I'm going to be installing the FP lowering springs on my GT350. I previously installed the R-springs and did not replace any of the bolts. I figure since this will be the second time having everything apart, I should replace them. Does anyone know off hand which bolts are critical to replace? All of them? I noticed that FP sells a fastener kit for their handling pack but it's only listed as compatible with the GT and Ecoboost (M-FR3-FASTENA). Not sure if it would be worth using that and then adjusting for the GT350 specific bolts. (I'm not even sure which ones will be different) Any advice? Should I even worry about replacing them?
