Painted brake calipers (black), discovered that the car has had two new rear calipers fitted at some point as they were far less dirty/corroded than the others, fairly pleased as it means I'm not going to have to touch these for longer.
Removed the OEM front strut brace (seeing as it does nothing but add weight, indeed not even the MX5 mk3 race cars bother having one, not to mention it will also block the top mount fitting/damper adjustment knob that comes with the suspension I eventually want to put on the car)
Checked oil and other fluid (the car did an impromptu 5 laps of Donington circuit on Saturday morning, me as passenger and driven by a guy who builds MX5 race cars and also drives them in various race series...the car held up perfectly well, but just wanted to check all was well)
Adjusted AEM intake pipe slightly to remove some of the tension in the hose joiner.
Scratched my head over a problem that has disappeared all by itself - the heater fan had started to make a clicking noise as though something was caught in it, a leaf or similar I expect, as the MX5 has no filter for the cabin air so can take in small debris easily. It drove me mad all day yesterday. But start the car today and its fine, quiet as per normal. The heater motor is easily removable thankfully, but I decided not to fiddle unless the problem comes back.
