An Ultra-Concave Split Five-Spoke Built on a Flow-Formed Barrel
The Kansei K15W-189012+22 is an 18x9 Astro in Gloss White, drilled 5x114.3 with a +22 mm offset. Kansei builds the Astro with its FORMLITE process on A356-T6 aluminium, and the design itself is protected under US design patent D1024892.
Key Features
- FORMLITE construction, Kansei's process for a stronger and lighter barrel than a conventional cast wheel.
- A356-T6 aluminium alloy throughout.
- Mounting-pad pocketing and a reinforced inner rim lip, both weight and strength measures at the load-bearing areas.
- Maximum-in-class brake clearance, which matters on an 18-inch wheel over a big brake setup.
- TPMS compatible and compatible with Kansei's gel caps.
- Ultra-concave split five-spoke face protected by US design patent D1024892.
- Gloss White finish across the full face and barrel.

This is a wheel, so it carries no vehicle fitment tag. Selection is by bolt pattern, offset, bore and clearance. The 73.10 mm bore and 1,550 lb load rating are published on the size table for the identical 18x9 +22 casting in Gloss Gunmetal; the Gloss White page lists the same size range without repeating the table.

About Kansei
The Astro is Kansei's ultra-concave split five-spoke, and it is built on the company's FORMLITE flow-formed barrel rather than a straight gravity cast. Flow forming stretches and compresses the barrel after casting, which is how the design keeps a deep concave face without the weight penalty. The wheel's face design is registered as a US design patent.

FAQ
What size, offset and finish is this Astro?18x9 inches on a 5x114.3 bolt pattern with +22 mm offset and a 73.1 mm centre bore, finished in Gloss White.
Is the Astro forged?No. It uses Kansei's FORMLITE flow-forming process on an A356-T6 cast blank, which sits between gravity cast and forged in both weight and cost.
Does it work with TPMS sensors?Yes, Kansei lists the Astro as TPMS compatible.
What is the centre bore?73.10 mm, published on the size table for the identical casting in Gloss Gunmetal.
How much load will one wheel carry?1,550 lb per the same published size table.
Is the design protected?Yes, the split five-spoke face carries US design patent D1024892.
Will it clear a big brake kit?Kansei advertises maximum-in-class brake clearance, but caliper clearance still needs checking against the specific kit before mounting tyres.
Are valve stems supplied?No. Valve stems are not included and need to be added at tyre fitting.
How many wheels does this listing cover?One. The Astro is sold per wheel.
Installation Instructions
- Check the 5x114.3 pattern, +22 mm offset and 73.10 mm bore against the vehicle before mounting tyres.
- Order hub-centric rings if the vehicle hub is smaller than 73.10 mm.
- Test fit a bare wheel and check clearance at the caliper, the strut or damper body, and the inner fender at full lock and full bump.
- Have tyres mounted on equipment set up for a gloss painted finish, and ask the shop to protect the face and lip during mounting.
- Fit valve stems, and transfer or fit TPMS sensors at the same time since the wheel supports them.
- Torque the lug hardware in a star pattern to the vehicle manufacturer's specification.
- Re-torque after roughly 50 to 100 miles and inspect the face for any mounting damage.
