well i used to have it 4inches down all the way around.. with 17s.. then the front kept bottoming out.. so i raised the front one inch.. and was fine.. but the camber on the front tires was bad.. then i traded and got the 18s which i have now. left the height the way it is.. and its fine.. the camber is fine now.. its wierd.. but my boy has 17s and its dropped 5 all the way around.. well he doesnt realy drive with it. he did when he first dropped it.. and it was bad he said.. so at shows he just drops it all the way down.. but its usually pretty low.. but the 3 4 isnt to bad.. i dont scrape much and speed bumps are no problem.
