Nice job. Always nice to have alternatives.
I have the EBay kit. I believe that the spare that comes with it is the largest diameter that will fit in the wheel well - it fits snugly.
btw, the spacer I have is only 1.75" thick, so you can probably shave 3/4" off yours and be a little safer. Not sure if it would still fit over the roller skate weights though ( I replaced mine with Hawk ceramics so not an issue). You could try it on your 2nd one if you wanted...
And yeah, the factory compressor is so small, I just threw mine in the trunk as well. It'll come in handy if I just have a tire running low, but I won't use the sealer.
