Permanent changes to a car. Rigidity and flat floor. Worth it?

In GT5 I did some testing and most cars cornered better without the rigidity upgrade. I am hoping somebody has done lap times and has a general consensus on whether its worth it.

Flat floor seems to increase drag on your car by crazy amounts. It kills your acceleration and top speed by a huge factor. I have never seen it worth it on a car, on any track.

Thoughts?
 
I installed the rigidity upgrade and a rear wing type (D) to the Acura NSX '91 and improved the lap time with that car to 2:24.885 from a 2:28.762 at Ascari. This could be due to the fact I'm learning where to push the car and therefore not conclusive. EDIT: Currently, 47.0 miles driven in that car.

I have noticed that cars with Improve body rigidity are not experiencing degradation at the same rate as stock cars
 
The flat floor kills some accel. and top speed but makes the car corner so much faster (more planted and grippy), so in more technical tracks its worth it, plus when high PP is allowed and your car is powerful enough, it is a very good option for more down force.
 
I haven't tried since the update but flat floors are not permanent and are not worth it. Flat floor take around 15-20PP and the trade off is not worth it. Maybe if your racing a the GT arena. Rigidity seems to be just like GT5 where it adds understeer. So if you car has horrible oversteer you can use it. I have only a handful of cars I needed to use it on.
 
I just started using these upgrades on a few cars, I have purpose built an '02 Viper and a '14 C7 to race car specs for GT3 class races using the flat floors and body rigidity. Neither of those cars really need more power, I only used exhaust parts and weight reductions to tune to 599pp. The result was really stable cars that could put significant more power down in turns. Both of the cars weigh in at 1240kg with roughly 580hp and perform just as well, if not better than all of the gt3 cars with no additional tuning.
 
I did the rigidity on a few cars in the case of a Nascar I did not see any difference in lap times, int he case of the RUF BTR I saw better lap times, I would say as a general rule of thumb you will see the most difference on street cars with soft suspensions and less in race cars with hard suspensions
 
I don't trust Body Rigidity Upgrade. Never had. Mostly because of the tight feel and understeer it gives. flat floors are undoable thankfully. I haven't noticed how much this affects the car other than the looks. Maybe because I haven't compared before an after. I do notice my Viper ACR behaving more like a racecar, especially on high speed corners. The steering becomes much more responsive than in a street car, compared to the ACR in GT5. Don't know if this is caused by the flat floor though.

As for PP, I never pay attention to this number, so I haven't notice an increase when fitting the flat floor.
 
Improving body rigidity shaved a second off my lap time with my R18. Flat floors helped alot of the street cars that I gave handle a lot better.
