my 240 came with the emusa coils already on it. when i got the 240 i had the guy give me the stock shocks and springs as i figured the coils were going to be crap... in reality they ride better than the eibach sport kit i had on my last car that cost 2x the price. i actually tried to break something when i first got the 240. i beat the piss out of it, hit every pothole and dip in the road. i have since stored the stock setup in the way back of my garage. im sure that a more expensive unit would perform better but so far these have held up better than i ever imagined.
