Wow ! That is quite some comprehensive record keeping. Well done.
Considering your overall route driving (city a lot and a little track work too) it is pretty good which points to a very healthy engine and brakes that are not dragging. Excellent result really. And thanks for sharing.
Plenty of us only record fuel consumption figures on long distance highway running and that is OK. for identifying if something is not correct and needing attention. (A brake slider pin seized, brake dragging, restriction in air inlet, closed loop operation faulty, O2. Sensor). Makes you appreciate the litres flowing through that little fuel filter ?
Your car is always very well presented. Congratulations. Lot of work to achieve that.
I recently rode in a turbo 86 with good quality coilovers and was impressed with ride quality.
Was not impressed with the after market ECU.tune. Absolute rubbish. Ruined a very nice car.
Yes back seat is only for handbags but nice modern car for very reasonable money. I suspect there may be oil surge difficulties with sticky tyres on track. Turbo was limited to seven PSI.so not spectacular but a big improvement.
