ive got eibachs with pretty worn out stock shocks on and its really not that bad. i dont road race or do any autoXing or anything so perfect handling isnt the biggest priority on my list. if you have the money i would go ahead and get some aftmarket shocks at the same time, but if you dont have the money its not too big of a deal to go back in and put new shocks in, it doesnt take that long to do.
