The Z is allowed a lot of upgrades in the GS class.... Being the smallest NA engine.
We are also the lightest car...which helps big time when the tracks get hot.
Doran Racing really began this project after our first race at Barber after we got crushed by a Mustang in turn 1 of the race.
Engine wise : we have removed all the oem wiring and electronics and run the Grand am spec Bosch Motorsport ecu.
We run our own intake and are allowed a full exhaust system. Grand am has approved camshafts as well and a dry sump system.
Suspension wise we are still working on it to make it even better.....always
