yeah it's crazy beefy. Thanks for the info, I updated my spreadsheet. In that table there are a few rates missing though for few options namely: Whiteline sway bars and more importantly the Ford Performance Track Pack sway bars (as they are beefier than GT350R ones). Also for me based on all the spring rates it looks like Steeda minimal drop linear springs will be very close in terms of rates and drops to the new Mach 1 handling pack. Which is why I asked if they will work with OEM PP1 suspension.
