yeah you can, just change the springs, eibach are probably the best you can get for your money, either the sprortline kit (50/30mm drop) or the pro kit (30/30mm drop all round) just because you have the sport button though dosent mean you will have the IDS+ system. the sport button improves throttle response and steering, if you have the IDS+ system it also stiffens up the shocks, very expensive system. if you have this system the dash will display an IDS symbol when you first start the ignition. the reason i say all this is do to that if you put shorter springs on, the extra load on the shocks could cause damage to them. most people replace the shocks for better ones with springs, i.e they fit VXR shocks with eibach springs as the originals arent designed to take the extra load shorter springs put on them and their lifespan becomes considerably reduced. although im not sure how true this is if you have the IDS shocks. i looked into putting ids shocks onto my H and each strut was in excess of £200+ where as all 4 vxr shocks cost this. hope this info helps
