NFS: ProStreet Tuning Guide
I know there are loads of people who either dont need this or have already seen it, but if your new to the game or a little confused then these guides will help you alot :).
Obviously to tune a car you go to Career>Continue>Cars>Garage>Pick a car>Tuning.
I didnt make these so credit to Zerotau who did, im just showing them to the people who need 'em.
Grip

Drift
Drag
