Well, my reunion with my car isn't till summer... But I'll chime in. Z1 SP brake upgrade package, JWT clutch & flywheel, CSF radiator, Z1 red polyurethane engine bay hoses, M370 [bought another one :)], EVOR lip, twin supercharger kit.... and maybe a new exhaust if my current one doesn't do well under FI. Oh, I'm on the same boat with 265/305 RE11's, but on 20/25mm spacers.
