I want to run some hill climbs and track days but I have a 10" Lexan spoiler on the back and I think that could be dangerous for the higher speeds. I will compete in SSP class on the hill climbs so i can't run a wing or i would be bumped up to SSM class. What height spoiler should I run? I am thinking maybe replace with a 4" high lexan piece with shorter brace rods and angle more backward. Still too much or not enough? I was thinking something would be better than nothing. I have run up to 90mph straight line with current spoiler but would not want to find out what it would do in a 100+ mph turn. Any ideas?
