Re: Lowering a 01 gt with 18" rims???
Yah Eibach pro kit springs are probably your best bet. I'd suggest H&R's but the ride is quite noticeably stiffer than stock. The pro kit's a little more forgiving.
You may also want caster camber plates with the springs. If your shocks/struts are worn, you might as well replace them too.
