As the title implies,those of you out there who have done thousands of miles.
Edit;How far will rigidity decrease until?Will it decrease until the car is "undrivable"?

I haven't. I have a Vettle X2010 with 30K Miles on it. The engine defiantly shows wear, after a few oil changes it will drop in HP and not go back up until the engine is rebuilt but the chassis always seems the same. I think I straighten the chassis once on it and rebuilt the engine 5 times. Runs like new.
 
Honestly never been able to tell a difference. I rebuild the chasis of all my nicer cars though, cuz who wants a car with a ****ed up chasis?
 
well , i done a few miles on my r8 5.2 fully tuned and im having troubles these last races , its acutaly to wild , i mean it dosnt have grip ! i changed tyres and changed oil , done everything but still its the same :(

Try to use a less upgrades, lets say

-Weight 2
-Engine 2
- sport Ecu
-Sport Air filter
-Sport exhaust
- Sport Catalytic Converter
- fully custom transmission
- Single plate cluch
-sport flywheel
-Fully custom LSD set to 5/20/5

Tires try Sport mediums- if you can control it try racing hard but i think sports are best to drive on

Keep in mind, sometime fully upgrading cars makes them worse. Now if you were using this car with no issues and then it eventually becomes wild with no changes that could be chassis.
 
I've never noticed the effect... and then the other day I bought the Nissan #1 Pennzoil Skyline ('99? '00?) from the UCD.

Driving it around Daytona Road Course I could actually tell that the chassis was gone. It felt really... twisty! I did the chassis overhaul and it was much much better.

I have other race cars on a higher mileage that don't seem so bad so I guess the answer to the OP is this; when it needs the chassis overhaul then you'll know :D

Thanks for ur tipps !!

This is exactly what happened when I took the C8 Laviolette for a test drive right after I oil changed it.

So how'd it feel compared to normal?you noticed it by stuff like kickback through the steering or less stability?
 
After 2000miles on my chrome line Lamborghini.... Won't even go around Daytona without spinning out, the chassis is completely shot!!!

I have an LP640 more than double that mileage and the only thing i've noticed is a slight tumble in lap times by a few tenths of a second,though the G loading due to the banked track at daytona might aggravate the chassis.I'll check it out,thanks for the heads up.
 
Ive got a gt spec II test car that has about 5800 miles on it, i started noticing it was having a little understeer around 3000 miles, i went and rebuilt the chasis and it was cornering like it was new, so id say chasis goes at about 3000 miles, but im sure it varies between cars and how often yo crash into things.

I dont know why it got understeer as a non rigid chasis will usually cause the opposite i believe, but like i said, it must vary from car to car.

yeah,my guess is the chassis bends and the tyres don't load evenly or the chassis lack of rigidity makes it twist so the suspension isnt working effectively.This,unlike the tyre thread I locked,is useful:tup:
 
My ZR1 RM needed doing after 20k, it just seemed to be realy jumpy and bouncey on long corners, it felt like a new car after I did it but dam why is it so expensive to do?
 
I see...how did you notice it?More steering kickback etc?
less steering and slower body response, more weight transfer, less overall grip. The engine also needed to be rebuilt, which is another clue. Seems like PD made it so that these things wear at a same approximate rate.

Well I assume you have to take the whole car apart replace floorpans,structural supports,etc..lotta labour.

Yup,seems so,thanks for your input!
 
Ok after 13000 miles I compared my LP640 with my newly acquired LP670 and what a difference! The new car was so much more planted and nippy,more controlled with much higher grip.Part of it,but definitely not all of it is from the LP670's enhancements...So now I want to ask,will the rigidity keep decreasing to a point where the car becomes "undrivable"?
 
As a rule I rebuild the chassis every 1k miles. The only car I have noticed a degrade in performance was in my mp4 12c. I want to say I was around 1500-1700 miles on the chassis when I rebuilt, and after the rebuild the car firmed up noticeably.

The RS6 advant is wild. The R8 just has fwd like understeer. Took me only 10 min to cure that problem and have an overall stable setup.
