depends what way you wanna go..
coilovers which is more of a suspension package all in 1 but will cost ya around 1k im guessing,.
also adjustable which comes in handy i guess if you wanna change ride height.
or springs, lows, super lows , ultra lows ect.. which will be around $120 a pair + labour.
also if your lowering it a resonable amount probably need a camber kit which i did, only realised after burning through 2sets on the rear in about 6months.
