400m Suspension settings

[1989therat]

I've spent the last hour testing the suspension settings of a car doing the 400m.
I would hold the N0S and the gas down and look at my times. Heres a general way to setup a car for 400m. It improved my times by 1/2 second in a 838 hp 3000GT MR.

Spring 15.0,2.4
RH: 175,96
Shock Bound/Rebound 1,1,1,1
Camber 0.0,0.0
Toe -4,+4(this shaved off .152 sec alone!)
Stabilizer 2,1

Downforce Front: lowest
Rear:Highest(even though this sounds like a generalzation it really works.)
VCD: Doesn't do a damn thing.
TCS:9 (10 slowed it down...so did 8,7,6,5,4,3,2,1,0)

Hmm...I'll have to try those out. You can also use the tranny trick (search for it; I've posted in another thread on how to do it correctly) to improve your times by 2-3.000 more.

lol..thanks anyway but I already know almost every trick in the book...
1000's of setups
I'm in the Top 10 list

In GT2 there are other tranny trick that is faster than usual tranny trick.
on Trueno BZG '96:
27.697, using common tranny trick just like in your link
vs
27.204, using reverse tranny trick, never see anyone else use it or care about it YET.

Since you know much in gearing, can you tell me do small final drive is faster than big final drive? Nobody answer me before and I still don't have a chance to test it.

I sometimes use the reverse trannytrick for top speed testing, but it´s not feasible on all cars. Some do better with the normal trick, and some do better without any trannytrick at all. I assume the same goes for 1/4 mile runs, but I haven´t done alot of those.

The reason reverse tranny trick is faster than normal tranny trick is because smaller final drive behave like lighter flywheel in GT2. On many race car (and skyline) this will only slowing the acceleration for different reason, the flywheel is too light that it makes the engine stutter on mid rpm.
This work on all track. Average 1 second faster lap time in GT2 for reverse vs normal tranny trick.
If this work in GT4 then you should be able to increase your 300mph car to atleast 5mph more.

True to some extent. For this kind of top speed trials, torque, or rather torquerange, has great importance. When you shift gears, you want the next gear to start its drive within the desired torquerange, so depending on where that is, the trannytricks will have different effects. For cars with a high range, the reverse trick seem to be the best option (ex. Audi R8), and for cars with low to mid range (ex. Nissan R92CP), the normal trick is the best. And for some cars, the desired torque will be screwed up if you start doing any of the trannytricks (ex. Bentley Speed 8).

I think that works if we use automatic or always shift at highest rpm. If we shift at optimum rpm range we should be faster using short gearing. This is an example from my 1000m in plymouth roadrunner muscle car.
21.657 = time using normal gearing and auto (shift at 7000)
20.284 = normal gearing but utilizing powerband (shift at 6000rpm)
19.986 = reverse trannytrick and utilizing powerband (shift at 6000rpm)

I usually make my gear drop to higher rpm on higher gear after shifting.

BTW, my reverse trannytrick is as short as common tranny trick (same all gear speed), the difference is in the end finaldrive.
And, how can I get power figure like this in GT4, I can't find it in setting screen. If this do not exist in GT4 then it really a major drawback, because I always use it to decide at what rpm I should shift.


*edit: nevermind, power figure exist in GT4 I just don't notice it (My first forum search is using "figure" as the keyword, and it turn out I have to use "figures" as the keyword as both word treated differently )

5) Settings Screen (screen that appears after clicking on the Settings icon, before a race) - (Power is shown in the big Power and Torque Graph, which can be brought up by pressing Start)

I think its better to:
- shift at optimum range than
- shift at max rpm and let the gear drop the rpm to optimum range.

We use the optimum range more in first case as we use some non optimum range in second case.

You´re right, but for pure top speed, normal logic has to be set aside. If you want to see this for yourself, try out the settings found in my sig. Then change the gears (and shifts) to your own preference and see if you improve.
For 1/4 mi runs, your way is the optimum for sure, no doubt at all, same goes for track use, where I utilise your method on regular basis. Of course depending on car and track, wich method used differs.

Ok, I'll try when I get the chance
