I’m new to the coil over set up and I noticed there was a price difference between this set up and 12250 and the 12350 I also noticed that there spring rates were 350lbs and 250lbs and this one is 170 lbs is this a better ride and performance application then the other 2 ? This will be going on a daily driven future weekend trackcar 1989 GTA trans am is the 12170 I better set up ? Just want to know the benefits and what is best for my car thanks !

170 lb springs are for drag racing. If you are going for a track day car you will need a higher spring rate.
