Looks like Christmas arrived a little late in that garage!
Welcome to the forum! I also chatted with you at Bruce's Christmas party. You picked a sweet spot in the seven range - not too much hp for the road and very quick for the track day fun. 13 inch wheels are perfect - I run them on my 420R and CSR - less rotational mass so you accelerate quicker and the thicker side profile improves ride comfort and (to my mind) improves handling.
My first suggestion is do an inventory of everything you have now. I guarantee you will be missing the old bolt, nut or part so its always good to identify this now, put your request in to get them so that you do not get an interruption during the build right when you have momentum going.
Looking forward to seeing this build progress!
Cheers
