Flat Floors question

[Voodoovaj]

I've seen mentions of flat floors, but I thought it would be good to have a dedicated discussion. I've heard some conflicting things about flat floors and I've seen odd behaviour.

So, here's my scenario:

V12 Vantage - 550pp - With RS tires I'm lapping around Ascari in high 2:01's - 2:02's

V12 Vantage - 550pp - With a flat floor - lapping mid 2:04's

V12 Vantage - 576PP - So I set it up the same as the 1st example, but added the flat floor ...

High 2:02's to low 2:03's

WTF do flat floors do?????

Nice posts for the lap times. I too have been trying to find the advantage to using them. I have tried some similar tests...I have it installed on an M3, but for the PP it doesnt translate.

My understanding is that it is an aero increase, so cornering speed should go up at a heavy cost to straight line speed. I don't have numbers to throw out but I had a flat floor on my FR-S and I noticed it was struggling on the straight at Grand Valley while I was progressing through the events. Since I had it on mostly for looks I took it off and I felt the car was a little less solid but faster overall.

I was going to ask the same question. So far I have found that I have a lot more grip through corners. I have one installed on an S2000 which bring it up to 530pp on sports soft tyres and the handling is superb, no wheels spin at all really.

I also had one on a Honda Civic at 450pp, sports hards and there was a lot less under steer.

I would say that they are good for short technical tracks where top speed isn't an issue. But then again I'm too sure, I haven't thoroughly tested it, I'm hoping somebody else can give me the answer.

That's what I thought too, but the laptimes say otherwise. I was expecting the 576 car with the floor to be significantly faster than the 550 without, but no floor seems to be the way to go.

Maybe the floor works with camber

Perhaps the best benefit would be to those cars that oversteer wildly or have erratic cornering behavior or older cars with limited grip available through (suspension) tuning?

Yellow Bird?

Of course many of those are Standard, to which such riches aren't available should you wish to try it out .

Naw, my yellow bird grips and handles awesome...I wish it more horsepower and less torque

In game yes. In reality, they boost straight line speed too.

Depending on how the floor is modeled (which appears terrible) the center of pressure could be far back, which would make the floor good for rear heavy cars or oversteery cars. Given how the flat floor is not remotely realistic, I wouldn't bet on this being true other than through coincidence.
