This has been driving me NUTS

I think you will beat him in the 1/4 mile but top end speed I don't think you would win. Forget trying to beat him around curvy roads. Stick to your guns and tell him that his car is designed to hang corners so to keep it fair you only can race him on the 1/4 mile. Keep in mind the consequences of racing on the street if you get caught... but I'm not your mother. LOL!
