i ordered eibac sportline springs with koni yellows but ended up cancelling the order a while bac cuz i got a ticket i had to pay for. now that i almost have enough money back im reconsidering my options. whats the difference between that and like coilovers or cup suspension? i like the 2.5 inch drop with the h&r cup kit but im also concerned with performance and if it will rub on 17s. any information on what i should get is good.
