the question u should be comtemplating is...wat do i plan to do with my car in the future...if ur gonna track the car or want a nice stance..then ur probably gonna wanna get coilovers down the road....then theres no need to waste $100....
if u jus want a mild drop and get some rims on there to look nice...then i dont see y u would need to get sportlines if u already have neuspeed springs....
save ur money kiddo...and decide wat u want to do with ur car in the long run...
trust me...it'll save u more money.....think it thru...dont impulse buy something jus cuz it sounds like a good deal...
^ Truth. Acorn is a style of lug nut... on the other end of the seat. So, something like using a open end, shallow lug nut with a ball seat would work too, in theory.
