 There is a way to make an Escudo and GT40 front end lift up. Use the following
 settings and race your car at the test track. At about 230 mph the front end
 should lift up.
 
 Equip the highest NA or Turbo tune-up
 
 Put spring rate to minimum for front and back
 
 Put ride height to minimum for front and back
 
 Put gear's auto setting to widest, and final to 3.000
 
 Put front down force to minimum and back to maximum
 
 Set ASM and TCS to level 0.
 
 Series awards
 
 Series awards (i.e. cars) are not purely random. Press X when a silhouetted car
 has the large black circle flashing under it to cause that car to be selected
 as the award for winning the series. Timing is crucial, since the large black
 circle only appears under a car for less than half a second. If you are too
 slow, the next car to get the large black circle will be selected.
 
 Easy horse power boost
 
 When you get a car, change the oil. It will boost the horse power by at least
 10 and only costs 250 credits.
 
 Easy money with memory card
 
 Note: Two memory cards are required for this trick. After you have earned about
 200,000 credits, purchase a car, such as the Mitsubishi 3000 GT. Upgrade it up
 to the max. This will leave you almost broke. Go home and save this car to
 memory card slot two, then return to the title screen and load your last game
 from memory card slot one. This will give you your money back, and you can now
 go home and trade from memory card slot two. The car that you just spent all
 those credits on will now only cost retail price.
 
 Easy money
 
 Go to Super Speedway in the Beginner League and keep racing the same level for
 easy money.
 
 Go to the Beginner League and race in NA to get 5,000 credits.
 
 If you have a good car, go to the Amateur League and race in NA for 10,000
 credits.
 
 If you have a very good car, go to the Amateur League and race in GT All-Stars
 in the test course to get 25,000 credits. Note: Buy the cheapest tires, as they
 last longer.
 
 Get a fast car and race the Speedway in the Final Series Race in the Beginner
 League to win 10,000 credits.

 ChickaPaulPatey@cs.com submitted the following information:
 
 Get a car with a lot of power (1,000 HP+) that 
 can go 230 MPH or more and the front and rear
 downforce can be adjusted. The Escudo Pikes Peak
 Version, R390 GT1 Race Car, or the GT-one Race 
 Car works good. 
 
 - Get the highest stage Turbo Kit or NA Tune Up. 
 
 - Put the front and rear Spring Rate as low as 
   they can go. 
 
 - Put the front and rear Ride Height as low as 
   they can go. 
 
 - Set the gear ratio's auto setting as high as it
   can go, and put the final gear fairly high 
   (at the 3/4 mark or higher). 
 
 - Put the front Downforce as low as possible, and
   the rear Downforce as high as possible. Set ASM
   and TCS to 0. 
 
 -Have fun!
 
 Go into the Grand Valley endurance race. Use a fast
 car so you can win. Once you're done the race save
 and restart the game. When you're at the main menu 
 press L2, L1, R2, R1, X. After you've done that go 
 to the Panoz dealership and press what you did at 
 the main menu. Now every time you play GT3 you'll get
 the money same amount you won in the endurance race
 
 -UFO's:
 
 Start a new Game in the FT-Mode. Finish 1 Race
 with the 1st Place, then Save the Game. Restart
 your Ps2 and set the ps2 Date to 1.1.3000. Then 
 start GT3. Load your saved Game, and you will 
 find some ufos to drive(fly) with.
 
 
 Go into options screen, and get in the controler
 options, now switch the gas pedal (X) to the 
 analog option so that the gas button is now 
 holding the right analog stick to the left, now 
 you have to have an Escudo Pikes Peak for this to
 work! Now if you have this ride and done that to 
 the controler then put a rubber band over the 
 2 analogs sticks so the are pointing towrads 
 eachother, then go to the last endurance race 
 150 mile one! If you done this right you idiot,
 you can leave for an hour then come back to find 
 out you won!!!!!
 

75% completion:
Complete 75% of the game and you will be rewarded with a Mazda 787B.
