Induced understeer works GTR2
 

At least one noticable change in the physcis between GTR and GTR2. When slowing
(lift throttle) or braking, and the rear end steps out, you can steer inwards
to cause the front end to plow, to correct the oversteer (driver induced
understeer). This rarely worked in GTR, but it works well in GTR2.

For acceleration, normal counter-steering (outwards) and throttle modulation are
still required.

For some real racing cars that don't have downforce, when cornering at very high
speeds that require full throttle to maintain speed, a bit of induced understeer
can help stabelize a nervous car. Some players did this with Grand Prix Legends.

I think the effect was a little overdone in GPL.

Seems to me the physics in GTR2 are greatly improved over the first
version in general. Racing in the rain is really cool , they did a
very effective job with the sound of the rain,thunder,and the physics
of driving on wet pavement. To me it is the rain thing in GTR2 is the
most amazing achievement of any sim ever and I have tried them all.

The cars in GTR2 have immense downforce. Not as much as an F1 car but
several have better downforce:drag ratios (thanks to the fenders).

You mean the stab save? I always hated that.

The cars in GPL, 1967 F1 race cars, rearward weight bias, no downforce, high
working slip angle, are probably ideal for using induced understeer. I've
read that the Lotus team manager heard Jim Clark describe using induced
understeer, with the manager responding, that's why he's a manager and not a
driver.

I've asked some club level race drivers about using induced understeer, and
although it's not needed on most cars, there are a few where it's used.
One guys comment is that his Clio was evil, and he had to use induced
understeer, to keep the car in check on high speed turns as I mentioned.
Most guys that get to run their cars on ovals for fun end up getting large
rear wings to keep their heart rates in check.

GPL did have a induced understeer quirk, on the Lotus, if braking balance
was around 53%, you could get a reverse steering yaw reaction when braking
hard. Also using front toe out could be used to keep a car stable under
heavy braking. I made a video of the reverse steering reaction, although
the video only shows a left yaw, I could steer left and get a right yaw
on the same section of track:

The worst "offender" of induced understeer was with LFS S1 all or nothing
grip factor, especially on the LX6:

Induced understeer used properly (just a bit) and coutner-steering, Rouen
by Greg Stewart. Tires inwards while slowing, outwards while accelerating,
inwards on the very high speed right sweeper. After the 90 degree left
haipin, the next two acceleration right turns are done with the steering
spending most of the time left (throttle oversteer). The bottom (chase)
view of this video give you a good idea of what is going on.

I used to love the rain/thunder sounds in Monster Truck Madness 2 :)

Very little on my system. At 1280X1024 I get a 4-5fps hit in rain with most
video at high or max levels. 3.6ghz EM64T Intel and ATI X850 PCIE graphics.
All in all GTR2 is about as demanding as GTL on my system. I always get this
stuttering when pulling out of the garage in GTR, GTR2 and GTL..........
Other than that all is, for the most part, very smooth.

OVERCLOCK IT!! Hahaha. Is your X850 pro or XT or regular? Mine is AGP so
I was able to unlock the 4 extra pipelines so now I have 16. :)

Did that. Running mem @ 620, GPU clock @ 540 and very stable. Mine is the
X850 PE already at 16.

FYI something bad wrong in vid?

What the 'ell is wrong with this vid? I cant play it, jerky as hell, takes
100% processor time, dang near locks the whole system (yeah your right is is
probably SSDD Microsoft..)

checking now if all new ones are this way, but I had viewed a lot of your
older wmv & mpegs you ve posted... hoping it is not just me... lol

Nope, just the GPLRS.WMV I cant play...

Next 2 played fine though...
