Thanks.
I deliberately kept the stock suspension height because the car has to clear local speed bumps, so I've only done some minor tweaks to reduce body roll so far. I plan to install urethane bushings in the Panhard bar and rear differential carrier, and refurbish the front control arms with urethane bushings and new ball joints during the summer. I already have the parts; I just need to find the time!
My existing stock shocks/struts are still good but I eventually plan to replace them with Koni STR.Ts plus new Ford Performance strut mounts and jounce stops.
