I'd say stick with the b18. Although K-series are really nice engines, the one in the ep3 isn't all that great compared to the others. Just my .02. But that sucks to see how many people can't appreciate a great car like that and just don't think twice about messing it up.
Standard spring rate. Usually set the dampening somewhere in the middle a little towards the stiffer side. You have any other suspension upgrades yet? I'm really wanting to get a beefier subframe brace and sway bar.
Just sayin what's up, figured I'd post up some pics of my car to see what you guys think. Car's sittin up high for winter, but here in a few weeks it's goin back down low, just put GSR blades on it so new shots are coming.
Car looks great! Love the stance and wheels. I drove my buddy's em1 that had BC Racing coilovers and fell in love with them, he introduced me to them and I bought them the next month. Had them for a few months now and they're awesome. I love how on the softest dampened setting they feel...
