as in for struts/shocks... if you don't have money... get 08-09 FE5 shocks/struts... if you DO have money then go with Koni Yellow struts and shocks... for springs if you DON'T got money, go with 2008 FE5 springs, it will lower the car a bit and improve handling by a lot vs our FE1 stock suspension.. if you got money then go with Eibach Sportline springs, it'll lower the car more than FE5 springs and will have a tad better handling
as in for tires, I wouldn't go bigger than 225 width for summer tires, no wider than 195-205s for winter, unless you're planning on doing some crazy driving.
