I'm just returning to GT world and remembering how frustrating this endless loop is:

1. Setup
2. Go track
3. Repeat

I'm concerning about something I've being seeing here, several car setups with downforce set at maximum even among those some considered "Gods" of tuning.

Is this setup better with your car glued on track? What about top speed and performance?
My personal opinion is that any other setup in this game, downforce shouldn't be overused.

What you guys stand for about it?
 
Well IMO it depends on the car and the track you are going to use it on. In some cases you would not want any downforce at all and in other cases you may want more than the max.
 
More downforce will mean faster lap times almost all of the time. No problem with setting high downforce or max downforce.
 
Like I said it depends on the car and the track.

Downforce reduces your acceleration and top speed but increases the potential for speed in corners. Some cars are not fast enough to need any, especially if you are using good tires, other cars are so fast they can't live without it on most tracks.

Example If you were tuning a car to run on Daytona Speedway you would want to use very little if any downforce because the cars can handle the banked corners there without out it and need the speed as it is a very fast track. Motegi speedway on the other hand requires downforce because the corners are much more difficult to take at speed and you need to maintain as much speed as possible through the corners to get a fast lap. Indy speedway is somewhere between the two.

Lemans is a very fast track and you need speed more than cornering so little downforce there where as a track like Tsukuba would need some downforce for the high speed corners. In many cases I would use full downforce here.

Nurburgring is a hard one, you have both high speed that will suffer with downforce and a lot of high speed corners that will benefit from downforce so here it largely depends on how you drive and of course what car you are using, A fast car will want some downforce a slow car no downforce.
 
Downforce also depends on you driving style. Personally, I like a relatively low rear downforce, and a high front downforce. That way the car turns in sharper and rotates better on high speed corners. But, it mostly depends on the track, at Monza and Daytona Road for instance I am fastest with minimum downforce, but on other tracks such as Brands or Suzuka, I am fastest with a high front downforce and a rear downforce around the middle.
Edit: BTW that's with the R8 LMS

That's completly ignoring aerodynamics drag harmonics !

Try my 908 drag tune on Road X and put the aero back at min/min... You won't hold the straigth (!!!) in like the wind on Road X with cars behind you (!!!).
With max/max, same story aswell (I agree it's stupid on a drag tune but max/max doesn't mean "stability" without taking in account wind harmonics at very high speeds - 440+ km/h :))

Seriously try it, this is not magic and I was very surprised and impressed me too ! There's wind hysteris phenomenons now ! :)

The aero model changed A LOT from GT5 so max/max is no more a mindless setup as it was before !

I liked it better in GT5 where downforce added to the PP level. Then it mattered more. For most tracks without the monster straights, more downforce works. I find that I am backing down the rear number to help encourage corner rotation. I also do not add wings to any street cars because most of them need more front grip, not rear.
