Hi All I have a 2003 Spec C Ltd I am looking to upgrade the suspension. I only want to use OEM Sti parts. I am considering getting the sti 21 mm rear sway bar and 2004 rear sti pink springs. That will take me to 224lbs/inch front and 217lbs/inch rear. I was also looking at the pink sti lateral links and trailing arms with the pillowball joints. But these parts are expensive, does anyone know if it would be worth it? The car is not a daily driver. It is a weekend car, I'd also like to do the odd hillclimb event / trackdays.
