Are you talking about the brake caliper on the wrong side?
The brake caliper on the wrong side to me falls into the category of "near enough is good enough" because its something I'm personally never going to notice. You guys a free to be all up set about it if you want. But once I start racing I'm never going to notice the brake caliper is on the wrong side. Heck, maybe the car has enough space that in real life you could mount the caliper on either side anyway
I can understand if you're the sort of person who likes staring at replays or photomode you might want the car models to be perfect. However I'm the sort of person who likes to race, the only time I'll watch a replay is if I did some awesome move that I want to see again, then I'll just fast forward to that point, watch it, then delete the replay and start the next race
Even during a race I use the cockpit view, so anything on the exterior I wont even notice at all, though I like to have my virtual gauges done nicely
