This week, i'd take a break about setup for specific track,
but i analyze
the wings/spring relation and i found a very
interesting thing.
First, i would like to thanks Fred Deyrieux who
help me a lot by sending
to me 26 TLM files from 0-0 wing setting to 25-25
wing setting. With
these TLM files i could analyze them very closer.
For now, i have a first conclusion: the
suspension travel have a direct
relation about your spring setting.
Here is an example:
wings setting 5 front and 5 rear
at 50 % spring R and F suspension travel are 26 F
and 69 R.
at 75 % spring R and F suspension travel are 17 F
and 45 R.
at 100 % spring R and F suspension travel are 13
F and 35 R
These results were taken from Hockenheim after
the exit pitlane just
before the chicane near 21~22 second at full
speed and throttle.
I use 100 m ride height F and R for these tests.
so it seem that at 100 % spring the maximum front
suspension travel is
13 mm with wing at 5 F and R and 35 mm for rear
suspension travel.
13/17 = ~75 % and 13/26 = ~50 %
and
35/45 = ~75 % and 35/69 = ~50 %
how could you use it ??
suppose that you choose 5 front and rear wing and
you set your spring
like 68 % front and 57 % rear.
your basic value for 5 R and F wing is 13 mm and
35 mm for your
maximum suspension travel.
13mm/68% = 19.12 mm your new maximum suspension
travel for 68 %
front spring with 5 front wing
and
35mm/57% = 61.40 mm your new maximum suspension
travel for 57 %
rear spring with 5 rear wing.
How could be your ride height differential
setting between front and rear
??
answer: 61.40 mm - 19.12 mm = 42.28 mm
So if your front ride height is set to 30 mm, you
will set your rear ride
height to 30 mm + 43 mm = 73 mm if you don't use
bump ***s.
So as soon as possible i will post on my setup
page a table for each
possible wing setting to help you how to select
your ride height
depending on your R and F spring and your R anf F
wing.
Boy - engineers huh? They live in a different world :)

Thank goodness for the rest of us. I wouldn't want to drive even a
simulation of an F1 car at 300 km/h with you or I responsible for the
engineering.
