GT300 cars are much more regulated than their GT500 counterparts, and much more closely resemble road-going versions. Chassis clips and realignments are not allowed (except the latter in the case of front-wheel drive cars), which results in a much more affordable racing experience for privateers. Canards are not allowed in GT300, even if they came on the road-going car. While engine outputs and modifications are at a lower level than the GT500 cars, the GT300 cars still post competitive times and races are relatively tight when combined with GT500 traffic

fixed tyre grip
fixed fuel tank volume and car dimensions
FFMULT force
