no thanks on the GST...and yes the car can be raised, the front coils are all the way down and the rears are about an inch up on the threads so it has a long way to go, you could be able to put it up to atleast stock ride height, maybe even more if you desired...as far as getting them rebuilt you would have to get in contact with JIC, i havent had the extra cash to even see about having them rebuilt but if you wanted you could buy some megan or k sport coils and have brand new ones that will perform decent for around $800..
