Making a 818SR from an 818S with an 818R Koni Suspension set at 4" - Questions

I'm not sure you would want the R suspension on a street car. From the road & track article:

The phrase "ride quality" doesn't apply here any more than it does in a go-kart. Nor is there a lot of rubber between the wheels and your hands. If you really want to drive this to and from the track, pick a route without potholes, lest you arrive without your kidneys.

I think Dave mentioned somewhere that they have a much softer (and higher riding) setup for the street shocks. I'll try to find it.

I don't think there are any bars in the doors. Here you can see the bar from the frame visible inside of the door skin.
