PM @APEX Wheels when you are ready down the road. He will gladly assist. Also, keep an eye out for Apex group buys. They are posted ocassionally.I do a bit of everything, typically not HPDE anymore though. I'll be doing SCCA time trials this weekend and autocross next weekend. But yeah this wheel/tire package is essentially a test'n'tune setup as the general track season is coming to a close (Winter is coming...). I just wanted to quickly get off the stock 235/55/17 all-seasons. I highly doubt I'm going to get anything much wider than I have now, I think my 9.5" wide wheels should be sufficiently wide, but if I get Apex wheels I may go 18x10. The Gridlife class I'll be competing in has a maximum tire width of 285, and anything wider than that would be somewhat pointless anyway, as they'd become harder to warm up, they'd be heavier, and I'd start to run into fitment issues as well. Eventually I'll get a custom aero package be forced to move up in classes, and thus be able to take advantage of a wider tire if I want. That's not in the works yet though. Before next season, I'll likely get some sets of Falken RT660's as I've found them to be my favorite for putting down fast laps. Also, thanks for the offer to help me get this stuff - if you or anyone has a contact at Apex or Falken, please hook me up!
Here's the S550 fitment guide. I'm sure you already looked at though....

Per @Bill Pemberton "I have mentioned a couple of times that when using TireRack to punch in Ext. #4362 for Luke Pavlik, as he is not just a Tire Specialist, he is a long term track rat and therefore he stays up on the different brands more than most. I have known him over 23 years and I always get good info on what tire may be seeing compounding changes or what works better for one's particular needs ( i.e. autocross, HPDE, Endurance, W2W, etc.)."
I don't know if there is a discount anymore but please mention TMO. Some of the proceeds go to TMO to help keep the website open.
