@ topgeardog .There is a GTL mod out there but i can't find it anymore. I'll check to see if i have mine on backup, if i do i'll PM you a DL link. Now as for GTR2 the closest mod RD offers is the FIA 2008 GT series. PT Sims and WSGT. Those are the three i know of.
I have both mods, but I think OP might have EVO as well and just asked in the RACE forum.....I also thought that the recent exp's may have rendered them inoperable but mine still work.
They won't work online. GTL mod won't work with other mods as it's not excactly legal and the Model ID's are not regognised as "reserved" in the modding community. Use at your own risk.
PS: SimRacingManager is a tool to switch between different mods quickly. You still need to close the game while switching but it's much easier with it, use search to find it.. It's here in RD
Luckily Retro pack covers the oldies, not all of them of course but gives the chance to switch off from high-end racing machines back to basics. It's also very well modeled.
