I have ~180k on my car. The shocks need replacing (not too bad but..) and I am going to replace them with Tokico blue shocks. I am going to Install Eibach pro springs. I ordered a rear sway bar. I put the rear sway bar on and I am happy with the noticeable improvement. There is some unwanted pitching transferred to the front of the car (very minor) but I feel new shocks would eliminate this feedback. I wish I could install all parts in independent stages and provide feedback on each change but I am not willing to install the struts with stock springs and then do it again with new springs (sorry). My car is equipped with aftermarket rims and 215/45/17 tires. The tires made a nice improvement in handling by themselves. The tires did degrade the ride of the car especially on sharp bumps (road to bridge transitions). It is obvious GM/Toyota designed the tires to be part of the suspension for NVH (Noise Vibration Harshness).
I am a mature driver that does not want a poor balanced car that is rough as a daily driver. I do like a car that handles well. I never thought I would keep this car this long but I just really like it. I will update everyone on my analysis. I will take before and after pictures so stay tuned!
