Also remember that this is one of the few tracks that run on high curbs.Yes you'r right, i tryed the boxer and all went smoothly, i dont understand why mod car do crawl at the start of race and right then there is a full caution if that wasent enough.
And i heard what Marc Collins said, i agree this is a common flaw with moded cars.
Prolly cause some creators do things that interfere with the physics.
So far the mod cars I've tried have been fine but am sure that I also have some that will not be suitable for this track.
