its 1017kgs iirc not 1110kgs. bin the rear bits, aircon, all the airbags+controls for them. light weight seats up front (as you already have) and carbon bonnet etc and i rekon 900kgs is achievable mate.
then your car is same weight as say a saxo vts/106 GTI (the cars people seem to always compare a micra to lol) with more torque, watch them disappear lol
