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
With less structural stiffness from the missing roof, a convertible's suspension tuning leans more heavily on unsprung mass control. Forged construction keeps wheel weight down at the same strength rating, which is one less variable working against the Aston Martin DB7 Vantage Volante's chassis.
The Aston Martin DB7 Vantage Volante runs a 5x120.65 bolt pattern, 73.8mm center bore, and a F: 18x8.0J wheel from the factory. Our Flush Fitment reference is F 18x8.5J ET32 / R 18x9.5J ET38, which tucks the tire under the fender lip on a stock-height Aston Martin DB7 Vantage Volante. Our Maximum Aggressive reference is F 19x9.0J ET28 / R 19x9.5J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Aston Martin DB7 Vantage Volante OE Wheel Specs
The 1999 Aston Martin DB7 Vantage Volante (Luxury Convertible) uses a 5x120.65 bolt pattern with a 73.8mm center bore. Factory wheels are F: 18x8.0J R: 18x9.0J.
Why the factory spec works for most owners:
- Preserves the factory-tuned ride and steering feel
- A mainstream size for this segment, keeping tire choice wide and prices reasonable
- Leaves full clearance for the stock brakes and suspension hardware
- Keeps handling predictable and consistent in everyday conditions
Flush Fitment
For a flush look with minimal rubbing, F 18x8.5J ET32 / R 18x9.5J ET38 is the recommended starting point on a stock or mildly lowered Aston Martin DB7 Vantage Volante.
Maximum Aggressive Fitment
F 19x9.0J ET28 / R 19x9.5J ET35 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 18x8.0J ET38 → ~6″ F backspacing, R 18x9.0J ET45 → ~6.77″ R backspacing
- Flush: F 18x8.5J ET32 → ~6.01″ F backspacing, R 18x9.5J ET38 → ~6.75″ R backspacing
- Max: F 19x9.0J ET28 → ~6.1″ F backspacing, R 19x9.5J ET35 → ~6.63″ 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 Aston Martin spec, or want a wheel built to a custom offset for your Aston Martin DB7 Vantage Volante? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
