Since the diameter is probably fixed due to the wheel/wheel well configuration (no retractable tundas), it seems one might look into a second set of calipers and/or multiple disks (similar to the arrangement on many larger jets). There would of course be a weight penalty, a wear/longevity degradation of the rotors/disks, and added heat generation you may need to consider. I believe the Formula One guys use carbon based disks which might be an option. I have dual calipers on my TR182 and it is very easy to make flat spots on the tires without even knowing it. It skids so easily without adverse yaw that is hard to tell when braking too hard. Sometimes I can tell if one is skipping. The first time it happened it made a flat spot which rendered the tire unairworthy. I pay more attention these days. --0-543550945-1173808625=:74112 Content-Type: text/html; charset=iso-8859-1 Content-Transfer-Encoding: 8bit > If you are working under the assumption of dry pavement, perhaps enhanced brakes are an option.  Since the diameter is probably fixed due to the wheel/wheel well configuration (no retractable tundas), it seems one might look into a second set of calipers and/or multiple disks (similar to the arrangement on many larger jets).  There would of course be a weight penalty, a wear/longevity degradation of the rotors/disks, and added heat generation you may need to consider.  I believe the Formula One guys use carbon based disks which might be an option.
