  I have started racing the Lotus lately and tonight I stumbled onto
something that I didnt think happened in GPL.After 10 laps at the Glen
my car would start sliding on right hand turns.Braking and
accelaration suffer too.Crashing is inevitable.After 4 restarts I
decide to look at my tire temps and they are reading 270deg for the
left/rear and 260 for the left/front.So I start taking it real
easy,trying to stay behind the lead car to serve as a reference for
how quick to take the turns.I turn the front wheel as little as
possible and am actually easing off the throttle when I need the car
to turn more instead of more lock.I am also trying for the least
amount of tire squeal I can possibly do.I am only doing lap averages
of 1:06:XX with occasional dips to the 5's.The best out their are
doing low4's so I cant see how Im pushing the car too hard.I am using
the default Lotus setups with gear,brake and ride height changes
only.Is it because you just cant run 17 laps in the 6's.The really
fast are doing low 4's at the Glen.Do they race at those times or is
this a hotlap setup only kind of thing??One thing I am noticing is how
you start to really sense the car on its edge of traction with
practice even with the limited tire squeal sounds GPL has.Tire
overheating and its affecting grip levels has probably happened to me
before and I just never noticed it.

.So I start taking it real
More lock does not mean the car will actaully Turn more.  At some point the
car will only scrub speed and heat tires up. If you are beyond the proper
slip angle and the tires is not addressing the road properly, you will
basically not go any faster and really chew up tires.  This is true in GPL
and in my real race car.  Its a wierd concept, and very hard to learn and
do.  If car is understeering a lot of times steering more will not make car
turn better, but by letting out some lock will actaully make the car go
thru turn faster.  Remember you may only need to let out a little bit.  In
my real race car it has been so dramatic that at a Autocross I was fighting
understeer really bad in one corner and finally let out some steering lock.
The car scooted thru the corner some much faster i was not even on the gas
at apex.

I am also trying for the least

You can do 17 laps in thte 105 range,  you just need to be smooth with the
car.  the BRM is the only car that I have had problems getting 17 laps out
of and my lap times were within a second of eachother.  The BRM will really
teach you how to conserve tires, since its so heavy and will use tires up
fast.

You make a great point.  All teh guys that run the hard setups cant run them
for long due to tire wear.  I never thought of it because GPL simply doesnt
have tire wear, just temps.  That is also how it is in real life, stiff
suspension handles great but tears up the tires, so maybe GPL is really
modeling everything correctly (well maybe not the toein/out maximums).  I
guess that also shows why at a race at silverstone my braking kept getting
worse and worse and I started going wider and wider in my 30 lap race,
finally found some strategy for those long races.

260 degrees shouldn't have your car sliding too much. 300 degrees is
the limit. At that temprature, your car becomes undrivable. It is very
abrupt too. Get one tyre temp to 300 and you'll immediatley start
doing spins while cornering.

The primary reason why you would get it to 300 is running front and
rear bars at 200 on a twisty circuit. 200 f+b at monza or spa is ok,
cause the tyres cool down on the straights, but at zandy, they
overheat within a few laps.

At a place like zandy, monaco, watkins glen, the maximum rollbart that
can be run without overheating is 150 f+b.

This will help, and it's most noticalble at a place like monaco.
During braking for the hairpins, you can pull on some lock, but your
car won't turn in till you have scrubbed the speed off. I believe it
may even increase braking distance, cause your fronts are now sliding
instead of being on the braking threshold of grip..

Therefore it usually is better to wait till you can turn with grip,
rather than power it though, sliding all the way...off the track :)

I can only speak for my own experiences, but all my "hotlap" setups
are actually race setups. The exception being my zandvoort setup. The
zandy setup is only a hotlap setup, and is exceptional hard to
control, even for me :)

In most races, we run consistant laps within about 1/2 a second of the
WR. The exceptions being the long tracks such as spa and the ring.

A quick idea of what i mean, in the GPLWS race at watkins glen race
number 2, I did four***, 1m04s laps, with the best being 1m04s10. The
other few where a 1m09(start lap) 2 1m05's and a 1m06. And I still got
beaten by wolfgang by 0.27secs :)

Sensing traction, is mainly by sound. You can make the tires squeal
quite alot, and that is where the most speed is. If you watch one of
my hotlaps, you will see how on the edge I am, and during races, I am
quite close to that lap, every lap.

 Yes,this has been what I was doing.Everytime I release the throttle I
ease off the lock alittle since the weight has transfered foward
slightly.I have placed a piece of tape on my monitor and have painted
my***pits to have a white line down the centers.This allows me to
see the***pit shift better.How this helps is,without concentrating
on it,I only turn the wheel enough until I see the***pit line shift
off the center line on my monitor.This gives me a good sense of the
car taking set and then I feather my steering from this point.The tape
has really helped me in that before I was using way too much steering
lock for the turns since these cars dont turn-in well and I figured
this was because I wasnt using enough lock.

  Wow is all I can say.I have all of a sudden been doing consistent
5"s,same track,car,setup and race length.Not too much tire squeal and
a perfect entrance to the ninety did it for me:))Thansks for the
suggestions.

