how bad an idea is that??? he says they only have 8k miles on them... they are jic, with the rear springs replaced with stiffer springs (springs that came with the kit are included), he didn't specify the model.... for 900.... i want a pretty rounded dd/autocross car, ride quality isn't too important.... the only reason i ask is because for the cheapest jic coilovers i've seen new, it's over a $500 dif, is that price dif worth it???
