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
On a track-focused car the factory already spent the unsprung-weight budget carefully, so the aftermarket brief is narrow: same footprint, less mass, more barrel clearance for the brake package. Chasing poke on a car like this usually costs lap time before it buys looks.
We publish the factory specification for the Porsche 911 GT3 below. We have not yet been able to verify aftermarket flush or maximum-aggressive offsets for this exact variant against a source we trust, so we are not listing any - an invented offset is worse than no offset when a wheel has to clear a caliper.
Porsche 911 GT3 OE Wheel Specs
The 2010 Porsche 911 GT3 (Track Sports Car) runs a Centerlock hub with a 71.6mm register. Factory wheels are F: 19x8.5J R: 19x12J.
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
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Porsche 911 GT3 (2010) we cut the centre bore to 71.6mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Aftermarket Fitment: Confirmed on Request
Published aftermarket fitment for this exact variant is still thin, so we have not committed to a flush or maximum-aggressive figure. Our engineering team is still collecting verified data for this variant. In the meantime the factory specification above is accurate and is the safe reference point for ordering.
What we do know: APEX VS-5RS centerlock 19x9J ET47 front / 19x12J ET63 rear; or Forgeline GT1/GE1 monoblock centerlock; BBS E07 centerlock - all verified 997.2 GT3 fitments (Shark Werks/APEX/Rennlist) CENTERLOCK - buy forged wheels with Porsche centerlock spline (Forgeline/APEX/BBS/HRE); do NOT use bolt-on conversion. Confirm exact offset with wheel maker.

Frequently Asked Questions
What is the center bore size on the Porsche 911 GT3?
The Porsche 911 GT3's center bore is 71.6mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
Do I need wheel spacers for my Porsche 911 GT3?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Porsche 911 GT3?
The Porsche 911 GT3 runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
