Mugen was founded in March 1973 by Soichiro Honda’s eldest son, because Honda Motor did not employ family. There has never been a capital relationship between the two companies. In April 2004 the business transferred to M-TEC, and the brand continued unbroken.
Subaru Vivio Wheel Fitment Guide: 4×100 and +45 on Everything, Including the RX-R
Every Vivio grade runs 4×100 at +45. Only the diameter changes, 12 inch on the base cars and 13 on the 4WD and RX grades. The factory rims are 4J wide, and the hub bore is not published anywhere.
Nissan March / Micra Wheel Fitment Guide (K10 to K13): One Bolt Pattern, Forty Years
4×100 on every March generation, K10 through K13, with no changeover anywhere. Bore is confirmed at 60 mm from the K12 and unpublished before that. Factory sizes from the Japanese tables, plus the Super Turbo question.
Mazda Capella / 626 Wheel Fitment Guide: The Four-Lug Era Ended Earlier Than You Think
Every Capella in the Japanese factory tables is 5×114.3, from 1989 to 2002. There is no 1997 changeover, there is no GE-chassis Capella, and the hub bore is not published anywhere. Here is what is actually confirmed.
Isuzu Bighorn / Trooper Wheel Fitment Guide: 6×139.7 Confirmed, Hub Bore Not Published
The Japanese factory tables confirm 6×139.7 on every Bighorn grade they carry, and give no hub bore at all. Coverage stops in 1992. Here is exactly what is verified, what is missing, and how to measure the rest yourself.
Mitsubishi Delica Star Wagon Wheel Fitment Guide: 2WD and 4WD Are Not the Same Hub
Every 2WD Delica is 5×114.3 with a 67 mm bore. Every 4WD is 6×139.7. That split holds across the Star Wagon and the Space Gear, and it is the only thing you really need to get right before buying.
Mitsubishi Pajero / Montero Wheel Fitment Guide: The Bore Changed, the Bolt Pattern Never Did
The full-size Pajero stayed 6×139.7 from the V2x to the V90. What actually changed was the hub bore, from 107 mm to 67 mm at the 1999 redesign. Plus why Pajero Mini and iO wheels have five studs, not six.
Nissan Skyline V37 and Infiniti Q50 Wheel Fitment Guide
The V37 Skyline and the Infiniti Q50 are the same car. 5 × 114.3 on a 66 mm bore across all 116 rows, square front and rear — and Toyota’s 60 mm wheels will not physically go on.
Mugen Wheels: The GP, the TT, and Why They Are Not All 5×114.3
The GP is forged and metal-spun, with a claimed 2.4 kg saved against the 17-inch OE wheel. The TT is cast, and Mugen credits RAYS with making its centre cap. And the range includes 4×100 and 5×120 fitments — so check the pattern for the size, not the model name.
Toyota Hilux Surf / 4Runner Wheel Fitment Guide (130 / 185): 6×139.7, 106 mm, and Offsets You Did Not Expect
The Japanese factory tables give 6×139.7 and a 106 mm bore across the 130 and 185 series, with factory offsets from +8 to +30. Wide body versus narrow body is the trap, and negative-offset truck wheels are a trade, not an upgrade.
