Rfactorcentral might make you pay for downloads THEY host, but you can always find the mods linked free as long as you're logged in.
It's just that most of them are on sites like megaupload, rapidshare, etc. So they aren't the fastest/best download methods.
As for me - I've reinstalled VHR and I'm tinkering with that while SCES is on a break. Race2Play seems to host a number of open races with that (and other mods/games) so I'm thinking about trying to find some time to run one or two of those. If not, public racing it is.
