Yeah I'm not as concerned about cost as just keeping the stock ones with old fluid etc and running into issues down the road...I had the cost for coilovers in my head until I did some more looking into it anyway so it's just down to which brand...appreciate the feedback
Going with the H&R Race springs...wanted to get some feedback on shocks/struts

I thought about keeping them...everyone says keep the original battery etc etc but this car is a sentimental car for me and I don't plan to ever sell it so now I'm storing tires for the next 20+ years? I'm going to toss them and not clutter the garage space any further
