Stock P5 >>>>> Stock Civic. Civic prolly has more readily available mods, but seeing as ur already here, you probably won't have trouble finding any parts / advice u'll need. The P5, stock, handles like it's on rails, and rides well. The only "performance" mod I've done to mine is +1 rims/tires, and it still rides really well, handles a bit better. P5 responds very well to suspension mods.
