He needs the rear done....he has had 9 back sugerys and the thing is way to stiff in the rear...the front is pretty stock but managable so he wants to start with the back first....maybe changing the torsions or getting some different arms....i really dont know
B&R in Oceanside can help out. What does the car have now? you can just reindex the torsions out back and get rid of KYB's if that is whats on there, they will bust your kidneys all day long. Also, you can play with the tire pressures a little bit to soften it up. speed most ofetn travelled will give a better idea on what you need for suspension.
