Looks great! What specifically are you talking about in regards to front height? You mean the front end? looks like it's sitting pretty good right now. Have you tried it like this yet?

It looks ok, with that front spoiler not sure if you would be able to go much lower. How much travel do you have in the front end?

5" should be plenty of front travel, and I would not worry about making the car sit really low at your current ET level. As the car gets faster you may want to lower it overall to reduce the instant center, but right now I think you have a good starting point.

That would depend on what the car needs. The lower hole will likely hit the tire harder, upper less hard at launch. When you put the spring in the upper hole you'll lower the car and change the center of gravity, less violent, less pitch rotation, etc. At this point in time with the car's ET you probably want them in the lower hole.
