The following guide will allow you to beat ToCA Race Driver 3 on PC-DVD with ease on Tier32, however
this is cheating 
but works a treat!
Download a small application called iRipper
here (748K).
Navigate to
C:\Program Files\Codemasters\Race Driver 3\gamedata\chamship
Copy a file called
champ.big to your desktop. Now rename champ.big to champ.old in the above directory, so you have a back-up copy! Much quicker than having to re-install the whole of ToCA 3!
Run iRipper and open the champ.big file you copied to your desktop. Once you've opened the champ.big file, a long list of *.ini files should be displayed. Locate a file called
forw_.ini
Right click the file and select
Edit with. On the left click
Add program. Navigate to
C:\Windows and choose Notepad.exe. Now double click on Notepad.exe.
The contents of the
forw_.ini file should now be displayed within Notepad.
Look for two entries near the top:
CareerOfferTeamID = KQMS
CareerOfferCarID = forw_03/F18
Change these so they read as follows:
CareerOfferTeamID = WMMS
CareerOfferCarID = for1_00/F27
If you scroll down further, you'll find entries relevant to each of the eight races on Tier32.
By default
CareerLapsNum = 10. You could change this to
CareerLapsNum = 2 meaning you'd only have to complete 2 laps instead of 10. To apply this setting to all tracks on Tier32, you must change the setting on each race under the headings [Race 1], [Race 2], [Race 3] etc...
Once you've made all changes you'd like, click File > Save then exit Notepad. If you now maximise iRipper you should see a message
Replace data now. Click
Yes. The
forw_.ini file will appear faded amongst the other *.ini files. Click on
Save at the top of iRipper.
You may now close iRipper and move Champ.big from your desktop back to the
C:\Program Files\Codemasters\Race Driver 3\gamedata\chamship directory.
Now run ToCA Race Driver 3 as normal and enter the World Tour. All will work as normal, apart from now you'll have the
Williams BMW FW27 car as you do in Tier31
If Gamecopyworld would like a 'pre-made' champ.big file, I can upload my copy which is only 1.99MB. Have fun!
