car, that weight reduction is immediately felt in the steering.

18"/19" Staggered — Comfort & Touring

For owners who prioritize ride quality and daily drivability, stepping down a diameter provides more sidewall for pothole protection and a significantly more comfortable ride on imperfect roads.

02

18/19" Comfort Stagger

Better ride quality with more sidewall — ideal for touring and daily driving.

Recommended Front: 18x8.5 ET56
Recommended Rear: 19x10 ET58
Tires: 245/40R18 Front, 285/35R19 Rear

Why this setup: The extra sidewall dramatically improves ride comfort on rough roads. The 40-series front and 35-series rear provide a noticeable upgrade in road isolation without sacrificing the C7's excellent chassis dynamics. The 18" front clears the Z51 brakes easily. For owners who daily their C7 and value comfort alongside performance, this is the ideal compromise.
