The answer is no, but here's how to make your own setup faster:
General Comments:
Cross Weight (Wedge)
It's important to note, you'll notice in the recommendations below
that I only mention cross weight (wedge) as a solution in the exit
phase of the corner. The biggest problem I see most people having is
being loose on exit. The problem is most prevalent at flatter and
smaller tracks like Salem, USA Int'l, and Milwaukee. The best thing
you can do if you are loose off the corner is to keep adding cross
weight until the car will drive smoothly off the corner. Once you
find that cross weight balance leave it alone. Use other setup
parameters to correct handling in other phases of the corner. As you
reach a good neutral balance through the entire corner you may adjust
cross a bit, but only use it to correct corner exit problems.
Left rear spring rate also has a significant affect on corner exit
balance. Cross weight adjustments are a bit more coarse than left
rear spring adjustments. If you are just a little loose or tight on
exit just try adjusting the left rear spring a click or two in the
appropriate direction.
Driving Style
Another problem I see occurs when people over-drive the car into
corners. A symptom of this problem is excessive right front tire
temperature. If your right front tire is hotter than the right rear,
you probably need to adjust your driving style. The two ways to
improve your driving style are to A) slow down more before approaching
your maximum turn rate, and B) use less steering wheel input. If you
do 'A' then 'B' will naturally follow. So, slow the car down more on
entry, get the right line through the apex, and you can get on the gas
earlier. This is the key to going fast. The result will be lower
right front tire temperatures, better tire wear, and faster lap times.
ARCA Sim Racing Setup Cheat Sheet:
These setup suggestions represent a conventional approach to chassis
and suspension setup. A 'Coil Bind' or 'Big Bar - Soft Spring' setup
approach may differ significantly, and is beyond the scope of this
document. While there are a few things here that may be specific to
ARCA Sim Racing, almost all of this applies directly to real life car
setups. These recommendations are what works best for me in ASR based
on my own experience.
Air Pressures
Qualifying - at end of run:
- Middle temps should equal or slightly exceed inside edge (relative
to track) temp.
- RR middle temp should be 10F hotter than inside temp.
- The right rear tire temp should be about 10F to 15F hotter than
the right front.
Race - after 10 to 20 laps:
- For long runs middle temps should equal average tire temp (M = (I+M
+0)/3).
- The right rear tire temp should be about 10F to 15F hotter than
the right front.
- For short races apply qualifying guidelines after 10 to 20 laps.
Camber
- Set front camber for a 10 to 15 temp spread across tread with the
inside edge (relative to track) hotter.
- Set rear camber to full
For the completely clueless:
- Oversteer = Loose = The rear tires lose grip first.
- Understeer = Pushing = The front tires lose grip first.
If the car is pushing, you need to increase oversteer. If the car is
loose, you need to increase understeer.
