i am anal and cheap, so i put the car on jackstands at home. take out all 4 wheels. throw the 4 in my beater. drive to a cheap place. take all the wheels out myself and hand them to the balancing dude. i dont have to worry about them raising my car and scraping it while they drive up the ramp, and wont have to worry about them taking out the lugs, scratching my rims, and over torqueing them on.
theres a place on hazard and harbor in santa ana that mounts and balance for $35, also tcmaltezza told me there is a damn ghetto ass place on la palma across from wheel warehouse that also mounts and balances for $35. they dont take care of your shiet tho. if your anal and have expensive rims do what i did.
id say go on yp.yahoo.com, search for wheel and tire stores in your area and give them all a call
