Well real cars chassis get damaged when you race them, especialy road cars if your taking them to the ring every weekend sooner or later your going to end up with a cracked and or warped chassis, unusual uneven tire wear can be a symptom of something very wrong with the chassis in real life at lest . I can tell any car i have driven if it is good or bad, just by driving it a bit. Heck even in cars i have never driven i can have a pretty fair guess at how they should behave by their drive layout, weight, bhp, turbo or natural, etc. FTG and bobs have known issues at nurburg track, do not recall them having problems at monza however but my bob raced it in the rain. And i had a decent tune that took the car habit of just spinning out on whim and made it slide rather than snap kill you. Which is the tendency i found in the bone stock car a tendency that really annoyed the hell out of me. But that one section of nurburg he loved to just drive the car off the road, good thing he had taken first in every race and had a good lead going at nurburg so i think he still managed first there, despite him running the car off the road not once but twice and think even sun it off one of the times. BUt naw i think chassis is fine, just saying it is not covered in the instruction book and i have never heard kaz or anyone at pd really get into the who whys and whats of it. BUt you would not really have any clue in real life either until the thing just went, you might have nagging unexplanied problems with the car but to have the chassis inspected is usually the last thing anyone ever thinks of. I mean this one guy had his chassis fractured from driving, and only thing odd with the car is one of this tires would go bald and just kept going bald to the point he was having to have his tires replaced everytime he went to the track, well i do not recall what the final straw was but the chassis under the car was cracked in half when they finally got around to checking that after they checked just about everything else with the axles the suspension the brakes the computers. SO it not all that easy in real life to figure out oh yea i trashed my chassis, lucky for that guy they found it before he did a few laps more or else his discovering it might have been his car shearing in half while driving down he road.
