Mazda Racing Prototype

The whole prototype is originally taken from a base RX-7 (SA22), everything was converted except for the roof which was partially untouched. This racing prototype was largely based on Mazda's own 787b but I wanted to make mine more unique. I would imagine this machine would use a similar engine like pretty much every Mazda's group C cars in the 90s; 4-rotor powered. Mid-engine, rear-wheel, ideally ~900kg.
