Well townie,your about to open a pandoras box.As Jmac said ask youself why you want to do anything and if your answer makes sence then ask what application you wish to use the car for.
Now head for a good book store and order a book called"how to make your car handle" by Fred Puhn,there are others around but i have found this one to be easy to read and still use it when stuck on a problem...and i'm ancient.
Lastly put your suburb details in your account as help can sometimes be closer than you think.

Cheers
Bert
