battery switch is easy to do also. you can place it right under the fender or like a buddy of mine had. He had his switch on a magnetic strip so when he got to the track he could place it on the trunk and after the track he could place back inside the trunk.

 

depends on how big time he is getting though. Here in NC you can autox all you want in amateur circuit without any worries to things like that. Once you start getting into big road race events then you need to worry about tough tech inspections.
