I am trying to lower my car down about an inch to two inches I don't know how to do that without messing up the springs. Can I buy any other spring from like and honda and place them on the car ?

 

Honda! That's funny....probably not, the jag is too heavy and the strut design is totally different. Your best bet is to search...this subject has been covered here. There are quite a few very cool lowered XJ6's running around and 1 inch is easily doable in the front using some locally sourced hardware. The rears will be more difficult requiring under mounting a perch for the existing shocks to bolt to. (welding required)
