Zac, your new 19" rims look very similar to the ones I am looking at now - very nice indeed. Have you had any problems with them rubbing on the rear arches? There are definitely more rims out there if you have jap spec brakes, but because I have the UK spec ones, it's a pain in the a*se.
Service:
I wasn't impressed by the guy on the phone at Wheelmania - he basically said we don't have anything for a Supra. Also, I drove all the way to ELITE in Rainham Essex and their service was beyond utter shite. The guy was on the phone to his mate while serving me!!! Then one bloke was gonna show me a 19" rim against my car and he tutted when his manager asked him to take the rim to my car!
ANyways, have found some nice 19" Kahn 2 piece rims, so watch this space guys.
