Sorry to have missed the round last evening, chaps.  I rather overdid it for dinner and as post time approached, I rapidly spiraled down with lethargy and went to bed early.  Never learn, it seems.

Grats to Paul on the victory!  :)

Thanks for that input, Jimmy, Tom.

I ran the Matra MS11 V-12 car with 1°F/0°R.  The small front wing angle was an effort to help pin down the front end in the tight corners.  It's not the fastest car in a straighline but seeing as how virtually all the corners here at Keimola are quite slow, I figured that tuning for top end would pay dividends.  I did precisely the same quite a few years back at this very circuit in our GP69 cars where I used the Ferrari 312.  I was able to set reasonably competitive times and was a bullet on the straights.  I was nowhere in the GP68's in our two races here and can see by comparing speeds in GPLRA that I'm losing all my time in the corners and by a bunch.  I strongly suspect that by merely dialing in wing angle, you get downforce regardless of speed.  Aero doesn't work that way.  You need to be above about 70-80mph to start seeing benefits.

I'm going to conduct some tests at Keimola with my Matra on different settings and some other chassis to see what I can make of things.

Thanks again for the input, chaps.

Hi, fellas.  I'd like to canvas the membership to learn what wing settings you employed for our Keimola races.  On a circuit where the vast majority of the corners limit speeds to barely 60mph or even less, theory says that aero downforce and adhesion should not figure.  I'm concerned that this mod gives you downforce regardless of speed and that shouldn't be the case.

Nifty, Bob!  Thanks for composing.  I'll be going over it carefully in the next day or three.

Hmmm...

As far as I know, there are performance changes between the sets as the late version incorporates downforce.  I'm using the same driver persona across the board.
