You can perhaps make a second driver/player with it's own PLR with the line (in GraphicOptions) wheels visible in car (or something like that) set to 1 instead of 0.Eats a bit of fps but perhaps not on your rig.
I have changed the line in my "show wheels in cockpit" line in my .plr, and it doesn't seem to affect other cars
I think you can change stuff in the .plr, but this is the install I use for leaque and I didn't wanna do that. Any ideas or am I doing a new install?
