I agree with Thai to do a search but to give you a quick reply..
You can lift your Sport with XREAS, using spacers which will give you a max of 3" of lift. There will be no problems doing this. Your XREAS will remain connected and operational. Many people use spacers for looks or practical uses (offroad clearance) with no problems. Going higher than 3" will likely cause your shock to start leaking as has happened to some people in the past.
You can search for spacers using these words SPACER LIFT, REVTECH, DAYSTAR, CORNFED.
Your alternative after that; you need to look at replacing your shocks (and coils) with something like OME (Old Man Emu), Donahoe etc, that may give you slightly more lift than spacers but much improved handling and greater capacity for offroad and weight carrying.
Search away. There's heaps on this topic.
