if you want a very large drop with a good ride..then you can call ground control and ask for a custom spring rate....altho it'll be kinda hard to get a low drop without a high spring rate..
hnr sport are far superior than neuspeed because over time neuspeed will sag..hnr won't..both provide a 1.75 drop too..so you'll be sitting a lil higher than your race springs gave you
