Welcome to a real simple tutorial Created for your benefit..
Most people have wished for racing wheel support in gtaiv! and now there is a chance! using asi loaders/mods and Xpadder this wish can come true!, i have figured it out for you and all is needed is a little concentration to get it working!
Bellow i have supplyed an image, dont worry, if you cannot read it use ctrl+mouse_wheel up or down for your desired resolution.
Anyways..
First make sure you have
version 1.0.4.0 of gtaiv.
You will need:
1:
an asi loader2:
filecheckfix.asi3:
firstperson.asi4:
scripthook.dll5:
A copy of Xpadder, you can purchase Xpadder at
XPadder for $9 or £5.99 if your from the UK
If you have all of these you should be ready to setup your wheel for gtaiv

Here we see Xpadder controller setup, i will guide you thru this image as best as i can if you need help just drop me a comment and ill try my best to help you.
_________________________________________________________________________________Setting up the wheel
1: first we need to create a controller setup so
press the spanner which is (1) in the image above
second we need to create a controller layout, first detect your
sticks axis movement which is (2) in the image above so click on
the [enable tick box] then click
the [Detect] button and steer your wheel all the way left then press one of your acceleration peddals, now that that is done, you need to
remove your peddle axis ..
as we will be using this later on, keep the <-> axis as it is,
bellow "<->" select it as "None" and you should be done here.
third
click ok on the controller settings layout and
click on the spanner (3) and then click the
[cursor] button which is (4) on the image above and
slide (5) all the way to the right then
press the [X] at the top right of the mouse settings box_________________________________________________________________________________Setting up the acceleration and brake is easy..
1: click the spanner again and click on:
[Image] Not this
[Sticks] Not this
[D-Pad] Not this
[Buttons]
<-------- This!!!
[Triggers] Not this
Press your brake and a new button will show up, do the same with your
accelerator and another one will show up!, now
click [OK]and
press the spanner on each one of your buttons and
select W for your accelerator button and
S for your brake button.
and you should now be done!
_________________________________________________________________________________to save the setup
press the two blue floppy disks at the top of XPadder near the spanners.
Once you have done this all you need to do is jump back into gta and you should now be able to steer the game using your wheel!
You can use your joypad/keyboard/wheel at the same time using xpadder so walking/driving/flying becomes a breeze with the right setup!
I will modifie this tutorial when i have time and make it easyer if you ask!, but first i need to have some fun! and i hope you have fun to!.
