Seems that some cars drop more then others. Based on what options you have, auto or manual tranny, some cars are heaviery then others. My SE-L is a loaded Auto, with California Emissions. It's heavier then most Max's by prolly 250 lbs.
Thats why my drop with H&R is considerable.
Back to your original question..... If the installer pulls max positive camber when he installs the springs you should be OK. The only way to really find out if you need them is when you take your car in for an alignment. If camber is still out of spec, your going to need the camber bolts.
Any good alignment shop should have these in stock.
I still don't recommend Sprint springs. They are known to ride horrable and in some cases actually blow the front upper strut mounts.
