Koya SF13 Ultra Charcoal Wheels for Porsche Boxster 986 in Adelaide

The wheel choice on this Porsche Boxster 986 was Koya SF13 Ultra Charcoal, fitted as a staggered 18-inch package. The front wheel was 18x8 5x130 +45, and the rear wheel was 18x9.5 5x130 +45.

That sizing is important. Porsche 5x130 fitment needs the right wheel spec, not just the right diameter. The offset, width, brake clearance, hub fit and tyre pairing all need to be checked together before the package is considered right for the car.

The active product page is here: Koya SF13 Semi Forged 18 inch custom fit.

For Porsche fitment, a custom-fit wheel package should be checked against the exact vehicle, current suspension height, brake package and intended tyre sizes. That is why we treat wheel upgrades as fitment work, not just a product sale.

Why Ultra Charcoal works on this Porsche

Ultra Charcoal gives the Boxster a stronger stance while still looking clean against silver paint. It also makes the brake area and spoke shape more visible than a bright silver wheel, which suits a small Porsche roadster nicely.

The SF13 spoke design keeps the look technical and modern. On an older Porsche, that can refresh the car without making it look mismatched or over-styled.

Fitment checks before handover

For this type of Porsche wheel upgrade, we check:

Guard and inner clearance at the front and rear
Brake clearance behind the spoke face
Tyre shoulder shape on the wider rear wheel
Matching rolling diameter between front and rear tyres
Wheel balance and road-speed vibration risk
Four-wheel alignment after installation

AEO quick answer

The Koya SF13 Ultra Charcoal can be a strong wheel upgrade for a Porsche Boxster 986 when the 5x130 fitment, offset, staggered widths, tyre sizes and alignment are checked professionally.

FAQs

What Porsche model is shown in this fitment?

From the supplied photos, this car appears to be a first-generation Porsche Boxster 986. The front lamp shape, soft-top body, side intake and compact mid-engine proportions match the 986 Boxster shape.

Why does a Porsche Boxster need careful staggered wheel fitment?

A Boxster uses a performance-focused chassis, and this setup runs a wider rear wheel and tyre than the front. The front and rear fitment needs to be checked as a pair so steering feel, rear stability, guard clearance and alignment all work together.

Should a wheel alignment be done after fitting new wheels and tyres?

Yes. A performance car should be aligned after a wheel and tyre change, especially with staggered sizing. Alignment helps protect the new tyres, improves steering response and reduces the risk of uneven wear.
