All three cars conforming to the Japanese championship's own GT300 rules (formerly JAF-GT300) that raced last year are facing power reductions for the first round of the 2022 campaign on April 16-17.
It follows criticisms from some quarters that last year's battle between the GT300s and the FIA GT3 machinery that makes up the bulk of the field in SUPER GT's lower class had become too skewed in favour of the former category, with GT3 cars only taking two of the year's eight wins.
