I know, and I even stated as much on the previous page. I only do tuning prohibited races and I change the oil on every car I race before I take it to the track. Custom wheels, even of different sizes, are also allowed under tuning prohibited, as is use of the power limiter and brake bias adjustments.
I do remember a couple of updates ago there was a bug effecting tuning prohibited rooms. I forget the details of it, but if you had created it as a tuning-unlimited room and then after the room was open changed it to tuning-prohibited then it wouldn't allow any car on track (stock or otherwise). But if you created the room originally as tuning-prohibited then stock cars could enter the track. Or something like that, I may have that backwards as I never experienced it. Maybe there's still a lingering piece of this bug causing random problems?
