Wow, I’ve never seen someone get so bent outta shape for someone else trying to offer some advice. And Steve is correct, if your a noob to most ANY road course, prepare to have a instructor in your car. Not trying to talk down to you, just telling you how it is. The cage will probably be fine, but the passenger seat won’t be. Reason being is a rule most all tracks carry about all safety equipment being equal. As a example taken from beaverun’s website.
Novice and intermediate drivers (Groups 1 and 2) must have a vehicle equipped with a passenger seat and seat belt(s) for an instructor which are equivalent to that which is installed for the driver.
I think your build has been clean as hell for a Honda, but for the sake of it get another race seat & bar padding for the other side.
