16" rims suck.
Only a few sizes to pick from. I ran in FSP, using Kumho 710's on slower/smaller courses or Yokohama Advans for big open fast autoX's and track days.
I now use 15" rims to lower the CG without having to slam the suspension, and there are way more options for tires.
17" probably offers more options than 16", but you probably cannot go up a rim diameter without getting classed as a modified or prepared vehicle. So only 15" or 16" rims for everything except an SVT! Make sure you study the clubs' car classification specs for allowed mods etc. Rim widths are also a big part of class rules so make sure you know before you purchase anything.
i ran a 19" wheel and tire without getting bumped out of class. the wheel means nothing.... its all about the tire.
