Really, I've never been razzed about my seats once. I bet it's your buddies giving you a hard time. Can you imagine running an autocross with stock seats.
That 19/20 combo with the addition of the half height body bushings help it look lower than it is in reality. I have run mine similar height in the front and slighly higher in the back. I found when it got to low in the back, my rear yoke contacted the tunnel lightly. It wasn't something I heard. I suppose my added horsepower along with large contact patch out back combined with the soft setting I use on the street doesn't help me. I've got it where I can punch it in first gear and hook it up now with my r888's. It really squats nice. I would be on the lookout as your springs settle to make sure you don't get to low for your tunnel. Measure your ride height now so you can reference it later. You could always fabricate a bump stop on both axles if needed. The stock stuff won't work. On the front I added the 275's and the r888's seem to be more square. The first time I autocrossed them the course had 2 tight 90 degree turns. That was the only point where I had a rub and it was on the outside on both sides. Since I've added camber and raised the front a hair. I'm running my next autocross in a few weeks. I'm sure it will be fine.
I'm glad you finally posted some photos. You did a great job
