depends what power you have, i had 395rwhp and i used ACT 6 puck unsprung good for 450ft lbs, was overkill then, and now i have 280rwhp setup, and its waaay overkill. unless you have crazy power, its not really needed IMO, not sue if youve looked into unsprung or not, but for drivability, i wouldnt get one.
