And for your front roll center setup why do you have the FF on the outer most hole and the FR on the middle hole? What's the idea behind this?
Also I saw you are running 4.8mm front and 5.0mm rear ride height, I've always been told the minimum ride height is 5mm as that is what the rules are. What's the reason for running 4.8?
Firstly, about the foam inserts. The last few years I've always run my car with as close to 0 or almost negative rebound in the shock in an effort to make the car more planted. The foam inserts add rebound and that wasn't something I was looking for at this race. Maybe on asphalt, but 0 rebound always feels best to me on carpet.
Second, the front roll center inserts were that way because I had added what's called arm sweep. Its like giving the front some inboard toe out, so when it dives down into the corner under braking it's more stable and easier to push.
Third, the ride height. When the ride height is tested, the procedure generally is to not set (push down) the suspension before the test. Now, if they were to explicitly say they were going to be setting the suspension, I'd run a lot higher ride height, but as long as they don't you can get away with a little bit under.
Hope this clears some things up.
