What you choose on this page
-
Colour — select it in the variant picker above. Matte Black (MBL), Trans Gray Polish (TGP) and Brushed (BRU) share the same widths and inset ranges; the price differs by colour.
-
Width — select it in the variant picker above. Width and colour set the price; width sets the shipping weight. Prices are per wheel.
-
Disk type and order inset — tell us these at order (in the order notes or by message). WORK builds this wheel to an order inset: for each width and disk type you may specify any inset inside the range printed in the table below, and WORK makes the rim depth to suit. We confirm the exact inset, rim depth and air valve with WORK before the order is placed.
-
Quantity — pricing is per wheel, so select 4 for a full set, or mix widths for a staggered (different front/rear) setup by adding each width to your cart separately.
Order inset ranges on this page (21 inch STEP RIM)
Figures are WORK's printed order-inset ranges in mm, highest inset first; the rim depth in brackets is the depth WORK builds at each end of the range. Any inset inside a range can be ordered — combinations outside these ranges cannot be built in this configuration. The letter is WORK's disk code and the figure in the column heading is that disk's hub height clearance.
Why is WORK ZEAST STX listed on more than one product page?
WORK builds the ZEAST STX in more than one diameter, and each combination has its own widths, disk types, inset ranges and specifications, so we list each diameter + rim type as its own product page, with all colours available on it. This page is only for 21 inch STEP RIM.
Looking for a different size? ZEAST STX is also listed in 20 inch STEP RIM. Search "WORK ZEAST STX" in our store to see all available listings. If you cannot find the configuration you need, contact us: we can quote any current ZEAST STX specification directly from the factory lineup.
Notes
Price is for one wheel — select the correct quantity for a full set. ZEAST STX is built to order by WORK in Japan; contact us to confirm the current lead time before ordering. Each wheel includes one black centre cap and one air valve per wheel (air valve V41C). The buff-anodised rim is standard. Hub height clearance on this page: A-Disk (MIDDLE CONCAVE · STANDARD) 48 mm, H-Disk (MIDDLE CONCAVE · DEEP RIM) 38 mm, O-Disk (DEEP CONCAVE · STANDARD) 47 mm, W-Disk (DEEP CONCAVE · DEEP RIM) 33 mm. WORK ZEAST STX 21 inch REVERSE clears JWL-P840KG (passenger car standard). WORK lists ZEAST STX as TPMS-compatible.
Special P.C.D. (range in the table above) is a WORK custom order with a surcharge from ¥11,000 per wheel (approx. US$65) — the yen figure is WORK's, "from" means it is a floor, and the US dollar figure is an approximate conversion confirmed on quotation. WORK asks customers to check which nuts or bolts to use, so please contact us before ordering a special P.C.D. WORK optional items for ZEAST STX, at WORK's catalogue prices per piece (converted on quotation): silver or red centre cap at no extra charge; gold piercing bolts from ¥11,000; black chrome piercing bolts from ¥5,500; black air valve from ¥550. Standard piercing bolts are chrome. WORK notes that the colour can look different between concave shapes, and that Trans Gray Polish has thinner-looking areas by the nature of the paint. Semi-order colours are available through WORK's Custom Order Plan on request. WORK notes that some specifications cannot be produced depending on manufacturing conditions, and that some specifications may take longer to deliver. Please message us before ordering if you would like fitment advice, or if you need a configuration that is not shown here.
