yeah, I'd start by getting a quality torque wrench, and a heavy duty socket that fits your wrench without adapters. Also, get a socket with the same number of sides as your bolt - don't take any chances on rounding. Be sure to make sure you're working with the right size metric/US. Then make sure you car is firmly supported and wheel chalks in use.
Next you'll have to take off enough parts so you have good access to your bolt. If it's really tight and stubborn, you're going to need a good bit of space around it. give it some WD-40 or kerosene and let that soak for a couple hours. Having your car kept warm will help both of you as well.
Now put your wrench on there, and make hard taps. Think impact wrench, bang -bang-bang. You should be able to get the bolt to move. Once it starts moving, it should be significantly easier - so make sure not to bang your fingers too hard.
