Kind of a late date to be asking for advice but my advice would be to either cancel until you have a chance to take at least one HPDE day with a racing club and instructor to learn how to handle your car on a road course- or take it extremely easy on the course so you don't tax your car and your driving skills.
A few laps at speed can be a blast, but without the proper set up and experience, it can also be a white knuckle experience or much worse.

Also, you will need to at least pass tech inspection and you may need two roll bars to take an instructor on the laps. If you don't have the double roll bars, you can take your daily driver for the first (or second) track day until you are cleared to drive solo, then you can drive the Cobra for future track days as long as it is without an instructor.

Have fun and be safe.
