I've been looking for a speed 6 for the last year and final found the one I wanted. It's a black matic 06 with the navi and 26k miles. Some older guy had it not a young kid that fried the clutch out. I just got my Mazda speed cold air intake put on and what a difference. I'm looking for some lowering springs next. The stock ride hight leaves to much wheel wel space. I don't know if I should go with the eibach pro kit or the sport line kit. I know the sports line kit is lower but I don't want to loose my smooth ride. Any body have any input?
