On the street you are going to be hating life. I ran mine at that ride height the last time I was at ZDAYZ. I was on Toyo 295 30 18 square. My camber was -3.3 front and -2.2 rear. The handling was spot on. Turn in was quick and she was nimble. The down side is there are some sharp turns with quick rises and I would bottom out on them. When got home I had two rivets left on my Zspeed undertray and there was a small hole was forming on the undertray. Conversely getting in an out of parking areas and gas stations were a pain. If she is 80% track car go for it. I am looking at 26 up front and 26.5 rear.

Oh this is the exact camber setting I have and she is 99% for track except driving back and forth to the track. Was trying to see if raising it higher (to your suggestion 26”) will benefit the handling performance on the track. Also need to figure out the suspension travel issue if any.

About 2" drop is maximum for limiting issues. If you don't have a splitter then a 1 to 1.5" drop is plenty. With a splitter that is 3" plus beyond the front bumper you want to get as low as possible to maximize downforce. There is a reason that pro racing has ride height requirements.

You never want to go so low that you scrape. When you scrape, you unload the tires and suspension.
