The hand-out motor for GTC-FK will be the JK Hawk Retro. Those running GTC-Pro will be able to run any legal IRRA motor. However, this will be the last year for that. R4/10 will be all hand-out for GTC.
In addition the following tech reminder.....
When you bring your car to Tech you will need to have the body COMPLETELY REMOVED from the car so all measurements can be taken.
Also, please remember if you are "vision challenged" you will need to bring your geezer goggles to re-pin the body.
