Tuning tutorial

here is all you need to know for squeezing the max out of your car

–––––––––––––––-
SUSPENSION:
COMPRESSION RATE:
Softer means you can feel no bumps (usefull for speed races where your car is totaled with a small bump)
stiffer means better handling and response

REBOUND RATE:
how fast your suspensions returns to its original length after compression
stiffer means it expands fast so you have more bumps, less handling and vice versa

SPRING RATE:
stiffer ads cornering ability anf softer helps u soak the bumps

RIDE HEIGHT:
setting the car low adds handling, cornering ability and stability
setting it high u have more air pressure below the car (good for making wheelies), max speed, and accel.

ROLL BAR STIFFNES:
this is pretty advanced and it's used to fine tune your car's behavior:
bigger roll bars at the rear makes your car oversteer (aka sliding with the rear end)
bigger roll bars at the front gives you understeer (aka sliding with the front end)
*hint* if you've got a car that has huge oversteer, increasing the size of the FRONT roll bar, won't make
the car slide with both ends :rolleyes5
it will just reduce the understeer ;)
same with understeer

TIRE PRESSURE:
low pressure gives you grip and high gives you top speed and accel.
*hint* you can also use this to fine tune your car. more pressure at the back will make the car
oversteer. more at the front will make it understeer. you can use this to reduce your car's
over/understeer by increasing/decreasing the tire pressure

TOE:
setting it to negative (right) makes your car response quicker.
setting it to positive (left) makes the car more stable

CAMBER:
positive–> more grip, less top speed and accel.
negative–> exactly the opposite

CASTER:
positive–> stability, max speed
negative–> cornering ability

STEERING RESPONSE RATIO:
how fast your car responds to steering

–––––––––––––––––––––––-

CAM TIMING:
advanced timing: more torque at high rpm (aka better accel at high rpms)
retard: more torque at low rpm's (aka better accel at low rpm's)

BOOST:
-START BOOST: how much power at the start of your rpm qurve (quite the same with retard timing)
more boost = more horse power = less max speed = more accel
-END BOOST: how much power at the end of your rpm qurve (same with advanced timing)

NITROUS PRESSURE:
more preesure = more boost (aka more power from notrous) but it rouns out faster
less pressure = less boost, runs out slower
*hint* at drags use more presure (u get more power, meaning bigger wheelies and accel.)

NITROUS FLOW RATE:
bassicaly it has the same effect with nitrous presure.
––––––––––––––––––––––––-

DRIVETRAIN:

GEAR RATIOS:

the gear ratios is for heavily tuning your acceleration and top speed ability of your car
setting shorter gears means that your gears reach their max rpm faster (this gives you better accel)
setting taller, your gears have bigger range so they are maxed slower (less accel, more top speed)
*hint* adjust the gear ratios scaling from shorter to taller. Set the low gears (1st, 2nd 3rd) at minous (-)
and the rest at plus (+) you have better accel at low gears (which is good for drags since you
rarely use above the 4th gear) and you have better top speed ability (which is obviously good
for speed races)
and now for the scaling adjustments here is an example of setting your gears:
1st: -5
2nd: -4
3rd: -2
4th: +1
5th: +5
6th: +9
final: +10
it's a good setup for any car with some minor changes:
if you have a drag car put all adjustment one click less (aka -6 -5 -3 etc)
for a speed car adjust it plus one click (aka -4 -3 -1, leave the final at +10)
––––––––––––––––––––––

BRAKES:

BRAKE RATIO:
the percentage of pressure aplied to each set of wheels. (rear - front)
setting it to front, your car will brake faster (best for grips where you can exploit more road for accel.)
setting it to rear, the car won't brake as fast but it will be good for drifting

BRAKE/HANDBRAKE PRESSURE:
well, this is quite obvious, isn't it? just be carefull not adjusting the break pressure at the far right,
coz your car will brake by itself ;)

HOPE I HELPED YOU NEW GUYS AT TUNING

Hey there, could You give a solution to my problem? This is the problem. I adjusted the suspension to be stiffer to get better handling on the corners etc. And now my car seems to jump a lot. Could you give a fine tuning for a bmw m36? Fully tuned with works. Thanks a lot.

Well this tutorial is very informative and it contained a lot about the technical specifications. This will be very helpful if you are interested to know about the car performance, brakes and other components. It would be more helpful if you could post the images.
