How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
Coupes and performance platforms are where rotational mass shows up fastest — in acceleration, in braking, and in how quickly the chassis changes direction. Forging lets us build to the same strength spec as the factory wheel at a meaningfully lower rotational weight, which is where the performance gain actually comes from, not just the visual one.
The Mercedes-Benz CL 600 runs a 5x112 bolt pattern, 66.6mm center bore, and a F: 18x8.5J wheel from the factory. Our Flush Fitment reference is F 19x9.0J ET32 / R 19x10.0J ET38, which tucks the tire under the fender lip on a stock-height Mercedes-Benz CL 600. Our Maximum Aggressive reference is F 20x9.5J ET28 / R 20x10.5J ET32 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Mercedes-Benz CL 600 OE Wheel Specs
The 2007 Mercedes-Benz CL 600 (Luxury Coupe) uses a 5x112 bolt pattern with a 66.6mm center bore. Factory wheels are F: 18x8.5J R: 18x9.5J.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
Flush Fitment
For a flush look with minimal rubbing, F 19x9.0J ET32 / R 19x10.0J ET38 is the recommended starting point on a stock or mildly lowered Mercedes-Benz CL 600.
Maximum Aggressive Fitment
F 20x9.5J ET28 / R 20x10.5J ET32 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 18x8.5J ET43 → ~6.44″ F backspacing, R 18x9.5J ET43 → ~6.94″ R backspacing
- Flush: F 19x9.0J ET32 → ~6.26″ F backspacing, R 19x10.0J ET38 → ~7″ R backspacing
- Max: F 20x9.5J ET28 → ~6.35″ F backspacing, R 20x10.5J ET32 → ~7.01″ R backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Mercedes-Benz spec, or want a wheel built to a custom offset for your Mercedes-Benz CL 600? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.5, ball-seat lug bolt.
Factory Torque Spec: 130 Nm (96 ft-lb). Sedan/coupe platforms (E-Class, CLS, SL and similar) generally use the shorter 27mm bolt at this spec.
TPMS: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
