does anyone have the tanabe gf 210 springs for an ek. i was wondering about the ride quality and also how low are they. also how low can i go befor i start to hit my bump stops i plan on doing alot of auto cross and i want a low stance but i dont want it to be soo low that all it does is hit the bump stops and make the wheel skip off the ground, i already have tein s-techs but there not very stiff good stance and ride quality but i want a bit stiffer for the auto cross perpuse so thats why i was lookin at the tanabes, thanks
