This may not apply to you at all.... but a remodel is always a great time to reorganize. People tend to sort similar things into groups (fluids, filters, tools, etc..). I always encourage them to think about the tasks they plan to perform and set up that way. A shelf for brake stuff, pads, bleeder, fluid, maybe even the 10mm wrench for the fittings is the way to go. All the oil change stuff in one spot, wheel changing stuff next to your wheel rack....including torque wrench, impact, the gloves you use, anti-seize for the bolts, etc..
Don't mean to rant, it is just a nice opportunity to set it up right.
I know what you mean, but I guess my racing years have led me down a different path. I tend to keep tool types together, fluids together, abrasives, etc. My scales and other items like that are kept to one side in their own rollable cases, as they are used less frequently than, say, a 13mm box spanner. For consummables like pads, these are kept separate in small bins labeled according to suspension, gearbox, brakes, etc. I used to use a notebook, ala Carrol Smith's practice, but an Excel spreadsheet is a planned switch, one per car, plus one for garage supplies, including nitrogen and welding gases.
I'm planning to install a media cabinet next year, so that will require storage for media types, and an anodizing run. All storage needs will be mapped out well before these are even set up and installed. I really hate clutter, and hunting about for things just wastes time.
My main problem right now is geography. The 2-car and 1-car are separated by about 25-30 feet, with the electrical service panel in the 1-car. I want to run air to both, putting the compressor in the 1-car and using RapidAir piping and tubing. I just don't know about burying the aluminum pipe to span the "gap" between the two garages.
Lots to do and to think about,
