Yeah well do what we all did, Read what the threads say to do, Learn how to do it, If you still need more help just look through the threads and see what people commented and if they found an answer already, or use the search... Then after you start doing it yourself and do something wrong ask on the forums check to make sure someone didn't already answer it, Don't be another person to just come along and expect other people to do your own work, Its really not that hard... You must login or register to view this content.

and since thats probably going to be to hard for you do that, Here is a helping hand, My only one, I hope you can understand it, I'm not going to explain any further....

1) Download HXD
2) Download Bruteforce
3) Goto your PS3, start the GT5 game, Buy a new car(Keep it stock)
4) Save the game
5) Quit the game(hold the PS button)
6) Goto Save Data Utility *This next part may be hard*
7) Get a USB and plug it into the USB Port on your PS3
8 ) Scroll down to Gran Turismo Save Data, Make sure it says the Current Date and Time, and The car you just bought...
9) Hit Triangle /\, Copy, Select the USB Drive, Hit X X, Wait till it says 100% Complete
10) Remove the USB Drive
11) Plug the USB Drive into the back of your desktop or laptop
12) Open the USB Drive through Windows Explorer(My Computer)(Apple Users do wahtever you do)
13) Goto PS3 > Savedata BCU****** or Bles******* or Bce***** GT5 Save data Folder, Right Click copy Create a new folder on your desktop titled *GT5 Backup* then Paste the data into the folder
14) Open up bruteforce, Select your USB Drive, Then the GT5 Save, Then hit CTRL+D Click Yes
15) Click on GT5.0, Then go down and click Open in Explorer, Right Click on GT5.0 file Goto *Open With* Then find your HXD

17) CTRL+F search your PSN Username, it will take you to something like this > "üfrendrezz" Then go and it the [^] scroll button and click on it until you see something like this, "

Or something simmilar the code you are looking to is the one with 16 F's or 8 Y's
When you look to the left where the code actually lies you will see something like this

D2FFFF FFFFFFFF FFFF

This code is different for everyone but the FF's stay the same, You want to change the first to FF's after the body code which is the D2 (this code will vary on your car, this one I think is the one off my Nissan GT-R 02)
18 ) You are going to click the 2 Characters after that code, so the click right before the RED FF in my Text above and then change it to 74
so now it will look like this

D274FF FFFFFFFF FFFF
or if you look to the left Òtÿÿÿÿÿÿÿ.

19) Now CTR+S and Close HXD
20) Close the Windows Explorer thing with your save in it
21) Go back to bruteforce and CTRL+E click yes
22) Open it in Garage editor and start modding

*Note*
Lucas tool mods your current riding car
Slims tool can not mod your riding car

If you can not follow what I just said.... You don't need to be modding your save in the first place...
God Speed...
