RISI COMPETIZIONE LIME ROCK 2016 GTLM PREVIEW
A Race Engineers' Perspective
Risi Competizione Ferrari 488 GTLM No. 62: Giancarlo Fisichella (ITA)
Toni Vilander (FIN)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(Houston, Texas, July 18, 2016)...Rick Mayer, race engineer of the Risi Competizione
No. 62 Ferrari 488 GTLM team, gives us a preview of this year's Northeast Grand 
Prix Prix race, July 23, 2016, at Lime Rock Park in Lakeville, Conn.
Giancarlo Fisichella (Italy) and Toni Vilander (Finland) will drive the Risi Competizione
Ferrari 488 GTLM at Round 8 for the International Motor Sports Association (IMSA)
WeatherTech SportsCar Championship series, Round 7 for the GTLM class. They recently
finished sixth at the Mobil 1 Sportscar Grand Prix race in Bowmanville, Ontario,
 Canada.
General: We'll have 31 cars at this small 1.47 mile 7-turn track, making practice
and the race a bit congested. Clear laps will be few and far between with a quick
GTLM lap of just over 50 seconds. Traffic is always a big issue here, especially
 in the chicane which has been a major source of full course cautions since we changed
to this configuration. The faster cars don't want to be stuck behind the slower 
cars through the chicane and occasionally make risky moves entering that corner.
Track particulars: We'll run the same circuit configuration as we did in 2013, which
was the last time the GTLMs were here. Lime Rock had a recent re-pave so we're not
sure how the surface is now that it's seen a couple winters. It will still be all
right turns with one left plus the chicane. The chicane curbs are important for 
a quick lap time. Turn 1 will be the biggest passing opportunity, and the hill leading
down onto the front straight will be important for a good run onto the straight.
 This corner was not flat (full throttle) for GT cars in 2013.

Setup: We'll try and run as low as possible. We may have to add tilt (left side 
of the car higher than the right side) if we touch too much on the downhill Turn
 7. Depending on the car and driver requirements, you'll also run some cross weight;
normally more right front weight will let you trail brake longer (or more aggressively)
into Turn 1 without inside front wheel lockup, and it also helps reduce the mid 
to exit under-steer on right hand corners. We'll run the cars a bit asymmetric as
there's only one left hand turn. Think of this track as a right turn oval. We'll
 spend some time optimizing the chicane as its important for lap time. It goes without
saying you run maximum down force here, top speed is quite low, about 150 mph. For
GT cars that means running as much wing (rear down force) as you can balance with
the front downforce. More downforce at Lime Rock increases the exit speed in the
 last corner and actually increases the front straight top speed. Trimming aero 
actually reduces top speed here. The two key corners are the first and last; you
 need a good exit off the last for maximum speed on the straight and good braking
and entrance stability into Turn 1 to overtake.
Competition: Any of the five makes could win here: Ferrari, Corvette, Porsche, Ford
or BMW. The recent Balance of Performance (BoP) change will still have the Ford 
ahead, closely followed by the Corvettes. The BMWs are always fast here and still
have a favorable BoP. Porsche is changing dry tires; they will have their tire choices
from 2015. This tire range seemed to suit them better than the 2016 Michelin tires
that Porsche developed and tested specifically for their car. The rest of the GTLM
field will be using the 2016 tires that we starting using at Laguna. Top speed doesn't
come into play here as the track is so small and the straights short; it's all about
getting the setup right with the limited test time. The teams will only have two
 one-hour sessions to sort out the setup, which is 60 minutes less than a normal
 sprint race practice time. And practice stoppages are common here, particularly
 with 31 cars and 22 being Pro-Am.
The race: Calling the race (race strategy) with the cautions is tricky here. The
 green lap is so short that the caution laps are only ~100 seconds. It takes roughly
30 seconds to traverse pit lane, 28 seconds for a full stop.  Depending on your 
position in the queue behind the pace car, there won't be a lot of change left from
the 100 seconds. You can easily go down a lap if you get it wrong, even on a good
stop. A green flag stop will put you a lap down.
We'll start with a setup based on our previous Lime Rock notes and hope its close.
It's a new track for Giancarlo and Toni's last visit here was 2011. But it's a very
short lap and a relatively easy track to learn. It's hard to pass here and hopefully
the Risi crews' quick pit work can push the Risi Ferrari forward or if you're an
 optimist, keep it up front!
