Either way, you're gonna be head over heals with your choice. I spent lots of time talking to people with full coilovers, especially he Apexi WS. I talked to a guy that road races his 5th gen, to a guy tha's had 5 different suspension setups, and both have loved their apexi's. I've found that they ride smooth as stock and really stiffen up on corners, so I don't even need to adjust them.
I don't see any group buys on the WS's right now. It's probalby just inbetween. there is almost always a 30% off all apexi buy going on.
www.rollhard.com had he cheapest web price when I checked last summer at $830
