That's the problem I have too...some issues are easy enough to fix, like I can put in a 5 point harness instead of the 4 point I have now. or install a drive shaft loop
But I'm not cutting up the car to put a 5 point roll bar or a full cage for the couple times a year I may want to track it.
I re-geared the rear over the winter too, so I'll be a little slower there too. Maybe with street tires, 3.27 gears and and extra 5280ft in altitude I can loose 2.5 second and my car will pass tech
