Have a 2003 Vert, 28k miles, with subframe connectors, built IRS, H&R race springs, OEM Bilsteins. It doesn't really feel sure footed under acceleration or around corners. I expect some of this due to the vert but wondering if replacing the OEM shocks and struts is a good idea, they were old now. Is this a common item to replace at this age? Or what do folks suggest?
