Actually Zac, buy a Pinny cup race car and join the guys in the Pinny Cup! Kathryn can race and you can be the team mechanic.
I only say this because I reckon she has bigger cahonas than you.
Other option:
Buy race spec R33 from Japan.
Bring it here.
Fail compliance.
Steal Mikes R33.
Use that for compliance.
Put mikes build plate on race R33.
Profit.
