Very good question, and yes it does vary
and thats a great idea.. especially for bagged cars.. when truck that are bagged have certain suspension tricks for that as car dont as much cuz its not a very common thing for bagged cars and camber prevention..
as for me... Houston roads are really nasty.. so the only time i ride low is on highway or on any area thats semi flat.. or even in parking lots of car meets or just residential areas too.. im not finished with my car.. and plan to do alot more.. im just saving lol..
