I was watching the espically sleepy Indy 500 practice on Tuesday May 13,
when I heard Jan Beekhuis say something about the setups used to get the
pole and whatever.  He said, "Most of the high-qualifiers have
high-downforce setups."  I got a setup from Marc J. Nelson, and incresed
the downforce heavily, about 6 deg. per wing.  I got the cornering that
was a key at Indy ICR2, but unfortunately, it slowed me down considerably.
 I decreased it to 7.00 rear and 7.50 front, but it wouldn't corner good,
while still going faster, IRL speeds for example.  Can someone build on
this high-downforce thingie and still keep the horsepower?

It depends on what you call high downforce.

I think, from reading your past posts, that you have a misconception that
Indycars take a lot of corners flat out.  This is not necessarily true.
Michigan is a flat out racetrack where Milwaukee is not.

Indy can be taken flat out, but is sometimes a slight lift (no braking,
just coasting).

I am a high downforce fan, so my setups tend to be quick in the corners
and fair down the straights.  As an example, my Long Beach setup has high
downforce only allowing me a top end speed of around 188 or so, but I am
so much faster in the turns that I am turning laps in the low 51s range
during Q and low 52's in race trim.

My Indy setup has a FW of 5 or 5.2 and a RW of 4.0 or 3.8.  This gets me
to 240 in the straights and about 222 in the turns for a lap of 232, or
so.  The heavy wings compensate for the lack of mechanical grip that I
haven't quite found yet.  If I get the entry correct I can take it flat
out, but if I'm off slightly I have to lift.

My modem partner enjoys mechanical grip so carries less wing and turns
laps in the 234 or 235 range.  He's not much faster down the straights
than me, but doesn't scrub off the speed as easily in the corners.

Actually, as the aforementioned modem partner, I can attest that I am
using MORE wing, not less... I am fast down the straight because I carry
more speed off of the corners.

  Gads you two can motor.  Anyhow remember that the cars modeled in
ICR2 are only remotely similar to the cars currently running in the
Indy 500. So what Beekius said was true for the IRL cars, but the
CART/PPG/INDY Cars modeled in ICR2 attack Indy very differently.
