Every part out there,
traced back to its brand.

A full-range tuner covering turbos, intercoolers, coilovers and exhausts. Whatever the headline car of the moment is — GT-R, GR Yaris — HKS will have a product for it.

The name most associated with forged wheels. VOLK RACING, gram LIGHTS, HOMURA and VERSUS are kept as separate lines covering everything from competition use to the street. The TE37 is one of the most recognisable shapes in the Japanese aftermarket.

Synonymous with mesh design. From the forged RI-D and SUPER-RS through to the standard RE-L2. Has a supply record in F1 and SUPER GT.

Supplies wheels as original equipment to carmakers and competes in motorsport up to F1. The mainstay is PerformanceLine, cast using the MAT process to keep weight down without pushing the price up.

Nissan's works arm. Runs from catalogue parts through to menu items that include the work itself, such as the Sports Resetting carried out at a dealer.

Known for made-to-order two-piece and three-piece wheels where rim width and offset can be specified in millimetre steps. Strong in dress-up oriented lines such as MEISTER, EMOTION and SCHWERT.

Japan's largest power tool maker, with more revenue coming from overseas than at home. Runs 18V (LXT) and 40Vmax (XGT) as two parallel systems, and the batteries do not cross between generations. Bare-tool part numbers and kit part numbers that include battery, charger and case are listed separately — the single easiest thing to get wrong when buying.

Japan's largest maker of hand tools for vehicle servicing, and an original equipment supplier to carmakers. The upper brand Nepros — mirror finish and a high-tooth-count ratchet — is treated as a class of its own, and the Digi-Ratche digital torque wrench is also theirs.

Formerly Hitachi Koki. Characterised by the Multi Volt battery, which covers both 18V and 36V from one pack with the tool deciding which voltage to draw. A Multi Volt pack will also run an 18V tool.

Formerly Maeda Metal Industries. Ranges widely from large impact sockets to general service tools, and is also known for shear wrenches used in structural steelwork. The tool sets are practically composed.

The world's largest automotive parts supplier, which also makes power tools. The professional blue line and the DIY green line (Home & Garden) are completely separate. The hammer drill and the SDS-plus standard itself both originated at Bosch.

Built almost entirely around sockets, and strong in thin-wall and compact designs. Z-EAL is the upper series, with the play in the drive taken out so you can gain swing in a tight engine bay.