 Yes your right that 260 is driveable but you need to be able to feel
these difeences  to adjust to it.I hit 300temp and the car would not
accept any power.

  Yes in a real car you will be able to feel this effect of the car
not turning in because all your tires available traction is being used
for braking.In a sim we cant feel this just yet.Since feeling this
effect is impossible with todays sims I notice alot of GPL cars
understeering heavily into turns because of too much braking
force.Excellent FFB will cure this since easing off the brake will
make the steering start to grip and well be better able to ride this
edge of front tire traction:)

 I like to turn -in and then release the brakes to try to get some
turning traction.

- Show quoted text -

 Sounds to me like a blast.I am finding that as I improve I am
enjoying racing the AI more and more.I now look in my mirrors and try
to think strategy.I feel the best way to get really good at GPL is to
get your times down low so the AI is doing super fastlaps then trying
to come off corners faster than them.My polesitting AI qualified with
a 1:04:XX.I stayed behind him and can get a very good sense of what
makes me come off a corner faster.I set my fastest time at the Glen
tonight by doing just this.By Pointing the car towards his inside I
could get on the power just that much more quicker and pass him for my
ultimate time of 1:05:01:))

  Yes I noticed this alot by watching dave Mansell's hotlaps.He takes
his car so hot into turns that you hear his rear squealing most of the
time thru it.I am gonna check out some of your times tonight.

Hehe me too.GPL is not totally realistic in terms of car setups and
there is much room for improvement.I have noticed many faults in the
GPL garage.This doesntreally matter in racing the cars though since
its just numbers in the garage and you whats supposed to happen by
changing a setup option actually happens..The fact that you can go
from a 5in ride height down to a 1in and have the tire temps remain
the same on both sides of the car is dead wrong.In real life the
higher trhe center of gravity the more weight will transfer so the
outside tires will go overload andthe inside will not be used as
much.The net effect of this is less overall grip.Lower ride height
means less weight transfer and your inside tires have more weight to
grip with.This doesnt really matter because in GPL the car behaves
like it should by having more grip with less ride height but it just
isnt being modeled into the tire temps.Theres other things too but as
papyrus stated they cant put it all in since it takes to much cpu to
calculate this stuff eprfectly.I wish someone would figure out all the
things that are perfectly modled in GPL so we can work from there in
our setups.

What you people fail to realise is that the range of setups and
adjustments provided in GPL far exceeds anything that was actually done
in real life.

Between races there was little done to the cars other than (possibly)
changing gearbox ratios for the next track.  Testing of cars was almost
non-existent unless a major change had been made to either design or to
engine.

The ride-height adjustment in GPL is fictitous when related to real
life.......this huge range, from an inch to six-inches ground clearance,
is science fiction!  Average ride-height was in excess of four inches
and adjustments to spring/damper settings were extremely coarse compared
to those presented in the simulation.

So if you want to criticise GPLs accuaracy, it should be directed the
other way....that the simulation provides adjustments far beyond what
were available in real life.

  I am not trying to downplay GPL at all.I love GPL!!!I marvel at how
realistic the driving model feels.I watch in amazement at how
realistic this new physics models looks when I watch the racing from
outside my car.I only paid $25 dollars for my beloved copy since I had
the origional Electronics Boutique ad.I cant believe all the nights of
enjoyment that this small purchase has given me.I have been driving
GPL since the first night the demo appeared and it has been becoming
even more satisfying the more I drive it.This game has forced me to
make a homemade wheel/pedal setup thats good enough to take nightly
abuse since the bungee in my T2 constantly loosened up and the pedals
were awful.I have upgraded to a 450mhz pc with a 21in monitor just for
GPL.I am seriously thinking of buying the Game Frame Pro cockpit from
Ball Racing, "just" for GPL.Believe me I am not downplaying this game
or should I say sim?I was just pointing out that this is not the
ultimate in physics modeleing.Theres still many things that can be
added and I for one feel this is something to look foward to in future
Pay sims.The roads are smooth as silk in GPL and most likely N3 and
this makse alot of the setup otions not work the way they
should.People are running very stiff suspensions with super low ride
heights since the GPL world doesnt model bumps on the roads.You better
believe I am running an unrealistically low ride height at all the
tracks too.The way I look at it is I am using every means of car setup
to go faster in the simulated world of GPL.When we finally get these
bumps in the roads,setups will be very varied and realistic.Wanna go
fast then stiffen up those springs but have to deal with the fact that
your tires will now skip across the road on turns and not grip as
well.Something I noticed in the demo that I dont in my final copy is
that I could swear there were bumps at the small downhill section
before the ninety/Glen.If I would brake just at the limit of edhesion
in the demo my car would sorta skip down the hill but this never
happens in my final copy.I dont have the origional demo anymore so I
cant try it to make sure I wasnt imagining this.High frequency bumps
are defenitley something to look foward too in future sims to hit the
market as is FFB wheels,pedals,VR systems and motion simulators:))But
GPL is so realistic as it is that as I have said I spent lots of mula
to enjoy it as it should be played.
