Great balence: performance oriented
Very high quality product, intensive r&d, fantastic customer service (shout out to Michelle), stiff but not cruel ride, staggering step forward in terms of cornering ability over stock set up BUT get adjustable tie rods to allow toe out after the drop, and proper alignment gear to dial in camber when you install these coils if you want to see them really shine. Also your ride will noticeably improve if you increase rear sway bar diameter and stiffness to match increases spring rates. The sway is effectively a spring itself and with a stock sway the ride will seem MUCH less civilized. This product is fantastic value at under $1k and it is designed to MOVE. If you just wanna slam your ride get something squishier. If you want to carve and actually push your DC5 or EP3, these are increadible.

All around good coilovers.
I have had these on my 2002 Civic Si for about 2 weeks now and they make a big difference over stock. Im only on a 1-1/2" drop but the ability to go lower is there. The spring and damping rates are stiff enough to cut a lot of body roll, yet still be comfortable for a daily driver imo. The only thing is that after the springs settle you have to reajust the height to make it set level. I would recomend these to anyone.
